39.4.3 ipv6 pim anycast-rp
Command: ipv6 pim anycast-rp <anycast-rp-addr>
no ipv6 pim anycast-rp <anycast-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 current 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 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.
Switch(config)#ipv6 pim anycast-rp 2000::1 2004::2
39.4.4 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 operation of this command
will cancel the configured unicast address used by this router (as a RP) to communicate with other RP.
Parameters: self-rp-addr: The unicast address used by this router (as a RP) to communicate with other
RP.
Command Mode: Global Configuration Mode.
Default: No self-rp-address is configured by default.
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 state of source (S.G). While
forwarding the register message, this router will change the source address of it into self-rp-address.
2. Once this router(as a RP) receives a register message from other RP unicast, such as a register
message whose destination is the self-rp-address of this router, it will create (S,G) state and send back a
