Q: What does R represent in the display ip routing-table command output?
A: R represents relay. It indicates that the route is the recursive route. The outbound interface is obtained based on the next hop address of the route.

When a static route is configured, if only the next hop address is specified but the outbound interface is not specified, the route is the recursive route. The outbound interface is obtained based on the next hop address of the route.
BGP routes are recursive routes.
