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 Rotue Adds
The number of routes 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.
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.
Kernel Failed Route Adds
The number of routes that failed to be added to the routing table by kernel
because of a resource limitation in the routing table.
Hardware Failed Route Adds
The number of routes that failed to be inserted into the hardware due to a hash
error or a table full condition.
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. The (High) means the highest count of uniqe next hops since counters
were last cleared. 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. The (High) means the highest count
of next hop groups since counters were last cleared.
ECMP Groups (High)
The number of next hop groups with multiple next hops. The (High) means the
highest count of next hop groups with multiple next hops since counters were
last cleared.
ECMP Routes
The number of routes with multiple next hops currently in the routing table.
Truncated ECMP Routes
The number of ECMP 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 a ECMP route cannot be installed
because such a limit is reached, the route is installed with a single next hop.
