In the case of EVPN symmetric routing, the tenant VRF is associated with a VNI that is used for routing and commonly referred to as the L3 VNI or VRF VNI. Corresponding to this VNI is a VLAN and its associated L3 (IP) interface (SVI). Overlay next hops (i.e., next hops for routes in the tenant VRF) are reachable over this interface. https://tools.ietf.org/html/draft-ietf-bess-evpn-prefix-advertisement section 4.4 provides additional description of the above constructs. The implementation currently derives this L3 interface for EVPN tenant routes using special code that looks at route flags. This patch exchanges the L3 interface between zebra and bgpd as part of the L3-VNI exchange in order to eliminate some this special code.
