Hey Folks,
I'm looking for information on various core network architectures that
could harden a control plane or prevent/isolate the propagation of say a
malformed packet/control plane issue. I know that a part of the problem
can be solved with edge filtering, ebgp, defense in depth and MD5 auth,
but I am looking for a solution that might involve multi-level IS-IS.
Any pointers would be a help.
Thanks
Frank
