Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

PrefixCount

Indicates the number of IPv6 route prefixes in the routing table.

MaxValue

Indicates the maximum number of IPv6 route prefixes supported by the device.

Impact on the System

New IPv6 route prefixes cannot be added to the routing table. Services will be affected if the number of IPv6 route prefixes keeps increasing.

Possible Causes

A large number of IPv6 dynamic protocol routes (BGP or IGP routes for example), static routes, or direct routes were added to the routing table.

Procedure

  1. Run the display ipv6 routing-table statistics and display ipv6 routing-table all-vpn-instance statistics commands to check the numbers of IPv6 public and private route prefixes and the number of routes of each protocol that are added to the routing table.

    Check whether services need these routes or whether the routes are added to the routing table due to incorrect configurations.
    • If the routes are added to the routing table due to incorrect configurations, go to 2.

    • If services need these routes, replace the license or contact technical support personnel for specification expansion.

  2. Adjust the configurations to delete unneeded routes, and check whether the RM_1.3.6.1.4.1.2011.5.25.145.11.2 hwIpv6PrefixExceedClear alarm is generated.

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