Configuring BGP Route Recursion to the Default Route

When the next hop of a BGP route is not directly reachable, you can configure BGP route recursion to the default route.

Usage Scenario

The next hops of BGP routes may not be directly reachable. In this case, recursion is required so that the BGP routes can be used for traffic forwarding. You can configure whether to allow BGP routes to recurse to the default route.

Pre-configuration Task

Before configuring BGP route recursion to the default route, configure basic BGP functions.

Procedure

Run system-view
The system view is displayed.
Run bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
Run ipv4-family unicast
The BGP-IPv4 unicast address family view is displayed.
Run nexthop recursive-lookup default-route
BGP route recursion to the default route is configured.
Run commit
The configuration is committed.

Verifying the Configuration

After configuring BGP route recursion to the default route, run the display current-configuration command in the system view to check whether the function is configured.
