Explanation

The EVPN control plane advertises the following types of information: Route type 1 – This is an Ethernet Auto-Discovery (EAD) route type used to advertise Ethernet segment identifier, Ethernet Tag ID, and EVPN instance information. EAD route advertisements may be sent for each EVPN instance or for each Ethernet segment. Route type 2 – This advertises endpoint reachability information, including MAC and IP addresses of the endpoints or VTEPs. Route type 3 – This performs multicast router advertisement, announcing the capability and intention to use ingress replication for specific VNIs. Route type 4 – This is an Ethernet Segment route used to advertise the Ethernet segment identifier, IP address length, and the originating router's IP address. Route type 5 – This is an IP prefix route used to advertise internal IP subnet and externally learned routes to a VXLAN network.
