Configuring MSDP
Configuring MSDP
To remove the filter, use the no ip msdp sa-filter in {ip-address | name} [list access-list-number] [route-map map-tag]
global configuration command.
EXAMPLE
This example shows how to filter all SA messages from the peer named switch.cisco.com:
Switch(config)# ip msdp peer switch.cisco.com connect-source gigabitethernet0/1
Switch(config)# ip msdp sa-filter in switch.cisco.com
Configuring an MSDP Mesh Group
An MSDP mesh group is a group of MSDP speakers that have fully meshed MSDP connectivity among one another. Any
SA messages received from a peer in a mesh group are not forwarded to other peers in the same mesh group. Thus, you
reduce SA message flooding and simplify peer-RPF flooding. Use the ip msdp mesh-group global configuration
command when there are multiple RPs within a domain. It is especially used to send SA messages across a domain. You
can configure multiple mesh groups (with different names) in a single switch. This procedure is optional.
DETAILED STEPS
To remove an MSDP peer from a mesh group, use the no ip msdp mesh-group name {ip-address | name} global
configuration command.
EXAMPLE
The following example shows how to configure the MSDP peer at address 192.168.1.3 to be a member of the mesh
group named internal:
Switch(config)# ip msdp mesh-group internal 192.168.1.3
Table 0-8
Command Purpose
1. configure terminal Enter global configuration mode.
2. ip msdp mesh-group name
{ip-address | name}
Configure an MSDP mesh group, and specify the MSDP peer
belonging to that mesh group.
By default, the MSDP peers do not belong to a mesh group.
For name, enter the name of the mesh group.
For ip-address | name, enter the IP address or name of the
MSDP peer to be a member of the mesh group.
3. end Return to privileged EXEC mode.
4. show running-config Verify your entries.
5. copy running-config
startup-config
(Optional) Save your entries in the configuration file.
6. Repeat this procedure on each MSDP peer in the group.
