configure iproute add [<ipNetmask> | <ip_addr> <mask>] <gateway> {metric} 

{multicast | multicast-only | unicast | unicast-only} {vr <vrname>}

A static route’s nexthop (gateway) must be associated with a valid IP subnet and cannot use 
the same IP address as a local VLAN. An IP subnet is associated with a single VLAN by its IP 
address and subnet mask. If the VLAN is subsequently deleted, the static route entries using 
that subnet must be deleted manually.

Configuring the Relative Route Priority

To change the relative route priority, use the following command:

configure iproute {ipv4} priority [blackhole | bootp | ebgp | ibgp | icmp | isis 

| isis-level-1 | isis-level-1-external | isis-level-2 | isis-level-2-external | 

ospf-as-external | ospf-extern1 | ospf-extern2 | ospf-inter | ospf-intra | rip 

| static] <priority> {vr <vrname>}

Configuring Hardware Routing Table Usage

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 

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> }

Configuring IP Route Sharing

IP route sharing is introduced in 

on page 598. The following 

sections describe how to manage IP route sharing:

•     Managing IP Route Sharing on NETGEAR 8800 Switches 

•     Viewing the IP Route Sharing Configuration 

Using IP route sharing makes router troubleshooting more difficult 

because of the complexity in predicting the path over which the 
traffic travels.
