BGP Extended Community List Settings

This window is used to view and configure the BGP feature's extended community list settings. 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 extended community list and expanded extended community list must not be the same.
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.
