Configuring BGP update sending delay
Perform this task to configure BGP to delay sending updates on reboot. After this feature is
configured, BGP redistributes all routes from other neighbors on reboot, and then advertises the
optimal route. This configuration reduces traffic loss due to the reboot.
To configure BGP update sending delay:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter BGP view.
bgp
as-number N/A
3. Configure BGP update
sending delay.
bgp update-delay on-startup
seconds
By default, BGP
immediately sends updates
on reboot.
4. Configure BGP to
immediately send updates
for routes that match a
prefix list on reboot.
bgp update-delay on-startup prefix-list
prefix-list-name
By default, BGP delays
sending updates for all
routes on reboot.
Use this command when
updates for routes that
match a prefix list must be
sent immediately.
