Set this object to true if the deprecated-dynamic-capability-
negotiation capability should be advertised to this peer. Even if this
object is set to true, BGP may decide not to advertise the
deprecated-dynamic-capability-negotiation capability to this peer (for
example when it is detected that the peer does not support capability
negotiation or when it is detected that the peer does not support the
deprecated-dynamic-capability-negotiation capability and incorrectly
sends an unsupported capability notification). The
juniBgpPeerSentCapabilityOldDynamicCapabilityNeg can be used to
determine whether or not the capability was actually advertised to the
peer.
