44.5.3 ip pim anycast-rp
Command:
ip pim anycast-rp <anycast-rp-addr> <other-rp-addr>
no ip pim anycast-rp <anycast-rp-addr> <other-rp-addr>
Function:
Configure ANYCAST RP address (ARA) and the unicast addresses of other RP communicating with
this router (as a RP). The no operation of this command will cancel the unicast address of another
RP in accordance with the configured RP address.
Parameters:
anycast-rp-addr: RP address, the absence of the candidate interface in accordance with the
address is allowed.
other-rp-addr: The unicast address of other RP communicating with this router (as a RP).
Command Mode:
Global Configuration Mode.
Default:
There is no configuration by default.
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, in accordance with the address of RP candidate interface (or Loopback
interface). The current absence of the candidate interface in accordance with the address is allowed
when configuring.
2. Configure the other-rp-address of other RP 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.
