Multicast Configuration Guide
OL-
Step 4
exit
Example:
RP/0/0/CPU0:router(config-if)# end
Exits interface configuration mode, and returns the router to
global configuration mode.
Step 5
router msdp
Example:
RP/0/0/CPU0:router(config)# router msdp
Enters MSDP protocol configuration mode.
Step 6
default-peer ip-address [prefix-list list]
Example:
RP/0/0/CPU0:router(config-msdp)# default-peer
172.23.16.0
(Optional) Defines a default peer from which to accept all
MSDP SA messages.
Step 7
originator-id type interface-path-id
Example:
RP/0/0/CPU0:router(config-msdp)# originator-id
pos 0/1/1/0
(Optional) Allows an MSDP speaker that originates a
(Source-Active) SA message to use the IP address of the
interface as the RP address in the SA message.
Step 8
peer peer-address
Example:
RP/0/0/CPU0:router(config-msdp)# peer
172.31.1.2
Enters MSDP peer configuration mode and configures an
MSDP peer.
• Configure the router as a BGP neighbor.
• If you are also BGP peering with this MSDP peer, use
the same IP address for MSDP and BGP. You are not
required to run BGP or multiprotocol BGP with the
MSDP peer, as long as there is a BGP or multiprotocol
BGP path between the MSDP peers.
Step 9
connect-source type interface-path-id
Example:
RP/0/0/CPU0:router(config-msdp-peer)#
connect-source loopback 0
(Optional) Configures a source address used for an MSDP
connection.
Step 10
mesh-group name
Example:
RP/0/0/CPU0:router(config-msdp-peer)#
mesh-group internal
(Optional) Configures an MSDP peer to be a member of a
mesh group.
Step 11
remote-as as-number
Example:
RP/0/0/CPU0:router(config-msdp-peer)# remote-as
250
(Optional) Configures the remote autonomous system
number of this peer.
