www.dell.com | support.dell.com Task Command Syntax Specify the forwarding-peer and originating-RP from which all active sources are accepted without regard for the RPF check. If you do not specify an access list, the peer accepts all sources advertised by that peer. All sources from RPs denied by the ACL are subjected to the normal RPF check. ip msdp default-peer ip-address list Command Mode CONFIGURATION Figure 30-11.

Set the upper limit for the number of sources allowed from an MSDP peer. The default limit is 100K. Command Syntax ip msdp cache-rejected-sa ip msdp peer peer-address sa-limit Command Mode CONFIGURATION CONFIGURATION If the total number of sources received from the peer is already larger than the limit when this configuration is applied, those sources are not discarded. To enforce the limit in such a situation, first clear the SA cache. 642 | Multicast Source Discovery Protocol (MSDP)
