Parameter
peer-address: Address from which the local router receives SA request messages sent
by the specified MSDP peer.
acl acl-number: Number of basic IP ACL, describing multicast group address, ranging
from 2000 to 2999. If no ACL is specified, all SA request messages will be ignored.
Description
Use the peer sa-request-policy command to limit SA request messages that the
router receives from MSDP peers.
Use the undo peer sa-request-policy command to remove the limitation.
By default, the router receives all SA request messages from the MSDP peer.
If no ACL is specified, all SA requests will be ignored. If ACL is specified, only those SA
request messages from the groups permitted by the ACL will be processed and all the
others will be ignored.
Related command: peer.
Example
# Configure the ACL for filtering SA request messages from the MSDP peer 175.58.6.5.
The SA request messages from group address range 225.1.1.0/8 will be received and
all the others will be ignored.
