Specifying Source-Active Messages
To specify messages, use the following command.
Specify the forwarding-peer and originating-RP from which all active sources are accepted without regard for the RPF
check.
CONFIGURATION mode
ip msdp default-peer ip-address list
If you do not specify an access list, the peer accepts all sources that peer advertises. All sources from RPs that the ACL
denies are subject to the normal RPF check.
