Set this object to true if the four-octet-as-numbers capability should
be advertised to this peer. Even if this object is set to true, BGP may
decide not to advertise the four-octet-as-numbers 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 four-octet-as-numbers capability and incorrectly sends an
unsupported capability notification). The
juniBgpPeerSentCapabilityFourOctetAsNumbers can be used to determine
whether or not the capability was actually advertised to the peer.
