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.
