Modify the Hold-Time Value

The hold time is the maximum number of seconds allowed to elapse between the time that a BGP system receives successive keepalive or update messages from a peer. When establishing a BGP connection with the local router, a peer sends an open message, which contains a hold-time value. BGP on the local router uses the smaller of either the local hold-time value or the peer's hold-time value received in the open message as the hold time for the BGP connection between the two peers.

The default hold-time value is 90 seconds.

To modify the hold-time value on the local BGP system, include the hold-time statement:

hold-time seconds; 

You can configure the hold-time value globally for all BGP groups (at the [edit protocols bgp] hierarchy level), for all peers in a group (at the [edit protocols bgp group group-name] level), or for an individual peer (at the [edit protocols bgp group group-name neighbor address] level). For routing instances, include the statement at the [edit routing-instances routing-instance-name protocols bgp] hierarchy level and the [edit routing-instances routing-instance-name protocols bgp group group-name neighbor address] hierarchy level.

The hold time is three times the interval at which keepalive messages are sent.
