Usage Guidelines
•
KEEPALIVE messages do not contain route updates or indicate a change in the status of the BGP peer;
they indicate to the receiving BGP peer that the connection is still live and the peer is reachable.
•
By default, the KEEPALIVE interval of 30 seconds is one-third the default hold time interval of 90
seconds. The KEEPALIVE interval can never be more than one-third the value of the hold time inter-
val. When the hold time interval is reached without receiving KEEPALIVE or other updates messages,
the peer is considered dead.
•
Setting the KEEPALIVE value to zero means no KEEPALIVE 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.
•
The hold timer is used during the connection setup process and for on-going connection maintenance
with BGP peers. If the peer does not receive a KEEPALIVE, UPDATE, or NOTIFICATION message
within this time period, then the BGP connection will be closed.
•
Both the KEEPALIVE and hold time interval should be set at the same time.
•
Using this command without the variables resets the variables to their default value.
