Chapter 45 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.
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 gigabitethernet1/0/1
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.
Beginning in privileged EXEC mode, follow these steps to create a mesh group. This procedure is
optional.
To remove an MSDP peer from a mesh group, use the
no
ip msdp mesh-group
name
{
ip-address
|
name
} global configuration command.
Shutting Down an MSDP Peer
If you want to configure many MSDP commands for the same peer and you do not want the peer to
become active, you can shut down the peer, configure it, and later bring it up. When a peer is shut down,
the TCP connection is terminated and is not restarted. You can also shut down an MSDP session without
losing configuration information for the peer.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 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.
Step 3
end
Return to privileged EXEC mode.
Step 4
show running-config
Verify your entries.
Step 5
copy running-config startup-config
(Optional) Save your entries in the configuration file.
Step 6
Repeat this procedure on each MSDP peer in the group.
