Fix Recommendation

Configure the SUSE operating system to not accept IPv6 source-routed packets by adding the following line to "/etc/sysctl.conf" (or modify the line to have the required value):

net.ipv6.conf.all.accept_source_route = 0

Run the following command to apply this value:

# sysctl --system

Check Contents

Verify the SUSE operating system does not accept IPv6 source-routed packets.

Check the value of the accept source route variable with the following command:

net.ipv6.conf.all.accept_source_route = 0

If the returned line does not have a value of "0", this is a finding.
