Hi Ali and other Co-authors,
In the EVPN IRB draft, Route Type-2 is used to advertise TS's MAC and IP. Two BGP Extended Communities are carried with each RT-2 route. The first community carries tunnel type, the second community carries NVE MAC. In normal case, all RT-2 routes from a remote NVE share same NVE MAC, so in this case the Route information encoding isn't compact. So a new compact encoding method is introduced as follows: 1. Add tunnel type field in Route Type-2. 2. Introduce a new Route Type to exclusively advertise tunnel type,NVE MAC and L3 VN ID. 3. Ingress NVEs correlate the new Type Route and RT-2 routes advertised from egress NVE to get the NVO3 encapsulation information for inter-subnet IP traffic forwarding. Maybe there are other more compact methods. I would like to hear your co-authors opinion on this point. Thanks weiguo
