Thanks for your reply Pshem. We have one question after reading your post; are you using WANPHY with transmission electronics ( like DWDM ) in-between or it is just across the a dark fiber cable. Regards Amos

Due to protection, we have recently added another 10Gbps link connecting 2 Cisco CRS-3 core routers, namely CR-A and CR-B. The config below are on CR-A and CR-B has similar config. Question : 1. Is this a known issue that BE interface does not support BFD ? 2. Without BFD link failure detection at ISIS level is going to be slower and we perceive that the convergence speed will fall back to ISIS native convergence speed ? 3. Is (2) the worst case and or is there any else that tend to fail ? We are looking forward to any members who has this environment to share their experience in this area. Thanks. Not exactly CRS-3, but in one deployment of ASR9k with Eth-Bundles we've used both WANPHY and OTU2e in order to speed up link error detection. From what we've gathered for single (non-bundle) links WANPHY and OTN2e is always faster and what's more important can start the switchover when errors reach certain level, not after the link failed completely. kind regards Pshem _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
