Set this object to true if the 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
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
dynamic-capability-negotiation capability and incorrectly sends an
unsupported capability notification). The
juniBgpPeerSentCapabilityDynamicCapabilityNeg can be used to determine
whether or not the capability was actually advertised to the peer.
