Extended Match Conditions Configuration > Configuring Communities

A BGP community is a group of destinations that share a common property. Community information is included as a path attribute in BGP update messages. This information identifies community members and allows you to perform actions on a group without having to elaborate upon each member. You can define match conditions based on a BGP community, which this section describes. For information about actions that can be performed on the community, see Table 14.

NOTE: You can assign community tags to non-BGP routes through configuration (for static, aggregate, or generated routes) or an import routing policy. These tags can then be matched when BGP exports the routes.
