# Configure the same Loopback10 interface address on SwitchC and SwitchD and
configure the locations of C-BSR and C-RP. The configuration procedure on SwitchD is
similar to that on SwitchC. The details are omitted here.
[SwitchC] interface loopback 10
[SwitchC-LoopBack10] ip address 10.1.1.1 255.255.255.255
[SwitchC-LoopBack10] pim sm

3) Configure an MSDP peer
# Configure an MSDP peer on Loopback0 on SwitchC.
[SwitchC] msdp
[SwitchC-msdp] originating-rp loopback0
[SwitchC-msdp] peer 2.2.2.2 connect-interface loopback0
[SwitchC-msdp] quit
# Configure an MSDP peer on Loopback0 on SwitchD.
[SwitchD] msdp
[SwitchD-msdp] originating-rp loopback0
[SwitchD-msdp] peer 1.1.1.1 connect-interface loopback0
[SwitchD-msdp] quit

8.7 Troubleshooting MSDP Configuration

8.7.1 MSDP Peer Always in the Down State

I. Symptom
An MSDP peer is configured, but it is always in the down state.
II. Analysis
An MSDP peer relationship between the locally configured connect-interface
interface address and the configured peer address is based on a TCP connection. If the
address of local connect-interface interface is inconsistent with the peer address
configured on the peer router, no TCP connection can be established. If there is no
route between the two peers, no TCP connection can be established.
III. Solution
1) Check the connectivity of the route between the routers. Use the display ip
routing-table command to check that the unicast route between the routers are
correct.
