BGP for Dynamic Interfaces

BGP is supported over dynamic PPPoE interfaces with PPPoE subscriber clients corresponding to BGP neighbors. Configure the PPPoE subscriber client IP addresses as the BGP neighbor addresses. BGP over dynamic interfaces requires routing services to be enabled in both the PPPoE subscriber dynamic profile and the dynamic profile for the underlying VLAN interface with the routing-service statement. The routing-service statement replaces the deprecated routing-services statement. Routing services can be selectively enabled or disabled per subscriber through RADIUS by with $junos-routing-services predefined variable. The action is determined by the value of the new Routing-Services VSA (26-212) returned in the RADIUS Access-Accept message.
