anycast
Syntax [no] anycast rp-ip-address
Context config>service>vprn>pim>rp
Description This command configures a PIM anycast protocol instance for the RP being configured. Anycast
enables fast convergence when a PIM RP router fails by allowing receivers and sources to rendezvous
at the closest RP.
The no form of the command removes the anycast instance from the configuration.
Default none
Parameters rp-ip-address — Configure the loopback IP address shared by all routes that form the RP set for this
anycast instance. Only a single address can be configured. If another anycast command is entered
with an address then the old address will be replaced with the new address. If no ip-address is
entered then the command is simply used to enter the anycast CLI level.
Values Any valid loopback address configured on the node.
rp-set-peer
Syntax [no] rp-set-peer ip-address
Context config>service>vprn>pim>rp>anycast
Description This command configures a peer in the anycast rp-set. The address identifies the address used by the
other node as the RP candidacy address for the same multicast group address range as configured on
this node.
This is a manual procedure. Caution should be taken to produce a consistent configuration of an RP-
set for a given multicast group address range. The priority should be identical on each node and be a
higher value than any other configured RP candidate that is not a member of this rp-set.
Although there is no set maximum of addresses that can be configured in an rp-set, up to 15 multicast
addresses is recommended.
The no form of the command removes an entry from the list.
Default None
Parameters ip-address — Specifies the address used by the other node as the RP candidacy address for the same
multicast group address range as configured on this node.
