Configuration Guide - IP Unicast Routing

S7700 and S9700 V200R011C10

This document describes IP Unicast Routing configurations supported by the switch, including the principle and configuration procedures of IP Routing Overview, Static Route, RIP, RIPng, OSPF, OSPFv3, IS-IS(IPv4), IS-IS(IPv6), BGP, Routing Policy ,and PBR, and provides configuration examples.

Configuring Equal-Cost Routes

Configuring Equal-Cost Routes


If the destinations and costs of the multiple routes discovered by one routing protocol are the same, load balancing can be implemented among the routes.

As shown in Figure 5-68, three routes between switchA and switchB that run OSPF have the same costs. The three routes are equal-cost routes for load balancing.

Figure 5-68  Networking diagram of equal-cost routes


  1. Run system-view

    The system view is displayed.

  2. Run ospf [ process-id ]

    The OSPF process view is displayed.

  3. Run maximum load-balancing number

    The maximum number of equal-cost routes is set.

    By default, the maximum number of equal-cost routes is 32.

  4. (Optional) Run nexthop ip-address weight value

    The route preferences are configured for load balancing.

    When the number of equal-cost routes on the live network is greater than that specified in the maximum load-balancing command, valid routes are randomly selected for load balancing. To specify valid routes for load balancing, run the nexthop command to set the route preference. Ensure that the preferences of valid routes to be used are high.

    The smaller the weight value, the higher the preference of the route. The default weight value is 255, which indicates that load balancing is implemented regardless of the route preferences.
