For a device with high performance, you can set a high BGP route sending rate as needed. For a
device without high performance, set a relatively low BGP route sending rate as a best practice.
This task applies only to IPv4 unicast routes and IPv6 unicast routes.
To set the BGP route sending rate:
Step
1.
Enter system view.
2.
Enter BGP instance view.
3.
Set the BGP route sending
rate.
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
1.
Enter system view.
2.
Enter BGP instance view.
3.
Configure BGP to delay
sending route updates on
reboot.
4.
(Optional.) Configure BGP to
immediately send route
updates for routes that
match a prefix list.
Configuring a startup policy for BGP route updates
About startup policy for BGP route updates
Perform this task to configure BGP to send route updates with the specified attributes within the
specified period after reboot.
As shown in
completes, traffic sent from Router A through Router B might be lost. This feature enables Router B
to send route updates with the specified attribute values within the specified period after reboot, so
that Router A can forward traffic through Router C.
