43.4.8 MSDP Troubleshooting
When MSDP is being configured, it may not function because of the physical link not working or configuration
mistakes. Attention should be paid to the following items in order to make MS DP work:
Make sure the physical link works well
Make sure inner-domain and inter-domain routing works
Make sure PIM-SM is applied in every domain as the inner-domain routing protocol, and configuration
for PIM-SM works well
Make sure MS DP is enabled, and the link status of the MSDP enabled Peer is UP
Use the command show msdp global to check whether the MSDP configuration is correct
