Hi ,

As of now we have all /30 and /32 network being advertised in our IP/MPLS
network running IS-IS in L1 and L2. so all PE have total number of IGP
routes in network in their routing table.
We plan to implement to advertise only loopback of P and PE in IGP to reduce
memory and also for better convergance.

I think i can do that without any issue but i worry that our operation team
may not be agree since they may loose troubleshooting flexibity like
traceroute , telnet to interface etc ...

Can some on share some light on this with some advantage /disadvantage in
real enviroment?
