摘要
A method is implemented by a network device to optimize the operation of a virtual private network (VPN) route refresh for border gateway protocol (BGP). The method reduces a span of VPN databases to be traversed to perform a route target constraint (RTC) update at the network device. The method includes receiving an RTC add or delete from a BGP peer, looking up each route target (RT) in a route target-route distinguisher (RT-RD) map to get a set of route distinguishers (RDs), and generating a VPN update for each VPN Address Family (AF) and each RD in the RD cache and sending the VPN update to a respective BGP peer.
