& Note:
The term “router” or the router icon in this document refers to a router in a generic sense or an S9500 switch running routing protocols.
1.1 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 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.
1.2 Recursive Routing Configuration
Follow these steps to configure recursive routing:

route-rely [ bgp | static ] |
By default, both routes learned by the BGP and static routes support recursive routing. |
& Note:
Currently, only 2-layer recursive routing is supported.
