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 VPN IPv6 routes to be added to the routing table exceeded the middle threshold of the VPN instance.

Cause 2: The routing-table limit command was run, or the existing configuration of the command was modified to reduce the middle threshold.

Procedure

  1. Run the display ipv6 routing-table limit command to check the configured middle threshold and the current total number of routes.
  2. Run the display ipv6 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.
