So on the firsgt page of the PIM Stub URL, in the first paragraph on the whole page it says "Multicast control plane traffic is always seen by every router on a LAN environment. The Stub IP Multicast is used to reduce and minimize the unnecessary multicast traffic that is seen on LAN in the access layer and save the bandwidth on the media to forward multicast traffic to the upstream distribution/core layer.
In the Catalyst 3750 and 3560 Series Switches, the PIM Stub Multicast feature supports multicast routing between the distribution layer and access layer. It supports two types of PIM interfaces: uplink PIM interfaces and PIM passive interfaces. In particular, a routed interface configured with the PIM Passive mode does not pass/forward PIM control plane traffic; it only passes/forwards IGMP traffic."
Check the feature navigator for the version of software you are running, if multicasting is available:-
I can read... That's not the problem... I do not understand what that means. Control plane traffic ? Multicast routing between access and distri layer ? That's why i opened this conversation.. I think tha't it is not possible with the ip base image..

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
For now I am planning on use Layer-2 s...
