Hi everyone, Anybody from Yahoo to share experience on IGP choice ? IS-IS vs OSPF, why did you switch from one to the other, for what reason ? Same question could apply to other ISP, I'd like to heard some international ISP/carriers design choice, please. Thank in advance, Best regards, -Marcel
When we decided to go dual-stack many many years ago, we faced the choice of either running OSPFv2 and OSPFv3 in parallel in the core, or just running IS-IS. Several of us on the team had experience with IS-IS from previous jobs, so we decided to shift over from OSPF to IS-IS to simplify the environment by only needing a single IGP for both address families. Hope this helps answer your question. Thanks! Matt
