Enable Multicast

We now explain how to enable Multicast within the mini-Internet.

Turn on PIM on the FRR routers

You must replace pimd=no with pimd=yes in the daemons configuration file to turn on the PIM protocol for the FRR routers.

Use a host image that provides Multicast tools

The docker containers used for the hosts within the mini-Internet must come with basic Multicast tools that are required to test it. The hostm docker image includes multicast tools such as smcroute or mtools and can be used instead of the host image. The vlc docker image comes with vlc, which is useful to stream a multicast video. Feel free to use your own image if you prefer.
