10.x.47.25 is the loopback 0 of connected router with dark fiber. How should I do?
Thank you very much.
Solved! Go to Solution.
Are you aware of any physical issue, unstable links ?
Show cpu process sorted - Do you have high cpu utilization? -
Sh clns neighbors - no both peering rtrs
hard to determine what causes the flapping without seeing the configurations, can you post those ? I have a feeling that it has to do with IS-IS running over an EtherChannel (which uses a lload balancing scheme that might disrupt IS-IS).
Can you post the output of 'show interfaces x' where 'x' are the interfaces on both sides (this is to check if there are errors or dropped packets on these interfaces) ?
I am doing re-design my customer network, can someone tell me how many routers we can have per IS-IS process.
How many processes, instances, routes supported by routers (ASR9K, ASR 903, ASR902, ASR901, ASR 920).
RSPs (RSP3, RSP1A and RSP2B).
I will be very thankful.
