Switch(router-msdp-peer)# sa-filter in list 120

38.4.27 sa-request

Command: sa-request

no sa-request

Function: To configure the route sending SA request message to specified MSDP Peer when received

the joined message from a new group.

Parameter: None.

Command Mode: MSDP Peer Configuration Mode.

Default: Not sending SA Request message by default.

Usage Guide: This command makes the switch (RP) send SA request messages to the specified MSDP.

When there is a new group or member, the switch (RP) will send SA request messages to the specified

MSDP and wait for the latter’s response of its cached local SA messages. After sending a SA message to

the specified MSDP, RP will receive a SA_response message from the peer, and know all active sources

of the peer (not including the source information learnt via MSDP SA). If RP is configured with SA cache

state, this configuration won’t take effect. This command is mutually exclusive to sa-cache-sate. If the

MSDP is configured with SA cache state, it won’t be able to configure sa-request. The switch will show a

prompt to notice the users. Please notice this command only applies to RP.

Example:

Switch(config)#router msdp

Switch(router-msdp)#peer 20.1.1.1

Switch(router-msdp-peer)# sa-request

Parameter: access-list-number: ACL number, only supported standard ACL from 1 to 99.

Default: The route receives all the SA request messages from MSDP Peer.

Usage Guide: If no list parameter is specified, all the SA request messages from MSDP Peers will be

filtered. If specified, SA request messages will be filtered with the specified ACL list.
