When the maximum number of routes is not configured, the CAM can hold a maximumECMP per route.Use the ip ecmp-group path-fallback command to enable or disable the feature.pt-s4801-temp1(conf)#ip ecmp-group maximum-paths 3User configuration has been changed.

The system can generate a maximum of 512 uniqueecmp-groups. The ecmp-group indexes are generated in even numbers (0, 2, 4, 6... 1022) and are forinformation only.For link bundle monitoring with ECMP, the ecmp-group command is used to enable the link bundlemonitoring feature. The ecmp-group with id 2, enabled for link bundle monitoring is user configured. Thisis different from the ecmp-group index 2 that is created by configuring routes and is automaticallygenerated.These two ecmp-groups are not related in any way.Task Command Syntax Command ModeConfigure the maximum number of pathsper ECMP groupip ecmp-group maximum-paths{2-64}CONFIGURATIONEnable ECMP group path management ip ecmp-group path-fallback CONFIGURATIONNote: You must save the new ECMP settings to the startup-config (write-mem) then reload the system for thenew settings to take effect.
