Mode
A community-list can be used as a filter to BGP updates. Use this command to define the
Usage
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 that does not match the standard community value is
automatically treated as expanded.
