Time interval in seconds for the KeepAlive timer configured for this
BGP speaker with this peer. The value of this object will only
determine the KEEPALIVE messages' frequency relative to the value
specified in bgpPeerHoldTimeConfigured; the actual time interval for the
KEEPALIVE messages is indicated by bgpPeerKeepAlive. A reasonable
maximum value for this timer would be configured to be one third of that
of bgpPeerHoldTimeConfigured. If the value of this object is zero (0),
no periodical KEEPALIVE messages are sent to the peer after the BGP
connection has been established. The suggested value for this timer is
30 seconds.
