multicast and pptp

RouterOS General
1

I’m following the multicast routing guide found here. My question is, is it possible for the PIM interface and rendezvous point to be a PPTP connection?

Thanks

Yes, it should work on pptp and any other tunnel. I was running multicast over pptp in one of early 3.0 versions, if it is not broken then it should work.

Hmm I’m using v3.10. Do you see anything wrong with my config? I can ping between the PPTP tunnel and the neighbors show up in PIM.
