5.3 Multicast Filtering
Just wanted to clarify the solution for this task. The task states to deny sending multicast traffic out F0/0 with a TTL value less than 13. My understanding is that a multicast packet will be forwarded if the packet's TTL is higher than or equal to the interface TTL. In this case, it should be set to
ip multicast ttl-threshold 13
The solution is set to 12 which will allow packets with a TTL of 12 to be forwared.
