As OSPF supports broadcast domain and mobility LTE standard requests S1 to X2 handover, that makes many wireless SPs choose OSPF to build back haul network. Given the size of back haul network, any advanced technology help to scale up the deployment are welcome.

I support it as a co-author. It allows us to turn network zones into virtual entities and thus increases the network scalability. The implementation of this method in our operating system has shown that it works great, especially for those very complex network topologies.

This is the start of the WG last call for the “OSPF Topology Transparent Zone” protocol extensions draft. We’ve had a number of discussions on this and Huawei has a prototype implementation. The WG last call will end at
12:00 AM PDT on February 1st, 2016. For your convenience, here is a URL:
