By configuring the same mesh group name for multiple MSDP peers, you can create a mesh group
that contains these MSDP peers.
Before grouping multiple routers into an MSDP mesh group, make sure that these routers are
interconnected with one another.
To create an MSDP mesh group:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter public network MSDP
view or VPN instance MSDP
view.
msdp
[
vpn-instance
vpn-instance-name
]
N/A
3.
Create an MSDP mesh
group and assign an MSDP
peer to that mesh group.
peer
peer-address
mesh-group
name
An MSDP peer does not belong to
any mesh group by default.
If you assign an MSDP peer to
multiple mesh groups, only the
last configuration is effective.
Configuring MSDP peer connection control
IMPORTANT:
The MSDP peers involved in MD5 authentication must be configured with the same authentication
method and password. Otherwise, the authentication fails and the TCP connection cannot be
established.
MSDP peers are interconnected over TCP (port number 639). You can flexibly control sessions
between MSDP peers by manually deactivating and reactivating the MSDP peering connections.
When the connection between two MSDP peers is deactivated, SA messages will no longer be
delivered between them, and the TCP connection is closed without any connection setup retry. The
configuration information, however, remains unchanged.
A TCP connection is required in the following situations:
•
When a new MSDP peer is created
•
When a previously deactivated MSDP peer connection is reactivated
•
When a previously failed MSDP peer attempts to resume operation
You can adjust the interval between MSDP peering connection retries.
To enhance MSDP security, configure a password for MD5 authentication used by both MSDP peers
to establish a TCP connection. If the MD5 authentication fails, the TCP connection cannot be
established.
