This field is used in conjunction with the bgpPeerSendExtComm field in the bgpPeerTable to indicate whether BGP will send UPDATE messages to the peer for this address family containing BGP extended community attributes. When set to 'true', and bgpPeerSendExtComm is set to 'true', DC-BGP sends UPDATE messages to the peer for this address family including BGP extended community attributes. Otherwise, DC-BGP sends UPDATE messages to the peer, for this address family omitting BGP extended community attributes. Changing the value of this field while the peer is active triggers DC-BGP to resend routes with extended community attributes included or omitted according to the new configuration. The peer may be configured to ignore this field and instead obtain the value from a peer-group as explained in the table description.
