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>
no ip pim anycast-rp <anycast-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:
