Chapter 44 IPv6 Multicast Protocol

2. Configure ANYCAST RP v6

(1) Configure RP candidate

Command

Explanation

Global Configuration Mode

ipv6 pim rp-candidate {vlan<vlan-id>

|loopback<index> |<ifname>}

[<A:B::C:D>][<priority>]

no ipv6 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

configured on this router.

(2) Configure self-rp-address (the RP communication address of this router)

Command

Explanation

Global Configuration Mode

ipv6 pim anycast-rp self-rp-address

A:B::C:D

no ipv6 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.(necessary)

the effect of self-rp-address refers to two

respects:

1 Once this router (as a RP) receives the register

message from a 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

self-rp-address of this router, it will create (S,G)

state and send back a register-terminating

message, whose destination address is the

source address of the register message.

Pay attention: self-rp-address has to be the

address of a three-layer interface on this router,

but the configuration is allowed to be done with
