Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

VpnInstanceName

Name of a VPN instance

PrefixCount

Current number of IPv6 route prefixes in the VPN instance

Threshold

Alarm threshold for the number of IPv6 route prefixes in the VPN instance

Impact on the System

The number of IPv6 route prefixes in the VPN instance is approaching the maximum number that is allowed, and route prefixes will no longer be accepted if the maximum number is reached, affecting services.

Possible Causes

Cause 1:

A large number of IPv6 VPN dynamic protocol (BGP or an IGP), static, direct, and UNR routes were added to the routing table.

Cause 2:

The alarm threshold for the number of IPv6 route prefixes in the VPN instance was reduced.

Procedure

  1. Run the display ipv6 routing-table vpn-instance vpn-instance-name statistics command to check the total number of route prefixes and the number of route prefixes of each protocol. Then run the display ipv6 routing-table limit command to check whether the number of IPv6 route prefixes in the VPN instance has exceeded the alarm threshold.

    • If the number of IPv6 route prefixes in the VPN instance has exceeded the alarm threshold, go to Step 2.

    • If the number of IPv6 route prefixes in the VPN instance has not exceeded the alarm threshold, go to Step 3.

  2. If the configured private network prefix threshold value is too small, run the prefix limit command in the IPv6 address family view of the VPN instance to reconfigure the threshold. Then check whether the fault is rectified.

    • If yes, go to step 4.

    • If no, go to step 3.

  3. Collect alarm information and configuration information, and then contact technical support personnel.
  4. End.
