Hi All, I know this may sound like a CCIE Lab question, but its not.
The info I find on interweb is confusing and it seems not to be working. Maybe someone is willing to spend 10mins to setup quick lab and help me. So the issue: I have 3 routers connected in triangle. A connected to B and C, and B connected to C. Running ISIS level2 on all three and advertising loopbacks. A needs to change the AD to 15 for loopback IP advertisements (loopback IPs for B & C) from router B. A needs to change the AD to 15 for ONLY loopback C from advertisements from router C. Does this make sense I have tried multiple different configs and I do not get the required result. The real life problem is A and B are PE routers and C is the RR. So I do not have MPLS on the interfaces towards C from A & B. So when the A-B link fails, it will break the label switched path between them. A and B have CsC links which should then be preferred.. Please advise. Thinking if maybe changing IGP to OSPF.
