Chapter 43 Ipv4 Multicast Protocol

43-27

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 register-stop

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 the absence of the interface. The

self-rp-address should be unique.

No operation will cancel the self-rp-address

which is used to communicate with other RPs

by this router (as a RP).

(3) Configure other-rp-address (other RP communication addresses)

Command

Explanation

Global Configuration Mode

ip pim anycast-rp <anycast-rp-addr>

<other-rp-addr>

no ip pim anycast-rp <anycast-rp-addr>

<other-rp-addr>

Configure anycast-rp-addr on this router (as a

RP). This unicast address 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 effect of anycast-rp-addr includes:

1 Although more than one anycast-rp-addr

addresses are allowed to be configured, only

the one having the same address with the

currently configured RP candidate address

will take effect. Only after that, can the

other-rp-address in accordance with this

anycast-rp-addr take effect.

2 The configuration is allowed to be done with

the absence of the interface in accordance

with the anycast-rp-addr.

Configure on this router (as a RP) the

other-rp-addresses of other RP

communicating with it. This unicast address

identifies other RP and is used in the

communication with local routers.

The effect of other-rp-address refers to two

respects:
