1716 ExtremeWare 7.7 Command Reference Guide
IP Unicast Commands
disable iproute sharing
disable iproute sharing

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
Enabled
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. ECMP is not disabled when you disable ip-route sharing. By default, ECMP can
load-balance on up to four next-hops, irrespective of the route-sharing configuration.
Configure static routes and/or OSPF as you would normally. ExtremeWare supports unlimited route
sharing across static routes and up to 12 ECMP routes for OSPF.
Route sharing is useful only in instances where you are constrained for bandwidth. This is typically not
the case using Extreme switches. 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 disables load sharing for multiple routes:
disable iproute sharing
