I think I can also see a way to reduce the number of seesion by making a
hub-and-spoke topology.
Then I can reduce MP-ibgp session to 3 ( from one HUB PE to three spoke PE),
correct?
Of course, in this case, RIP or OSPF needs in VRFA in order to achieve a
full reachability between spoke?
Someone correct me if I am wrong.
Thanks
