as the number of routes of each type, are not reset.

Default None
Mode Privileged EXEC
6.2.1.16. show ip route preferences
This command displays detailed information about the route preferences. Route preferences are used in
determining the best route. Lower router preference values are preferred over higher router preference values.
Hardware Failed Route Adds
The number of routes failed to be inserted into the hardware because of 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 the local
routes can be installed when a routing interface is up.
Unique Next Hop (High)
The number of the distinct next hops used among all routes currently in the
routing table. This number includes local interfaces for local routes and neighbors
for indirect routes. The value in the parentheses indicates the highest count of
unique next hops after 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 the parentheses indicates
the highest count of next hop groups after counters were last cleared.
ECMP Groups (High)
The number of next hop groups with multiple next hops. The value in the
parentheses indicates the highest count of next hop groups after 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 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 Hop
The current number of routes with specific number (n) of next hops.
