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 that does not match the standard
community value is automatically treated as expanded.
Parameter Description
<1-99> Standard community list number.
standard Specifies a standard community list.
<standard-listname> Standard community list entry.
deny Specifies community to reject.
permit Specifies community to accept.
<community>{
<AS:VAL>|local-AS|no-advertise|no-export}
<AS:VAL> Specifies the valid value for the community number. This
format represents the 32 bit communities value, where
AS is the high order 16 bits and VAL is the low order 16
bits in digit format.
local-AS Specifies routes not to be advertised to external BGP
peers.
no-advertise Specifies routes not to be advertised to other BGP peers.
no-export Specifies routes not to be advertised outside of the
Autonomous System boundary.
