ECMP routing allows multiple entries for routes to the same destination. Each path has the same cost as the other paths, but a different next-hop router. The ip load-sharing
command specifies the maximum number of equal paths that can be configured. Values range from 2 to 4.
Syntax:
When OSPF is enabled and multiple, equal-cost, next-hop routes are available for traffic destinations on different subnets, this feature, by default, enables load-sharing among up to four nexthop routes. The no form of the command disables this loadsharing so that only one route in a group of multiple, equalcost, next-hop routes is used for traffic that could otherwise be load-shared across multiple routes.
(Default: Enabled with four equal-cost, next-hop routes allowed)
Notes: This command enables or disables load-sharing for both IPv4 (OSPFv2) and IPv6 (OSPFv3) operation. For more information on load-sharing in the latest IPv6 Configuration Guide for your routing switch.
In the default configuration, IP load-sharing is enabled by default. However, it has no effect unless IP routing and OSPF are enabled.
