Please review and provide feedback. Looks good! Question: why did you unite vlan ID and VRF ID? Aren't they orthogonal things? Observation: the term BIB is defined in RFC6146 but only in the context of NAT64. Yet this draft uses it in the context of NAT44. I foresee problems. For example, it is not clear how a fully symmetric NAT (which has no BIB) would use this. Would it only log session events and never BIB events? Also, what about NATs that don't track sessions? Would they just log BIB events and never session events? What about NAT46 and NAT66? Are they supported? Lastly, I see feature overlap between this draft and the MIB draft for the addresses exhausted, ports exhausted, and quota exceeded event. Do we really want to provide two ways of doing the same thing?
