Updating IPv6 PIM Sparse forwarding entries with a new RP configuration
If you explicitly specify the RP, the device uses the specified RP for all
NOTE
Specify the same IP address as the RP on all IPv6 PIM Sparse routers within the IPv6 PIM Sparse domain. Make sure the device is on the backbone or is otherwise
To specify the IPv6 address of the RP, enter commands such as the following.
device(config)# ipv6 router pim
The command in the previous example identifies the router interface at IPv6 address 31:207 as the RP for the IPv6 PIM Sparse domain. The device will use the specified RP and ignore
To specify the IPv6 address of the RP for a specified VRF, enter commands such as the following.
device(config)# ipv6 router pim vrf blue
Syntax: [no] rp-address ipv6-addr
The ipv6-addr parameter specifies the IPv6 address of the RP.
Updating IPv6 PIM Sparse forwarding entries with a new RP configuration
If you make changes to your static RP configuration, the entries in the IPv6 PIM Sparse multicast forwarding table continue to use the old RP configuration until they are aged out.
The clear IPv6 pim
To update the entries in an IPv6 PIM Sparse static multicast forwarding table with a new RP configuration, enter the following command at the privileged EXEC level of the CLI.
device(config)# clear ipv6 pim
Syntax: clear ipv6 pim [ vrf vrf_name ] rp-map
Embedded Rendezvous Point
Global deployment of IPv4 multicast relies on Multicast Source Discovery Protocol (MSDP) to convey information about the active sources. Because IPv6 provides more address space, the RP address can be included in the multicast group address.
NOTE
The IPv6 group address must be part of the FF70:/12 prefix.
Embedded RP support is enabled by default. You can disable it using the following commands.
device(config)# ipv6 router pim
