ExtremeWare XOS 11.5 Command Reference Guide
1394
enable iproute sharing
enable iproute sharing
Description
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 is will be shared.
Syntax Description
This command has no arguments or variables.
Default
Disabled.
Usage Guidelines
IP route sharing allows multiple equal-cost routes to be used concurrently. IP route sharing can be used
with static routes or with OSPF routes. In OSPF, this capability is referred to as
equal cost multipath
(ECMP) routing.
Configure static routes and/or OSPF as you would normally. ExtremeWare XOS supports route sharing
across up to 8 static routes or ECMP routes for OSPF. However, on the BlackDiamond 8800 family and
Summit X450 switches, by default, up to 4 routes are supported. To support up to 8 routes on these
switches, use the following command:
configure iproute sharing max-gateways <max_gateways>
Using route sharing makes router troubleshooting more difficult because of the complexity in predicting
the path over which the traffic will travel.
Example
The following command enables load sharing for multiple routes:
enable iproute sharing
