slow-peer detection disable (BGP-IPv6 MVPN address family view)

Function

The slow-peer detection disable command disables slow peer detection.

The undo slow-peer detection disable command enables slow peer detection.

By default, slow peer detection is enabled, and the slow peer detection threshold is 300s.

Usage Guidelines

Usage Scenario

An update peer-group may consist of multiple BGP peers. If a network problem (congestion for example) occurs and slows down the speed at which the local device advertises routes to a BGP peer in the update peer-group, the speed at which the local device advertises routes to other BGP peers in the update peer-group is affected. To address this problem, run the slow-peer detection command to enable slow peer detection.

After slow peer detection is enabled, the local device calculates the difference between the time taken to send packets to each BGP peer and the shortest time taken to send packets to a BGP peer in the group. If the difference between the time taken to send packets to BGP peer 1 and the shortest time is greater than the threshold, the local device considers BGP peer 1 as a slow peer and removes it from the update peer-group, which prevents this slow peer from affecting route advertisement to other peers in the group.

Configuration Impact

If the command is run more than once, the latest configuration overrides the previous one.

# Disable slow peer detection and set the slow peer detection threshold to 200s.
