peer ignore (BGP-VPN instance IPv4 address family view)

Usage Scenario

When a BGP device needs to transitorily close the session with a peer and reconfiguring the peer requires too much workload, the peer ignore command can be used to avoid the reconfiguration of the peer. For example, if the peer relationship frequently alternates between Up and Down because of the upgrade of a peer or the adjustment of the link, the BGP peer relationship needs to be interrupted temporarily. In this case, the peer ignore command can be used on the stabler end to prevent frequent flapping of the route or peer relationship.

The peer ignore command is used to tear down sessions between a BGP device and its peer and delete all related routing information. In the case of a peer group, a large number of sessions are suddenly torn down.

Configuration Impact

After the peer ignore command is run on a device, the session between the device and its peer is closed and all the related routing information is cleared.

After a BGP session is successfully established, running the peer ignore command interrupts the BGP session. The interrupted BGP session cannot be established again, and the status of the corresponding BGP peer relationship is displayed as Idle.
