The peer sa-request-policy command configures the filtering policy to respond to the Source Active (SA) Request messages sent by a specified MSDP peer. After the SA Request message passes the filtering, the FW responds to the SA message immediately.
The undo peer sa-request-policy command restores the default configuration.
peer peer-address sa-request-policy [ acl basic-acl-number ]
undo peer peer-address sa-request-policy
| Parameter | Description | Value |
|---|---|---|
| peer-address | Specifies the address of MSDP peer that sends the SA Request message. | The value is in dotted decimal notation. |
| acl basic-acl-number | Indicates the number of a basic ACL. | The value is an integer ranging from 2000 to 2999. |
By default, the FW responds to all SA request messages sent by all MSDP peers.
If the ACL is not specified, all SA Requests of the MSDP peer are ignored. If the ACL is specified, only the SA Request message of a group that meets the requirements of the ACL is processed.
The peer sa-request-policy command and the acl command are used together. In the ACL view, you can set the multicast group address range of SA messages that are forwarded by the MSDP peer by specifying the source parameter in the rule command.
This command is cyclical. The latest command overwrites the previous one, and takes effect.
# Configure the ACL to filter SA request messages sent by the MSDP peer 10.58.6.5: only SA request messages bound for the group with the address of 225.1.1.0/24 are received.
