Hi Acee, >> Commenting specifically on the OSPF case, when you have such misconfigured >> MTUs, this manifests as weird protocol hiccups.B You don't so much detect >> that there's an MTU issue - you just see OSPF failing to make progress. > > However, when implementations start supporting ietf-ospf.yang, there?ll be an > if-config-err notification specifically indicating an MTU-mismatch. ;^) As mentioned previously, the issue that we are trying to address is where there's no issue with OSPF MTU config, but the WAN circuit fails to carry traffic up to the configured MTU. For example, in last 2 weeks, we have 2 such issues, one with major Tier 1 provider in US and another one with Tier 1 provider in Europe, where OSPF was humming along fine, the circuits could carry 1500 byte payload but not 1512 byte payload. This caused intermittent issue to our end user traffic that traversed these links and not desirable. This is a fault situation - the circuit should not be put in production. We have redundant circuits and would want to divert traffic from these links automatically (hence this draft). Thanks Albert.
