track route-monitor-group

Function

The track route-monitor-group command enables the network-side device to track the status of a route group and configures a link failure ratio threshold for triggering a master/slave switchover.

The undo track route-monitor-group command disables the network-side device from tracking the status of a route group and deletes the configured link failure ratio threshold for triggering a master/slave switchover.

By default, the network-side device is disabled from tracking the status of a route group and deletes the configured link failure ratio threshold for triggering a master/slave switchover.

This command is supported only on the NetEngine 8000 F1A.

Format

Usage Guidelines

Usage Scenario

To enable the network-side device to track the status of a route group, run the track route-monitor-group switchover failure-ratio command. When the link on the network-side device fails, terminals cannot access the network. If the device is deployed on the network-side device, tracking interfaces cannot implement end-to-end detection between the NetEngine 8000 F and core router. If BFD is used, devices must support BFD. Tracking IGP routes is easy to implement. When hot backup is deployed, a device must monitor the status of the IGP route on the network-side device. If the IGP route fails, a master/slave switchover is triggered on the access side, ensuring that terminals can properly access the network.

Generally, multiple links are deployed on the network-side device. If some links fail, downstream traffic may be congested. In this situation, a master/slave switchover must also be promptly triggered on the access side.

Configuration Impact

After you run the track route-monitor-group switchover failure-ratio command in the remote backup service view in which the track interface command has been run, the device automatically deletes the track monitor-group and switchover uplink configurations and then controls service switchover based on the track route-monitor-group switchover failure-ratio configuration.
After you run the track route-monitor-group switchover failure-ratio command in the remote backup service view, you can no longer run the track interface or switchover uplink command.

Precautions

In VS mode, this command is supported only by the admin VS.

You can configure a remote backup service view to simultaneously track two interface groups and two route groups. If an interface or route group meets switchover conditions, a switchover is triggered. A switchback can be triggered only when all interface or route groups recover and meet switchback conditions.

Example

# Configure the remote backup service named rbs to track the route group.
