Table 274: Summary Fields (continued)
Field
Description
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 Adds
The number of route adds that failed because none of the route's next hops were
on a local subnet. 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 (High)
The number of distinct next hops used among all routes currently in the routing
table. These include local interfaces for local routes and neighbors for indirect
routes.
Next Hop Groups (High)
The current number of next hop groups in use by one or more routes. Each next
hop group includes one or more next hops.
ECMP Groups (High)
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 Routes
routes that are currently installed
in the forwarding table with just one next 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 Hops
The current number of routes with each number of next hops.
Clear Counters
This button resets to zero IPv4 routing table counters reported in this page. This
only resets event counters. Counters that report the current state of the routing
table, such as the number of routes of each type, are not reset.
