L3VPN_1.3.6.1.4.1.2011.5.25.145.33.3 hwIpv4RouteThresholdExceed

Trap Buffer Description

The number of IPv4 routes in the VPN instance exceeded the alarm threshold multiplied by the maximum value. (VPN instance name=[vpnName], number of existing routes=[current], alarm threshold=[midThreshold])

The number of IPv4 routes in the VPN instance exceeded the middle threshold.

Impact on the System

If the number of VPN routes exceeds the alarm middle threshold, excessive routes can still be added to the routing table, and no route loss or traffic interruption occurs at the moment.

Possible Causes

Cause 1: The number of received VPN IPv4 routes exceeded the middle threshold of the VPN instance multiplied by the maximum number allowed.

Cause 2: The middle threshold for the number of routes allowed in the VPN instance was reduced.

Procedure

1. Run the display ip routing-table limit command to check the configured middle threshold and the current total number of routes.

2. Run the display ip routing-table statistics command to check whether redundant VPN routes exist in the VPN instance.

If so, go to Step 3.
If not, go to Step 4.

3. Delete the redundant VPN routes and then check whether the alarm persists.

If so, go to Step 4.
If not, go to Step 6.

4. Run the display this command in the VPN instance view to check the routing-table limit configuration. Check whether the number of routes in the VPN instance reaches the middle threshold.

If so, the alarm is informational only, and no action is required. To clear the alarm, run the routing-table limit number { alert-percent | simply-alert } command to reconfigure a proper middle threshold. Then go to Step 6.
If not, go to Step 5.

5. Collect alarm information and configuration information, and then contact technical support personnel.

6. End.
