I have high cpu on a netscreen isg-2000. Juniper is saying it could be due to ipspoofing that is on the mgmt interface. Im not sure as the ipspoofing events have been happening for a while now.. but lately the CPU is very high. I guess my question is, how do I troubleshoot the ipv6 spoofing?

get event example:
IP spoofing! From 8006:6c8e:a82:283f:
a82:28f7:50:ab77 to ff02::1, proto 58
(zone MGT, int mgt). Occurred 1 times.
There is a lot of these events.
Any information would be great.
Thanks
