Figure 94. MSDP Default Peer, Scenario 4
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.
Example of the ip msdp default-peer Command and Viewing Denied Sources
DellEMC(conf)#ip msdp peer 10.0.50.2 connect-source Vlan 50
DellEMC(conf)#ip msdp default-peer 10.0.50.2 list fifty
DellEMC(conf)#ip access-list standard fifty
DellEMC(conf)#seq 5 permit host 200.0.0.50
DellEMC#ip msdp sa-cache
