Community List

Use a community list to

Create groups of BGP communities to use in a match part of a route map.
Control which routes are accepted, preferred, distributed, or advertised.
Set, append, or modify the communities of a route.

Following are the three types of community list which SLX supports.

Standard: 4 bytes BGP community
Extended: 8 bytes BGP community
Large: 12 bytes BGP community

EFA supports configuration of standard and extended community list. You can create, delete, update, and list standard and extended community list on a set of devices in fabric.

Create and update operations support rollback. If a configuration on one device fails, the configuration is rolled back on devices that were successfully configured. This ensures the consistent configuration of policies across all devices.

Delete operations do not support rollback. As a best practice, remove the configuration. If removing configuration on a device fails, the command will display an error for that device. The configuration that was removed successfully on other devices, will not be added back.
