Term Definition
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. The value in parentheses indicates the highest count of unique next hops
since counters were last cleared.
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 value in parentheses indicates
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 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.
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 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.
