Mode
A community-list can be used as a filter to BGP updates. Use this command to define
Usage
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. A standard
community-list defines the community attributes explicitly and not via a regular
expression. An 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 that does not match the standard community value is
automatically treated as expanded.
