+ Alex + <te-topo-model> authors Sue, Jeff,
The authors of the <te-topo-model> draft had a meeting today with one of the authors (Alex) of the <network-topo-model> draft and discussed ways to align the topo models. The consensus so far is that the <te-topo-model> WILL augment the <network-topo-model>. There are some issues that need to be worked out (mapping identifiers, termination-points), but those should get resolved in due course of time. I'll sync up with you (Sue) and coordinate a meeting between the authors of the <te-topo-model> and the authors of the I2RS topo model(s) at the IETF --- hopefully early in the week.
