7.7.3 (Optional) Configuring the Filtering Rules for Receiving SA
Request Messages
You can configure rules for filter the SA Request messages received from the local device on a
specified remote MSDP peer. If the SA Request message passes the filtering, the peer
immediately responds.
Context
Do as follows on the remote MSDP peer specified by using the peer peer-address request-sa-
enable command. If the configuration is not done, once an SA message reaches, the switch
immediately responds to it with an SA message containing the required (S, G) information.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
msdp [ vpn-instance vpn-instance-name ]
The MSDP view is displayed.
Step 3 Run:
peer peer-address sa-request-policy [ acl { basic-acl-number | acl-name } ]
The filtering rules for receiving SA Request messages are set.
l peer-address: specifies the address of an MSDP peer that sends the SA Request message.
l acl: specifies the filtering policy. If the ACL is not specified, all SA messages sent by a peer
are ignored. If the ACL is specified, only the SA messages that match the ACL are received
and other SA messages are discarded.
----End
