Mode Global Configuration
Usage A community-list can be used as a filter to BGP updates. Use this command to define
the community access list globally, then use neighbor configuration commands to

list defines the community attributes explicitly and not via a regular expression. An
expanded community-list defines the communities attributes with regular expressions.
