The TTL for multicast packets is 0. The default value 0 means that all multicast packets are forwarded out to the interface.

            ttl-threshold ttl 
        }
    }
}

Use the set form of this command to configure the multicast TTL value.

Use the delete form of this command to restore the default TTL value for multicast.

Use the show form of this command to show multicast TTL configuration.
