2. Configure ANYCAST RP v4
1. Enable ANYCAST RP v4 function
Command Explanation
Global Configuration Mode
ip pim anycast-rp
no ip pim anycast-rp
Enable ANYCAST RP function. (necessary)
No operation will globally disable ANYCAST
RP function.
2. Configure ANYCAST RP v4
(1) Configure the RP candidate
Command Explanation
Global Configuration Mode
ip pim rp-candidate {vlan<vlan-id>
|loopback<index> |<ifname>} [<A.B.C.D>]
[>]
no ip pim rp-candidate
Now, the PIM-SM has allowed the Loopback
interface to be a RP candidate.(necessary)
Please pay attention to that, ANYCAST RP
protocol can configure the Loopback interface
or a regular three-layer VLAN interface to be
the RP candidate. In make sure that PIM
routers in the network can find where the RP
locates, the RP candidate interface should be
added into the router.
No operation will cancel the RP candidate
configuration on this router.
(2) Configure self-rp-address (the RP address of this router)
Command Explanation
Global Configuration Mode
ip pim anycast-rp self-rp-address A.B.C.D
no ip pim anycast-rp self-rp-address
Configure the self-rp-address of this router
(as a RP). This address can be used to
exclusively identify this router when
communicating with other RP.
the effect of self-rp-address refers to two
respects:
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.
