Command: ipv6 PIM exclude-genid
no ipv6 PIM exclude-genid
Function: This command configures hello messages transmitted by PIM-SM to exclude the Genid option. The no command restores the default value.
Parameters: None.
Command mode: Interface Configuration Mode
Default: Hello messages include the Genid option.
Usage guide: The command is used to interact with old Cisco IOS Versions. The command can configure on an IPv6 tunnel interface.
Example: Configure hello messages transmitted by the switch to exclude the Genid option.

active500EM(config-if-vlan1)#ipv6 PIM exclude-genid

 

10.2.2.8 ipv6 PIM hello-holdtime

Command: ipv6 PIM hello-holdtime <value>
no ipv6 PIM hello-holdtime
Function: Configure and cancel the holdtime item value in the hello message. The value describes neighbor overtime. The register of the neighbor will be deleted if the holdtime item value in the hello message is exceeded and it does not receive a neighbor hello message.
Parameters:

  • <value>: holdtime.

Command mode: Interface Configuration Mode
Default: The default value is the default hello-interval multiplied by 3.5 times the hello-interval. For example, 3.5 times the?default hello-interval of 30s, the default value of hello-holdtime is 105s.
Usage guide: If the holdtime is not set, the hello time will default to 3.5 times the hello-interval. If the hello time that is set is less than the current hello-interval, this setting will be declined. Hello-holdtime will be updated based on the following rules: if hello-holdtime is not configured, or if the configured hello-holdtime is less than the current hello-interval, the hello-holdtime will be modified to 3.5?multiplied by?the hello-interval. Otherwise, the configured value will be retained. The command can be configured on the IPv6 tunnel interface.
Example: Configure the hello holdtime setting on interface vlan1 to 10.

active500EM(config)#interface vlan1
active500EM(config-if-vlan1)#ipv6 PIM hello-holdtime 10

 

10.2.2.9 ipv6 PIM hello-interval

Command: ipv6 PIM hello-interval < interval>
no ipv6 PIM hello-interval
Function: Configure the interface PIM-DM hello message interval. The no command restores the default value.
Parameters:

  • < interval>: periodic interval for transmitting the PIM-DM hello message. The valid range is from 1s to 18724s.

Default: 30s.
Command mode: Interface Configuration Mode
Usage guide: The hello message makes the PIM-DM switch a mutual location and ensures neighborship. The PIM-DM switch announces itself by periodically transmitting hello messages to neighbors. If it doesn?t receive hello messages from neighbors within a set time, it confirms that the neighbors were lost. Configuration time is not more than neighbor overtime. The command can be configured on the IPv6 tunnel interface.
Example: Configure the PIM-DM hello interval on interface vlan1.

active500EM(config)#interface vlan1
active500EM(config-if-vlan1)#ipv6 PIM hello-interval 20

 

10.2.2.10 ipv6 PIM multicast-routing

Parameters:

  • <access-list-name>: applied access-list name

Command mode: Interface Configuration Mode
Default: No neighbor filter configuration.
Usage guide: If it is not necessary for a partner to establish neighborship, the command can filter partner PIM messages. The command can be configured on the IPv6 tunnel interface.
Example: Configure the PIM neighbor access-list on interface vlan1

active500EM(Config-if-Vlan1)#ipv6 PIM neighbor-filter myfilter
active500EM(config)#ipv6 access-list standard myfilter
active500EM(config-ipv6-std-nacl-myfilter)#deny fe80:20e:cff:fe01:facc
active500EM(config)#ipv6 access-list standard myfilter
active500EM(config-ipv6-std-nacl-myfilter)#permit any

 

10.2.2.12 ipv6 PIM scope-border

Command Mode: Interface VLAN Mode
Default: 60s.
Usage guide: The first-hop router periodically transmits stat-refresh messages to maintain PIM-DM list items of all the downstream routers. The command can modify the origination interval of state-refresh messages. The relevant timer interval is not usually modified. The command can be configured on an IPv6 tunnel interface.
Example: Configure the state-refresh message transmission interval on the interface vlan1 to 90s.

Default: Permit multicast registers from any sources to any groups.
Usage guide: This command is used to configure the access-list filtering the PIM?register packets. The addresses of the access-list respectively indicate the filtered multicast sources and multicast groups? information. For the source-group combinations that match deny, PIM sends REGISTER-STOP immediately and does not create group records when receiving?register packets. Unlike other access-lists, when the access-list is configured, the default value is permit.
Example: Configure the filtered register message?s rule to myfilter.

active500EM(config)#ipv6 PIM accept-register list myfilter

Function: Configure or disable the holdtime option in the hello packets. This value describes neighbor holdtime. If the switch hasn?t received the neighbor hello packets when the holdtime is over this neighbor is deleted.
Parameters:

  • <value>: holdtime value.

Command mode: Interface Configuration Mode
Default: The default value of holdtime is 3.5 multiplied by the Hello-interval. The hello-interval?s default value is 30s, so holdtime?s default value is 105s.
Usage guide: If this value is not configured, hellotime?s default value is 3.5 multiplied by the hello-interval. If the configured holdtime is less than the current hello-interval, the configuration will be denied. Each time hello-interval is updated, the hello-holdtime will update according to the following rules: If hello-holdtime is not configured or hello-holdtime is configured but less than the current hello-interval, hello-holdtime is modified to 3.5 multiplied by the hello-interval. Otherwise the configured value is maintained. The command can be configured on an IPv6 tunnel interface.
Example: Configure vlan1?s hello holdtime to 10s.

active500EM(config)#interface vlan1

Example: Enable ANYCAST RP debug.

active500EM#debug ipv6 PIM anycast-rp

 

10.2.4.2 ipv6 PIM anycast-rp

Command: ipv6 PIM anycast-rp
no ipv6 PIM anycast-rp
Function: Enable ANYCAST RP. The no command disables ANYCAST RP.
Parameters: None.
Command mode: Global Configuration Mode
Default: Not enabled.
Usage guide: This command will globally enable ANYCAST RP protocol. In order for ANYCAST RP to function, self-rp-address and other-rp-address set must be configured.
Example: Enable ANYCAST RP in Global Configuration Mode.

active500EM(config)#ipv6 PIM anycast-rp

 

10.2.4.3 ipv6 PIM anycast-rp

Command: ipv6 PIM anycast-rp <anycast-rp-addr> <other-rp-addr>
no ipv6 PIM anycast-rp <anycast-rp-addr> <other-rp-addr>
Function: Configure the ANYCAST RP address?ARA?and the unicast addresses of another RP communicating with this router (as a RP). The no command cancels the unicast address of another RP in accordance with the configured RP address.
Parameters:

  • <anycast-rp-addr>: RP address; the current absence of the candidate interface in accordance with the address is allowed.
  • <other-rp-addr>: unicast address of the other RP communicating with this router (as a RP).

Command mode: Global Configuration Mode
Default: Not configured.
Usage guide:
1. The anycast-rp-addr configured on this router (as a RP) is actually the RP address configured on multiple RP in the network (asscociated with the address of the RP candidate interface (or Loopback interface)). The absence of the candidate interface associated with the address is allowed when configuring.
2. Configure the other-rp-address of other RPs communicating with this router (as a RP). The unicast address identifies other RP and is used to communicate with the local router.
3. Once this router (as a RP) receives the register message from a DR unicast, it should forward it to other RP in the network to notify all the RP in the network of the source (S.G) state. While forwarding, the router will change the destination address of the register message into other-rp-address.
4. Multiple other-rp-addresses can be configured in accordance with one anycast-rp-addr. Once the register message from a DR is received, it should be forwarded to all of these other RP one by one.
Example: Configure other-rp-address in Global Configuration Mode.

active500EM(config)#ipv6 PIM anycast-rp 2000::1 2004::2

 

10.2.4.4 ipv6 PIM anycast-rp self-rp-address

Command: ipv6 PIM anycast-rp self-rp-address <self-rp-addr>
no ipv6 PIM anycast-rp self-rp-address
Function: Configure the self-rp-address of this router (as a RP). This address will be used to exclusively identify this router from other RP and to communicate with other RP. The no command cancels the configured unicast address used by this router (as a RP) to communicate with other RP.
Parameters:

  • <self-rp-addr>: unicast address used by this router (as a RP) to communicate with other RP.

Command mode: Global Configuration Mode
Default: Not configured.
Usage guide:
1. Once this router (as a RP) receives the register message from DR unicast, it needs to forward the register message to all the other RP in the network, notifying them of the source state (S.G). While forwarding the register message, this router will change the source address into self-rp-address.
2. Once this router(as a RP) receives a register message from another RP unicast, such as a register message whose destination is the self-rp-address of this router, it will create a (S,G) state and send back a register-stop message. The destination address is the source address of the register message.
3. self-rp-address has to be the address of a three-layer interface on this router but the configuration can be done in the absence of the interface.

10.2.4.5 ipv6 PIM rp-candidate

Command: ipv6 PIM rp-candidate {vlan<vlan-id> |loopback<index> |<ifname>} [<A:B::C:D>] [<priority>] no ipv6 PIM rp-candidate
Function: Add a loopback interface as a RP candidate interface based on the original PIM6-SM command. The no command cancels the oopback interface as a RP candidate interface.
Parameters:

  • <index>: loopback interface index. The valid range is 1 to 1024.
  • <vlan-id>: VLAN ID.
  • <ifname>: specified name of the interface.
  • <A:B::C:D/M>: IPv6 prefix and mask.
  • <priority>: RP election priority. The valid range is from 0 to 255. The default value is 192. The lower the value, the higher the priority.

Command mode: Global Configuration Mode
Default Setting: No RP interface is configured.
Usage guide: In order to support the ANYCAST RP function, new rules allow configuring a Loopback interface to be the RP candidate interface. The RP candidate interface should be currently unique and the address should be added into the router to ensure the PIM router can find the nearest RP. The no command can be used to cancel the RP candidate.
Example: Configure Loopback1 interface as the RP candidate interface in Global Configuration Mode.

10.2.5 Commands for PIM-SSM6

10.2.5.1 ipv6 PIM ssm

Command: ipv6 PIM ssm {default|range <access-list-name >}
no ipv6 PIM ssm
Function: Configure the PIM ssm multicast address range. The no command deletes the configured PIM ssm multicast group.
Parameters:

  • default: indicates the PIM ssm multicast group default range is ff3x::/32.
  • <access-list-number >: applying access-list name.

Command mode: Global Mode
Default: Not configured.
Usage guide:
1. Once this command is configured, PIM ssm is available.
2. Before configuring this command, ipv6 PIM multicasting must be successful.
3. Access-list can only use the lists created by the ipv6 access-list.
4. Users can execute this command first and then configure or delete the corresponding bound acl. After the binding, the no ipv6 PIM ssm command can release the bind.
5. If ssm is needed, this command should be configured at the related edge route. For example, the local switch with IGMP (required) and multicast source DR or RP (at least one of the two) configures this command. The middle switch only needs PIM-SM enabled.
Example: Configure the switch to enable PIM-SSM. The group?s range is specified by access-list 23.

active500EM(config)#ipv6 PIM ssm range 23
active500EM(config)#ipv6 access-list standard myfilter

no ipv6 access-list <8000-8099> {deny|permit} {{<source/M>}|{host-source <source-host-ip>}|any-source} {{<destination/M> }|{host-destination <destination-host-ip>}|any-destination}
Function: Configure the IPv6 source control multicast access list. The no command deletes an access list.
Parameters:

  • <8000-8099>: source control access list number.
  • {deny|permit}: deny or permit.
  • <source/M>: multicast source address and the mask length.
  • <source-host-ip>: multicast host address.
  • <destination/M>: multicast destination address and the mask length.

IPv6 multicast source control ACL only needs to configure the source and destination IPv6 address (that is the group IPv6 addresses) which are to be controlled. The configuration adopts a method similar to other ACLs, which can either be an address range configured by the mask length, a specified host address, or all addresses. For group IPv6 addresses, the ?all addresses? mentioned here is ff:/8.
Example: Configure the IPv6 source control multicast access list.

active500EM(config)#ipv6 access-list 8000 permit fe80::203:228a/64 ff1e::1/64

10.2.7.8 ipv6 mld last-member-query-interval

Command: ipv6 mld last-member-query-interval <interval>
no ipv6 mld last-member-query-interval
Function: Configure the interface?s querying specific group sending interval. The no command cancels the manually configured value and restores the default value.
Parameters:

  • <interval>: querying specific group interval. The valid range is from 1000 to 25500ms. The integer is a multiple of 1000ms. If the value entered is not a multiple of 1000ms, the system will convert it to a multiple of 1000ms.

Command mode: Interface Configuration Mode
Default: 1000ms.
Usage guide: Configure the interface?s querying specific group sending interval.
Example: Configure the interface vlan1?s MLD last-member-query-interval as 2000.

active500EM(config)#interface vlan 1
active500EM(config-if-vlan1)#ipv6 mld last-member-query-interval 2000

 

10.2.7.9 ipv6 mld limit

Command:ipv6 mld limit <state-count>
no ipv6 mld limit
Function: Configure the MLD state count limit of the interface. The no command restores the manually configured value to default value.
Parameters:

  • <state-count>: max MLD state the interface maintains. The valid range is 1-5000.

Command mode: Interface Configuration Mode
Default: 400.
Usage guide: When max state-count is configured, the number states the interface saves will not exceed the state-count limit. When the max state-count is reached, the new member qualification reports received will be ignored. If a MLD group state has been saved before this command is configured, the original states will be removed and the MLD general query will be sent to collect group member qualification reports no more than the max state-count.
Example: Set the MLD state-count limit of the interface vlan2 to 4000.

active500EM(config)#interface vlan2
active500EM(config-if-vlan2)#ipv6 mld limit 4000

 

10.2.7.10 ipv6 mld query-interval

Command: ipv6 mld query-interval <time-val>
no ipv6 mld query-interval
Function: Configure the interval of the periodically sent MLD host-query messages. The no command restores the default value.
Parameters:

  • <time-val>: interval of the periodically sent MLD host-query messages. The valid range is from 0 to 65535s.

Command mode: Interface Configuration Mode
Default: The interval of the periodically transmitted MLD query message is 125s.
Usage guide: When an interface enables a multicast protocol, it will send MLD host-query messages periodically. This command is used to configure the query period.
Example: Configure the interval of the periodically sent MLD host-query messages to 10s.

active500EM(config)#interface vlan 1
active500EM(config-if-vlan1)#ipv6 mld query-interval 10

 

10.2.7.11 ipv6 mld query-max-response-time

Command: ipv6 mld query-max-response-time <time-val>
no ipv6 mld query- max-response-time
Function: Configure the maximum MLD query response time. The no command restores the default value.
Parameters:

  • <time-val>: maximum MLD query response time. The valid range is from 1 to 25s.

Command mode: Interface Configuration Mode
Default: 10s.
Usage guide: When the switch receives a query message, the host will set a timer for each multicast group. The timer?s value is between 0 to the maximum response time. When any one of the timers decreases to 0, the host will group member announce messages. By configuring the maximum response time, the host can swiftly respond to the query messages and the router can gather the group members? existing states quickly.
Example: Configure the maximum response time of MLD queries to 20s.

active500EM(config)#interface vlan 1
active500EM(config-if-vlan1)#ipv6 mld query-max-response-time 20

 

10.2.7.12 ipv6 mld query-timeout

Command: ipv6 mld query-timeout <time-val>
no ipv6 mld query-timeout
Function: Configure the interface?s MLD query timeout value. The no command restores the default value.
Parameters:

  • <time-val>: MLD query timeout value. The valid range is from 60 to 300s.

Command mode: Interface Configuration Mode
Default: 255s.
Usage guide: In a shared network where more than one switch runs MLD, one switch will be selected as the querying host and others will set a timer to inspect the querying host?s state. If no querying packet is received when the timeout is over, a switch will be reselected as the querying host.
Example: Configure the interface?s MLD query timeout value to 100s.

active500EM(config)#interface vlan 1
active500EM(config-if-vlan1)#ipv6 mld query-timeout 100

 

10.2.7.13 ipv6 mld static-group

Command: ipv6 mld static-group <group-address> [source <source-address>] no ipv6 mld static-group <group-address> [source <source-address>]
Function: Configure certain static groups or static sources on the interface. The no command cancels certain previously configured static groups or static sources.
Parameters:

  • <group-address>: valid IPv6 multicast address.
  • <source-address>: valid IPv6 unicast address.

Command mode: Interface Configuration Mode
Default: No static groups or static sources are configured on the interface.
Usage guide: The valid range of the static group multicast address configured by the interface is the dynamic multicast address specified by the IPv6 protocol. Once the interface configures the static group or static source for the multicast address (even if there is no membership qualification report of this group or source in the subnet), MLD protocol will consider that the group or source exists. The configured static source is the source to be forwarded.
Example: Configure a MLD static-group ff1e::1:3 on interface vlan2.

active500EM(config)#interface vlan 2
active500EM(config-if-vlan2)#ipv6 mld static-group ff1e::1:3

Configure a static source 2001::1 of the group ff1e::1:3 on interface vlan2

active500EM(config)#interface vlan 2
active500EM(config-if-vlan2)#ipv6 mld static-group ff1e::1:3 source 2001::1

 

10.2.7.14 ipv6 mld version

Command: ipv6 mld version <version-no>
no ipv6 mld version

Parameters:

  • <version-no>: MLD protocol version number. The valid range is from 1 to 2.

Command mode: Interface Configuration Mode
Default: 2.
Usage guide: The interface should be configured to the corresponding version if there are routers on the connected subnet that are not upgraded to MLD protocol version 2. The interface should be configured to corresponding version.
Example: Configure the MLD version to 2.

active500EM(config)#interface vlan 1
