Hi, Samier:
L2 topo is used to describe neighbor relationship and can be collected by LLDP or any other Layer 2 protocol, are you sure LDP protocol should be part of L2 topo model? If there is a use case for LDP, L2 topo model could be augmented in the separate model to support such use case.
BTW, L2 topo has completed WGLC. The token is in the document shepherd’s hand.

Hello authors,

We have been using your model to describe our L2 Topology in a single domain IP scenario. During the last month we have been exporting this topology to a centralized entity in order to build a multi-domain (two IP domain controllers) L2-Topology. However, In order to build this end-to-end L2 view of our networks we were expecting to use the LDP neighbour relationship, however in the draft-ietf-i2rs-yang-l2-network-topology there is not such possibility.

Do you have any plan to include this information in the model? If not how do you expect a centralized entity (Network Orchestator) can build an end-to-end L2 view of the network if the L2 Topo is reported by two domain controllers?

Thanks in advance for your answer.
