NETGEAR 8800 User Manual configure iproute add [ | ] {metric} {multicast | multicast-only | unicast | unicast-only} {vr } 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] {vr } 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 Hardware Routing Table Management on page 604. To configure the number of IP routes to reserve in the LPM hardware table, use the command: configure iproute reserved-entries [ | maximum | default ] slot [all | ] To display the current configuration for IP route reserved entries, use the command: show iproute reserved-entries {slot } To display the hardware table usage for IP routes, unicast and multicast, use the command: show iproute reserved-entries statistics { slot } Configuring IP Route Sharing IP route sharing is introduced in IP Route Sharing and ECMP on page 598. The following sections describe how to manage IP route sharing: • Managing IP Route Sharing on NETGEAR 8800 Switches on page 614 • Viewing the IP Route Sharing Configuration on page 614 Note: Using IP route sharing makes router troubleshooting more difficult because of the complexity in predicting the path over which the traffic travels.
