Usage Guidelines
Usage Scenario
The peer advertise-ext-community command is used to enable a device to advertise an extended community attribute to a specified peer or peer group. If a device advertises an extended community attribute to a specified 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 extended community attribute has been defined in a routing policy.
