11.1.6 BGP Community List
The community-lists specify BGP community attributes. The community attribute is used
for implementing policy routing. It is an optional, transitive attribute and facilitates transfer
of local policies through different autonomous systems (ASs). It includes community
values that are 32 bits long.
There are two kinds of community-lists: the expanded and standard. The standard
community-list defines the community attributes in a specified format and not with regular
expressions. The expanded community-list defines the community attributes with regular
expressions.
Use the ip community-list standard command to add a standard community-list entry.
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.
To add a community list entry, use the following command.
