220Step Command Remarks3. Configure a static RPF peer. static-rpf-peer peer-address[ rp-policy ip-prefix-name ]No static RPF peer is configured bydefault.NOTE:If only one MSDP peer is configured on a router, this MSDP will be registered as a static RPF peer.Configuring an MSDP peer connectionBefore you configure an MSDP peer connection, complete the following tasks:• Configure any unicast routing protocol so that all devices in the domain are interoperable at thenetwork layer.• Configure basic MSDP functions.• Determine the description of MSDP peers.• Determine the name of an MSDP mesh group.• Determine the MSDP peer connection retry interval.• Determine the MD5 authentication password for the TCP connection to be established with anMSDP peer.Configuring MSDP peer descriptionWith the MSDP peer description information, the administrator can easily distinguish different MSDPpeers to better manage MSDP peers.To configure description for an MSDP peer:Step Command Remarks1. Enter system view. system-view N/A2. Enter public network MSDPview or VPN instance MSDPview.msdp [ vpn-instancevpn-instance-name ] N/A3. Configure description for anMSDP peer. peer peer-address description text No description is configured for anMSDP peer by default.Configuring an MSDP mesh groupAn AS can contain multiple MSDP peers. You can use the MSDP mesh group mechanism to avoid SAmessage flooding among these MSDP peers and optimize the multicast traffic.An MSDP peer in an MSDP mesh group forwards SA messages (that have passed the RPF check) fromoutside the mesh group to the other members in the mesh group. A mesh group member accepts SAmessages from inside the group without performing an RPF check, and does not forward the message
