Explanation
Now, the P IM-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 candidat e. In make sure that P IM
routers in the network can find where the RP
locates, the RP candidat e interface should be
added into the router.
No operation will cancel the RP candidate
configuration on this rout er.
Explanation
Configure the self-rp-address of this router
(as a RP). This address can be used to
exclusively identify
communicating with other RP.
the effect of self-rp-addre ss refers to two
respects:
1 Once this router (as a RP) receives the
register message from DR unicast, it needs to
forward t he 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 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 t o communicate with other RPs
