Usage Guidelines
Usage Scenario
The peer advertise-community command is used to configure a device to advertise a community attribute to its peer or peer group. If a device advertises a community attribute to its peer group, all the members of the peer group will inherit the configuration. This simplifies the application of routing policies and facilitates route maintenance and management.
Prerequisites
Peer relationships have been established using the peer as-number command.
A specific community attribute has been defined in a routing policy.
