Hi Qin, I hade made a mistake. I was trying to say LLDP neighbour. A
I will try to explain it again to avoid confusions. As your mentioned the LLDP can be enabled in the network and create the L2 Links (this is our intention). However, We have not seen in the model the way to express this inter-domain neighbourhood, for example: [cid:f7a65f47-0920-41b5-a2d3-db258e8fbb9b] In this network scenario: * Each domain controller will expose a L2 Topology * IP Controller-1 have not in its node DB the Node B * IP Controller-2 have not in its node DB the Node A How the H-SDNc can join the two L2-topo (each from a controller) to generate the common view? It is possible with this 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. -Qin 发件人: SAMIER BARGUIL GIRALDO [mailto:[email protected]] 发送时间: 2020年1月21日 0:36 收件人: [email protected]; [email protected] 抄送: Oscar González de Dios <[email protected]>; Cristian Felipe Rosero Carvajal (COMMS-EGM) <[email protected]> 主题: Mail regarding draft-ietf-i2rs-yang-l2-network-topology 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.
