8.14.5 Configuring the Rate at which BGP Updates Routes in
Response to Non-critical Iteration Changes
You can configure the rate at which BGP updates routes in response to non-critical iteration
changes to prevent BGP from occupying the Central Processing Unit (CPU) resource of other
protocols, reduce CPU loads, and ensure device reliability.
Context
In most cases, BGP routes do not have directly reachable next hops, and route iteration must be
used. When many BGP routes are iterated to one next hop and a non-critical iteration change
occurs on the next hop, such as a change of IGP metric or the number of load balancing routes,
an indirect next hop-enabled device can update forwarding entries rapidly. In this situation, BGP
does not need to update routes one by one, and you can configure the rate at which BGP updates
routes in response to non-critical iteration changes to allow the device to update BGP routes in
the IP routing table gradually. This configuration prevents BGP from occupying the CPU
resource of other protocols, reduces CPU loads, and ensures device reliability.
Pre-configuration Tasks
Before configuring the rate at which BGP updates routes in response to non-critical iteration
changes,
