If the router does not receive regular BGP keepalive, update or notification messages within the configured BGP short-hold time, the router will terminate the BGP session and send a notification with the error code "Hold Timer Expired".
The device negotiates this value with the BGP neighbors during connection establishment. The lower of the two values is considered to be valid.
Note: If negotiation results in a value of "0", the device considers the connection to be valid until it receives a
connection error or the connection breaks. No keepalive messages are sent to the BGP neighbors during this period, even if the
keepalive timer is set with a value.
Important: In accordance with the RFC, the values "1" and "2" are not permitted.
