How to set up Mikrotik Multicast for the subsequent installation of Proxmox-Cluster?

Question

network hardware

There are five machines with proxmox that need to be clustered, only Mikrotik from the network equipment.
It is required to collect a multicast group on the router (Mikrotik / routerOS), and send traffic back as UDP from the same interface and from the same port to which the traffic comes.
Attempts to add nodes manually to the group ended with the fact that the group is assembled, but the neighbors in the group do not see each other.

Answer 1

It looks like there are no ready-made solutions (it doesn’t google quickly), so there is only one option - to read the documentation:

Answer 2

Yes, collect on Unicast and do not worry about the brain
