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 | ipv6 } unicast
4. nexthop trigger-delay { critical delay | non-critical delay }
5. commit
