Adjusting BGP Timers Example
1. Configure a BGP neighbor as in the “BGP Neighbors Example.”
2. Click the link for the peer IP address to configure peer-specific parameters.
3. Enter a value in seconds in the Holdtime text box.
Holdtime indicates the maximum number of seconds that can elapse between the receipt of
successive keepalive or update messages by the sender before the peer is declared dead. It
must be either zero (0) or at least 3 seconds.
The default value is 180 seconds.
4. Enter a value in seconds in the Keepalive text box; then click Apply.
BGP does not use any transport-protocol-based keepalive mechanism to determine whether
peers are reachable. Instead, keepalive messages are exchanged between peers to determine
whether the peer is still reachable.
