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 Figure 61, if Router B restarts and sends route updates before route convergence 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.
