Specifying an MSDP peer
An MSDP peering relationship is identified by an address pair (the addresses of the local MSDP peer
and the remote MSDP peer). To create an MSDP peering connection, you must perform the following
operation on both devices that are a pair of MSDP peers.
If an MSDP peer and a BGP or MBGP peer share the same interface, specify the MSDP peer and the
BGP or MBGP peer by using the same IP address.
To specify an MSDP peer:
Step
1.
Enter system view.
2.
Enter MSDP view.
3.
Specify an MSDP
peer.
Configuring a static RPF peer
This feature prevents SA messages forwarded by the static RPF peer from undertaking the RPF
check. This simplifies the RPF check mechanism for SA messages.
You can configure an RP policy for the static RPF peer to filter SA messages based on the used IPv4
prefix list that specifies the RP addresses.
If only one MSDP peer is configured on a router, this MSDP peer is considered to be a static RPF
peer.
To configure a static RPF peer:
Step
1.
Enter system view.
2.
Enter MSDP view.
3.
Configure a static RPF
peer.
Configuring an MSDP peering connection
This section describes how to configure an MSDP peering connection.
Configuration prerequisites
Before you configure an MSDP peering connection, complete the following tasks:
•
Configure a unicast routing protocol so that all devices in the domain can interoperate at the
network layer.
•
Configure basic MSDP features.
Configuring a description for an MSDP peer
This feature helps administrators easily distinguish an MSDP peer from other MSDP peers.
