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 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.
