MSDP peers communicate through TCP connections. You can flexibly control the sessions set up between MSDP peers by ending or reestablishing TCP connections. In addition, you can also adjust the interval for retrying to set up MSDP peer connections and configure MSDP peer authentication to improve the security of TCP connections.
A router can work normally with default control parameters. You are allowed to adjust the interval for retrying to set up MSDP peer connections if the default interval does not fit your network requirements.
If there is no special requirement, default parameter values are recommended.
Before configuring MSDP peer connection control, complete the following tasks:
Configure a unicast routing protocol to ensure that unicast routes are reachable.
Configure PIM-SM inter-domain multicast or configure Anycast-RP.
