Do we have reason to believe that no one outside the IETF has used ip-address as we published in ways that need a zone? It seems to me that the first step in the plan below is reasonable. But changing ip-address itself seems a bad idea. If one means no-zone, use the -no-zone typedef.

Acee, I am missing something basic. It seems to me that it would be very wrong for the LSR YANG module to demand a change to an important type because it turns out that type doesn't mean what LSR thought it meant. Such an error is LSR's problem, not the underlying modules. There seem to be

If you want to experiment with unusual metrics, and minimize the degree to which you need consistency, maybe you should look at running a different routing protocol in this limited domain? Rather than trying to make IS-IS and OSPF do something they are not designed for? (While there are
