DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Command Default Level Level: 12. Usage Guideline The extended community attribute is used for implementing policy routing. It is an optional, transitive attribute and facilitates transfer of local policies through different autonomous systems. All the names of the standard extcommunity list and expanded extcommunity list must not be the same. This command can be applied multiple times. BGP extended community attributes exchanged between BGP peers are controlled by the neighbor send-community command. If permit rules exist in an extended community list, routes with extended community that does not match any rule in the list will be denied. If there are no rules or only deny rules to be configured in the extended community list, all routes will be denied. Example This example shows how to define a standard extended community list named "myecom" with an entry. Switch# configure terminal Switch(config)# ip extcommunity-list standard myecom permit rt 1:1 soo 1.1.1.1:1 This example shows how to create an expanded extended community list named "myexpcom" with an entry.
