Configuring an MSDP Peer
MSDP peer relationships need be set up between RPs. If there are more than three devices, MSDP peer relationships should be set up between any two devices and all MSDP peers should be added to one mesh group.
Context
Perform the following steps on multiple FWs on which an anycast RP is to be created:
If the number of FWs configured with the RPs that have the same IP address exceeds two, ensure the interconnection between the FWs that set up MSDP peer relationship.
Procedure
- Access the system view.
- Enable MSDP in the public network instance or the VPN instance
and access the MSDP view.
msdp [ vpn-instance vpn-instance-name ]
- Create an MSDP peer connection.
peer peer-address connect-interface interface-type interface-number
The parameters of the command are explained as follows:
peer-address: specifies the address of a remote MSDP peer.
interface-type interface-number: specifies the local interface.
- (Optional) Add description of the MSDP peer.
peer peer-address description text
This configuration helps to differentiate remote MSDP peers and manage the connection with the remote MSDP peers.
The parameters of the command are explained as follows:
peer-address: specifies the address of a remote MSDP peer.
text: specifies the description text. The text is a string of 80 characters.
- (Optional) Configure a remote MSDP peer to join a mesh
group.
peer peer-address mesh-group name
That is, the remote MSDP peer is acknowledged as a member of the mesh group.
If only two FWs are configured with the anycast-RP, this configuration is not necessary.
The parameters of the command are explained as follows:
peer-address: specifies the address of a remote MSDP peer.
name: specifies the name of a mesh group. The members of the same mesh group use the same mesh group name.
Note the following:
MSDP peer connections must be set up between all members of the mesh group.
All members of the mesh group must acknowledge each other as the member of the mesh group.
An MSDP peer belongs to only one mesh group. If an MSDP peer is configured to join different mesh groups for many times, only the last configuration is valid.
