Configuring BGP Next Hop Trigger Delay
Perform this task to configure BGP next-hop trigger delay. The Routing Information Base (RIB) 
classifies the dampening notifications based on the severity of the changes. Event notifications are 
classified as critical and noncritical. This task allows you to specify the minimum batching interval for 
the critical and noncritical events.
SUMMARY STEPS
1. configure 
2. router bgp as-number 
3. address-family {ipv4 unicast | ipv4 multicast | ipv4 tunnel | ipv4 mdt | ipv6 unicast | ipv6 
multicast |vpnv4 unicast | vpnv6 unicast}
4. nexthop trigger-delay {critical delay | non-critical delay} 
5. end
or
commit
Step 7
route-policy 
route-policy-name
 {in | out} 
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# 
route-policy drop-as-1234 in
Applies the specified policy to inbound routes.
Step 8
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# end
or
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# commit
Saves configuration changes.
• When you issue the end command, the system prompts 
you to commit changes:
Uncommitted changes found, commit them before 
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the 
running configuration file, exits the configuration 
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and 
returns the router to EXEC mode without 
committing the configuration changes.
–
Entering cancel leaves the router in the current 
configuration session without exiting or 
committing the configuration changes.
• Use the commit command to save the configuration 
changes to the running configuration file and remain 
within the configuration session.
