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 apply the list to a particular neighbor.
There are two kinds of community-lists: expanded and standard. The standard
community-list defines the community attributes as explicit values, without
regular expressions. The expanded community-list defines the communities
attributes with regular expressions.
The standard community-list is compiled into binary format and is directly
compared with the BGP communities attribute in the BGP updates. The
comparison is faster than the expanded community-list. Any community value
