Check Text (C-215430r991589_chk)

From the command prompt, run the following command: # /usr/sbin/no -o bcastping bcastping = 0 If the value returned is not "0", this is a finding.

Fix Text (F-16626r294742_fix)

Configure the system to not respond to IPv6 multicast ICMP ECHO_REQUESTs by running: # /usr/sbin/no -p -o bcastping=0
