Allowing individual local and remote IPv4 unicast hosts to occupy the
unused portion of the Longest Prefix Match (LPM) table helps reduce Layer 3 hardware hash
table collisions, and reduces slowpath forwarding of IP unicast and multicast traffic. For
more information, see “Hardware Routing Table Management” on page
1262.
-
To configure the number of IP routes to reserve in the LPM
hardware table, use the command:
configure
iproute reserved-entries [ num_routes_needed |
maximum | default ] slot [all | slot_num]
-
To display the current configuration for IP route reserved
entries, use the command:.
show
iproute reserved-entries {slot slot_num}
-
To display the hardware table usage for IP routes, unicast
and multicast, use the command:
show
iproute reserved-entries statistics {slot
slot_num }
