rp-address: IP address of RP.

max-hops: The maximum number of hops that are traced, ranging from 1 to 255. 
By default, the value is 16.

next-hop-info: Specifies flag bit for collecting the next hop information.

Use the msdp-tracert command to trace the transmission path of SA messages in 
the network, which helps to locate the faults such as information loss and 
configuration error. After the transmission path of SA messages is determined, 
correct configuration can avoid the overflow of SA messages.
