Field Description
Gateway Displays either the word “direct” and an interface for a directly connected route or the
remote IP address used to forward the traffic.
First-Hop Displays the first hop IP address.
Mac-Addr Displays the MAC address.
Port Displays the egress-port information.
VId Displays the VLAN ID. If no VLAN is assigned, zero (0) is listed.
EC Displays the number of ECMP paths.
If weighted ECMP is enabled, then the show ip fib stack-unit command display a new column named W-
EC (Weighted ECMP). This column displays either a value of
1 or 0 depending on whether or not a route is
assigned with a weight.
Example
DellEMC# show ip fib stack-unit 1
