Configuring BGP route update delay
Perform this task to configure BGP to delay sending route updates on reboot to reduce traffic loss. With this feature enabled, BGP redistributes all routes from other neighbors on reboot, selects the optimal route, and then advertises it.
To configure BGP route update delay:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter BGP instance view. | bgp as-number [ instance instance-name ] | N/A |
3. Configure BGP to delay sending route updates on reboot. | bgp update-delay on-startup seconds | By default, BGP immediately sends route updates on reboot. |
4. (Optional.) Configure BGP to immediately send route updates for routes that match a prefix list. | bgp update-delay on-startup prefix-list prefix-list-name | By default, no prefix list is specified to filter routes. Use this command when the updates for the specified routes must be sent immediately. This command is available only to IPv4 prefix lists. |
