[c-nsp] IGP advertisment

[Arie Vayner (avayner)]

Chintan,

Traceroute will keep working (as long as the destination is a loopback).
You can still telnet/ping physical interfaces from directly attached
routers, so if you troubleshoot a L2 issue - you do not lose much
capabilities.

Subject: [c-nsp] IGP advertisment

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?

Thanks,
Chintan
