COMMUNITY-LIST EXPANDED
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. 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.
Examples
awplus# configure terminal
awplus(config)# ip community-list 125 permit 6789906
