Usage Guideline
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. A community attribute is
represented by a 32 bits integer. If no community value is associated with a path, by default, the Internet
community is associated with the path.
A community list can contain multiple rule entries, either as a deny entry or a permit entry. Use the
command to define a community list rule entry.
A community list can be either a standard community list or an expanded community list. The rule entry
defined in a standard community list contains a string formed by a number of communities, separated by
space. The rule entry defined in an expanded community list contains a regular expression.
Use the match community command to match a community list in a route map entry definition. To match
a route map entry, all match statements must be satisfied. To match a community list, if an entry in the
community list matches the route, then no further check will be done against the remaining entries in the
access list. If the matched entry is a permit entry, then the community list is matched. If the matched entry
is a deny entry, then the community list is not matched. If none of the rule entries in the community list
match the route, then the community list is not matched.
Example
Specifies to configure a named standard community list.
Specifies to configure a named expanded community list.
Specifies the community list name. The maximum length is 16 bytes.
Specifies that routes that match the rule entry are permitted.
Specifies that routes that match the rule entry are denied.
(Optional) Specifies the community is a 32-bits integer. It can be a
user-specified number represented by AA:NN, where AA (AS number)
is the upper part of the word and NN (community number, user-
specified) is the lower part of the word. Multiple numbers (separated by
comma) can be specified.
(Optional) Specifies the well-known community by using the following
keywords. Multiple numbers (separated by space) can be specified.
internet - Specify routes free to be advertised to all peers.
local-as - Specify not to send out of the local AS or sub autonomous
system of a confederation.
no-advertise - Specify not to advertise the route to other BGP peers.
no-export - Specify not advertise to external peers.
Specifies to configure a regular expression that is used to specify a
pattern to match against an input string. Note: Regular expressions
can be used only with expanded community lists.
