Usage Guidelines

Usage Scenario

Community attributes are BGP-specific and are used to simplify routing policy application and network maintenance and management. A community is a set of destination addresses with the same characteristics. These addresses have no physical boundary and are independent of their ASs. They share one or multiple community attributes. To configure community attributes for a BGP community list, run the community command.

Example

# Configure a community attribute named 123 for the BGP community list named community1.

<HUAWEI> system-view
[~HUAWEI] ip community-list community1
[*HUAWEI-community-list-community1] community 123
