In IPv6 strict compliance mode all IPv6 operations needs to be stopped when duplicate IPv6 addresses are detected. Because of this, BIG-IP may continue to send out configured route advertisements.
BIG-IP may continue using configured IPv6 addresses and send out RA even if DAD is detected.
This is applicable only to IPv6 strict compliance. Without it BIG-IP does not perform duplicate address detection (DAD) and always configures addresses.
Avoid duplicate address situations. With properly configured networks, this is no issue.
Duplicate address detection now behaves according to IPv6 RFC.
