Usage Guidelines
• Configures the time interval between KEEPALIVE messages sent by this peer. KEEPALIVE messages
do not contain route updates or indicate a change in the status of the BGP peer; they serve only to tell
the receiving BGP peer that the connection is still live and the peer is reachable.
the receiving BGP peer that the connection is still live and the peer is reachable.
• By default, the keep alive interval of 30 seconds is one-third the default hold-time interval of 90
seconds. The keep alive interval can never be more than one-third the value of the hold-time interval.
When the hold interval is reached without receiving keep alive or other updates messages, the peer is
considered dead.
When the hold interval is reached without receiving keep alive or other updates messages, the peer is
considered dead.
• Setting the keep alive value to zero means no keep alive messages will be sent.
• Once a connection is established with a peer and a time period of the length specified in this command
transpires with no messages from the remote peer, then the connection with that remote peer will be
considered dead.
considered dead.
• Configures the tolerated hold time interval, in seconds, for messages to this peer from other peers. The
hold timer is used during the connection setup process and in on-going connection maintenance with
BGP peers. If this peer does not receive a KEEPALIVE, UPDATE, or NOTIFICATION message
within this time period, then the BGP connection will be closed.

within this time period, then the BGP connection will be closed.
• By default, the hold-interval of 180 seconds is three times the default keep-alive interval of 60 seconds.
The hold-interval can never be less than three times the keep-alive value.
