Enables load sharing if multiple routes to the same destination are available. When multiple routes to the same destination are available, load sharing can be enabled to distribute the traffic to multiple destination gateways. Only paths with the same lowest cost are shared.
|vrname||VR or VRF name for which IP route sharing is being enabled.|
IP route sharing allows multiple equal-cost routes to be used concurrently. IP route sharing can be used with static routes or with OSPF, BGP, or IS-IS routes. In OSPF, BGP, and IS-IS, this capability is referred to as ECMP routing.
Configure static routes and OSPF, BGP, or IS-IS as you would normally. The ExtremeXOS software supports route sharing across up to 64 way ECMP for OSPFv2, BGP, and static routes, or up to 64-way ECMP for OSPFv3 and 8 way for ISIS. However, on SummitStack, and ExtremeSwitching series switches, by default, up to four routes are supported. To support 2, 4, 8, 16, 32, or 64 routes on these switches, use the following command:configure iproute sharing max-gateways max_gateways
If a VR is not specified, this command enables IP route sharing in the current VR context.
The following example enables load sharing for multiple routes:
enable iproute sharing
This command was first available in ExtremeXOS 11.1.
The vr option was added in ExtremeXOS 12.5.
The ipv6 option was first available in ExtremeXOS 15.3.
This command is available on the ExtremeSwitching X450-G2, X460-G2, X465, X590, X620-x, X695 series switches.
