Chapter 9 Recursive Routing Configuration
9.1 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.

Description
By default, both routes learned by
the BGP and static routes support
recursive routing.
