ROUTE-MAP PROCESSING METHOD AND PROVIDER EDGE DEVICE

摘要

The invention provides a route-map processing method and a Provider Edge (PE) device. A first interface of a PE device is connected to a first Virtual Private Network (VPN), and a second interface of the PE device is connected to a second VPN. The method comprising: configuring a forward route-map from the first VPN to the second VPN for the first interface; the second interface generating a reverse route-map according to the forward route-map obtained from the first interface, or, the first interface generating a reverse route-map according to the configured forward route-map and announcing the generated reverse route-map to the second interface. The invention reduces the complexity of the route-map maintenance process.
