VB OID	VB Name	VB Index
1.3.6.1.4.1.2011.5.25.145.8.1	hwCurIpv4PrefixNum	-

Impact on the System

If more IPv4 routes are added, they will be discarded.

As a result, traffic may be interrupted.

Possible Causes

The number of IPv4 prefixes exceeded the maximum value.

Procedure

1. Run the display ip routing-table statistics command to check the number of IPv4 public route prefixes and the display ip routing-table all-vpn-instance statistics command to check the number of IPv4 VPN route prefixes.

2. Check whether the number of route prefixes of each protocol is within the normal range.

If the number of route prefixes of each protocol is within the normal range, go to 4.
If the number of route prefixes of each protocol is not within the normal range, go to 3.

3. Delete unneeded IPv4 routes and then check whether the alarm persists.

If the alarm persists, go to 4.
If the alarm is cleared, go to 5.

4. Collect trap, log, and configuration information, and contact Huawei technical support personnel.

5. End.
