H3C IE4300 Command Reference Manual page 1479

Usage guidelines
This command makes a routing policy take effect after a delayed time interval, which prevents
incomplete routing policy configuration from being issued to cause incorrect route advertisement.
The system automatically starts the timer when a routing policy changes. The changes will not take
effect on the routing policy until the change delay timer expires.
A routing policy changes when one of the following events occurs:
•
A routing policy is created.
•
A routing policy node, if-match clause, or apply clause is added, modified, or deleted for a
routing policy.
•
An IPv4 prefix list, IPv6 prefix list, AS path list, community list, extended community list, or MAC
list is added, modified, or deleted.
•
The ACL used by an if-match clause changes.
To have enough time to complete routing policy configuration, you can specify the
keyword for the command. Then, execute the
configuration.
If you modify the routing policy change delay timer before it expires, the timer will be reset.
Examples
# Set the routing policy change delay timer to 60 seconds.
