Controlling the Valid Time of Routing Policies
To ensure network stability, you need to configure the delay in applying a routing policy when modifying the routing policy.
Procedure
- Run system-view
The system view is displayed.
- Run route-policy-change notify-delay delay-time
The delay in applying the routing policy is set.
The value ranges from 1 to 180, in seconds.
By default, the RM immediately instructs protocols to apply a new policy when the existing routing policy changes.
- Run quit
Return to the user view.
- (Optional) Run refresh bgp all { export | import }
BGP is configured to apply the new routing policy.
After a routing policy is configured, to make policy-based filtering take effect immediately, use this command to configure BGP to apply the new policy immediately.
The policies affected by the timer are ACLs, IP prefix lists, AS_Path filters, community filters, extended community filters, RD filters, and route-policies.
