Abstract

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.
