Term Definition
Best Routes (High) The number of best routes currently in the routing table. This number only counts the best route to
each destination. The value in parentheses indicates the highest count of unique best routes since
counters were last cleared.
Alternate Routes The number of alternate routes currently in the routing table. An alternate route is a route that was
not selected as the best route to its destination.
Route Adds The number of routes that have been added to the routing table.
Route Modifies The number of routes that have been changed after they were initially added to the routing table.
Route Deletes The number of routes that have been deleted from the routing table.
Unresolved Route The number of route adds that failed because none of the route's next hops were on a local subnet.
Adds Note that static routes can fail to be added to the routing table at startup because the routing
interfaces are not yet up. This counter gets incremented in this case. The static routes are added to
the routing table when the routing interfaces come up.
Invalid Route Adds The number of routes that failed to be added to the routing table because the route was invalid. A log
message is written for each of these failures.
Failed Route Adds The number of routes that failed to be added to the routing table because of a resource limitation in
the routing table.
Reserved Locals The number of routing table entries reserved for a local subnet on a routing interface that is down.
Space for local routes is always reserved so that local routes can be installed when a routing
interface bounces.
Unique Next Hops The number of distinct next hops used among all routes currently in the routing table. These include
(High) local interfaces for local routes and neighbors for indirect routes. The value in parentheses indicates
the highest count of unique next hops since counters were last cleared.
Next Hop Groups The current number of next hop groups in use by one or more routes. Each next hop group includes
(High) one or more next hops. The value in parentheses indicates the highest count of next hop groups
since counters were last cleared.
ECMP Groups The number of next hop groups with multiple next hops. The value in parentheses indicates the
(High) highest count of next hop groups since counters were last cleared.
ECMP Groups The number of next hop groups with multiple next hops.
ECMP Routes The number of routes with multiple next hops currently in the routing table.
Truncated ECMP The number of ECMP routes that are currently installed in the forwarding table with just one next
Routes hop. The forwarding table may limit the number of ECMP routes or the number of ECMP groups.
When an ECMP route cannot be installed because such a limit is reached, the route is installed with
a single next hop.
ECMP Retries The number of ECMP routes that have been installed in the forwarding table after initially being
installed with a single next hop.
Routes with n Next The current number of routes with each number of next hops.
