Hi Sheikh,
ip msdp mesh-group is for optimizing the SA messages when more
than 2 peers are fully meshed. To answer your question - Its not neccessary
for basic msdp without bgp.. ip msdp default-peer command is enough for basic
msdp without bgp.
The mesh-group command is used for reducing the amount of
SA traffic in the network. SAs are not flooded to other mesh-group peers.
No
RPF checks are performed on arriving SA messages. When received from a
mesh-group peer SAs always accepted from mesh-group peers.
HTH..
Thanks,
Vidhya

this topic. Do you think "ip msdp mesh-group" command is required while
configuring basic MSDP with out bgp. In my lab it works with or without it,
therefore not sure whether to keep this in the config or not.
