ECMP: Next-hop update rate throttling

You can choose to defer multipath computation for all families during a BGP peering churn. In very large-scale network deployments, during BGP peering churn there is a temporary spike in multipath computation, which takes a toll on the Packet Forwarding Engine resources. This feature allows you to pause the multipath computation and to resume after the peering churn settles down. Note that if there is no BGP peering churn, then multipath computation is not paused. To enable the pause option for BGP multipath computation during BGP peering churn, include the pause computation statement at the [edit protocols BGP multipath] hierarchy level.
