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 does not send IPv4 ICMP redirect messages.
