Recursive Routing
Overview
Every route entry must have its next hop address. For a common route, its next
hop address is within the network segment to which the router is directly
connected; for a route requiring recursion, its next hop address is not within the
network segment to which the router is directly connected. During route
forwarding, this non-directly connected next hop address must be
recursion-processed once or several times to find out a directly connected next
hop address to enable L2 path searching. A recursive route can be a static route or
BGP route. Recursive routing can make route entries flexible, independent of a
specific interface.
