Use the no form of this command to delete the community list entry. ip community-list COMMUNITY-LIST-NAME { permit | deny } COMMUNITY no ip community-list COMMUNITY-LIST-NAME [ {permit | deny } COMMUNITY ] Syntax Description COMMUNITY-LIST- Specifies the community list name. The syntax is a general string up to 32 NAME characters in length with no spaces. permit Specifies the community to accept. deny Specifies the community to reject. COMMUNITY This is a user-specified number (32-bits integer) represented by AA:NN, where AA (AS number) is the upper part of the word and NN (community number, userspecified) is the lower part of the word. It can also be one of the following reserved community: internet : Specifies routes. 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 Autonomous System boundary. Default Command Mode Usage Guideline Example BGP community exchange is not enabled by default. It is enabled on a perneighbor basis with the neighbor send-community command. The Internet community is applied to all routes or prefixes by default, until any other community value is configured with this command or the set community command. Global configuration Use the community-lists to 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. It includes community values that are 32 bits long. This command can be applied multiple times. In the command no ip community access-list COMMUNITY-LIST-NAME if a permit or deny keyword is not specified, then all community lists bonded at the specified access list will be removed.
