Configure the system to not send IPv6 ICMP redirect messages.
# ndd -set /dev/ip6 ip6_send_redirects 0

Also, add this command to a system startup script.

Check Contents

Determine the type of zone that you are currently securing.
# zonename

If the zone is not the global zone, determine if any interfaces are exclusive to the zone:
# dladm show-link

If the output indicates "insufficient privileges" then this requirement is not applicable.

If the zone is the global zone or the non-global zone has exclusive interfaces verify the system is configured to not send IPv6 ICMP redirect messages.
# ndd /dev/ip6 ip6_send_redirects

If the returned value is not 0, this is a finding.
