Impact on the System

If more IPv6 routes are added, they will be discarded. As a result, traffic may be interrupted.

Possible Causes

Cause1: A large number of IPv6 routes were added to the routing table.

Cause2: The maximum 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 IPv6 route prefixes in the VPN instance and the number of routes of each routing protocol that are added to the IPv6 routing table. Then, run the display ipv6 routing-table limit command to check whether the number of IPv6 route prefixes in the VPN instance exceeds the configured maximum number. - If the number of IPv6 route prefixes in the VPN instance exceeds the configured maximum number, go to 2. - If the number of IPv6 route prefixes in the VPN instance is less than the configured maximum number, go to 3. 2. Delete unneeded IPv6 VPN routes or run the prefix limit number { alert-percent | simply-alert } command to increase the maximum number. Then, check whether the alarm persists. - If the alarm persists, go to 3. - If the alarm is cleared, go to 4. 3. Collect alarm information and configuration information, and then contact technical support personnel. 4. End.
