ALM-303046921 The number of public IPv4 prefixes exceeded the maximum value

Description

RM/2/PUBLIC_IPV4_PREFIX_EXCEED:OID [OID] The number of public IPv4 prefixes exceeded the maximum value. (PrefixCount=[Integer], MaxValue=[Integer])

The number of IPv4 public route prefixes exceeded that supported by the system.

Attribute

Parameters

Impact on the System

New IPv4 public route prefixes cannot be added to the routing table. Services will be affected if the number of IPv4 route prefixes keeps increasing.

Possible Causes

Cause 1:

A large number of IPv4 dynamic protocol routes (BGP or IGP routes for example), static routes, direct routes, or UNR routes were added to the routing table.

Cause 2:

The maximum number of IPv4 public route prefixes supported by the system was decreased.

Procedure

1. Run the display ip routing-table statistics command to check the number of IPv4 public 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_1.3.6.1.4.1.2011.5.25.145.19.1.2 hwPublicIpv4PrefixExceedClear alarm is generated.
   • If the RM_1.3.6.1.4.1.2011.5.25.145.19.1.2 hwPublicIpv4PrefixExceedClear alarm is not generated, go to 3.
   • If the RM_1.3.6.1.4.1.2011.5.25.145.19.1.2 hwPublicIpv4PrefixExceedClear alarm is generated, go to 4.

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