Field Description

IP address

IP address reachable via the interface

Interface

Interface type and specifier associated with the IP address; displays “Local Interface” if a special interface index is present in the routing table for special IP addresses, such as broadcast addresses

Next Hop

IP address of the next-hop router to reach the IP address; displays “---” if no next hop is associated with the IP address; displays “Down” if the ECMP set for a specific route on a slot is down
