show ip route forward

Displays routes stored in the Forwarding Information Base (FIB).

show ip route forward [ ipv4net ]

Displays routes stored in the FIB.

ipv4net
Optional. A route for which information from the kernel forwarding table is displayed.

Operational mode

Use this command to display routes that are stored in the FIB.

The FIB contains multiple equal-cost paths, if they exist. Multiple equal-cost paths are needed before equal-cost multipath (ECMP) routing or WAN load balancing is performed.

The following example shows how to display routes stored in the FIB.
