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.
•
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.
•
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.
•
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.
•
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.
