when we started to test the CER 2024F-4x in our environment we discovered high cpu load as well, when using IPv6.

"sh cpu lp" was at unusual high levels:

09:15:15 GMT+01 Thu Sep 26 2013

SLOT #: LP CPU UTILIZATION in %:
in 1 second: in 5 seconds: in 60 seconds: in 300 seconds:
1: 67 67 67 67
2: 67 67 67 67

The root cause was found in a high amount of ipv6 discovery and solliciatations.

In our specific case it was fixed in 5500d, and the issue was traced back to the fix made for 459558 in 5500c.


Best regards
