Since I cannot > currently follow the IDR WG, I don't know what's holding it up right now. There were several issues early on in its development: - Requirements churn. The original request was to bring "configurability" to the MIB. You should find that several of the initial drafts thrashed around configuration objects. Those were dropped ultimately due to both lack of support for it as a feature and resistance from implementors who simply didn't want writeable objects in the MIB. - Structural representations with regard to BGP features that were lists of objects. The usual example that tends to come up for this are communities. The only way to represent communities in a human-readable format is to break them out into a separate table that has a loose relationship to the underlying path attributes table. This is operationally unusable. This particular issue drove me to eventually request the routing and OPS area to request MIB implementors to stop trying to put complex structural encodings in MIBs. There was, IMO, very broad support for this action. The OPS groups at the time recognized that they needed to find a better representational mechanism. I believe netconf/netmod was the general direction such things were pushed. The MIB has been structurally stable for a while and is simply waiting for implementations. I have had one 95% done in Quagga for most of a few years that I simply need to clean up and publish. (And yes, I do recognize the push I've gotten from several individuals in the last year to publish that code. I've simply had other life priorities.) > > Force10 supports it under FORCE10-BGP4-V2-MIB > > Thanks, that's great to know. Force 10 just moved up two notches on > my personal vendor sympathy scale.

And I would appreciate feedback from the implementors with any issues they had with either implementing the MIB from either a structural or an operational standpoint. -- Jeff
