The ip route-monitor-group command creates a route monitoring group and displays the view of this route monitoring group, or displays the view of an existing route monitoring group.
The undo ip route-monitor-group command deletes a route monitoring group.
By default, no route monitoring group is created on a switch.
| Parameter | Description | Value |
|---|---|---|
group-name |
Specifies the name of a route monitoring group. |
The value is a string of 1 to 31 case-sensitive characters. |
Usage Scenario
All network-side routes of the same type can be added to the same route monitoring group, which monitors a certain number of routes. In a hot standby scenario, you can add network-side routes to a route monitoring group and associate access-side service modules with it so that the service modules can perform active/standby link switchovers upon route changes in the group. This mechanism prevents network congestion and packet loss.
Follow-up Procedure
Run the track ip route command to add a route to the route monitoring group.
