A router is configured to send an advertisement of selective Ethernet Virtual Private Network (VPN) (EVPN) routes based on the Route Types. The router is configured to determine a requirement for a route refresh from a Border Gateway Protocol (BGP) peer for a subset of Route Types of all of the Route Types, send a route refresh message to the BGP peer with an indication of the subset of Route Types, and receive updated routes from the BGP peer only for the subset of Route Types. The indication can be included in a reserved field and payload of the route refresh message. The route refresh message can be defined in RFC 2918.

Advertisement of selective EVPN routes based on route types

Aspects of the subject disclosure may include, for example, a first BGP device establishing a BGP session between the first BGP device and a second BGP device, generating an identifier associated with the second BGP device during establishment of the BGP session, receiving route advertisements from the second BGP device, associating the identifier with the route advertisements, and providing the identifier with the route advertisements to a third BGP device. Other embodiments are disclosed.
