Multicast problem

RouterOS Forwarding Protocols
1

Hi

I have hit a wall with the multicasting on mikrotik (routeros 4.11)

I have like this:

Source - subnet 1 (lan1 - interface) - ROUTER A - Wan ip provider 1<----->Wan ip provider 2 ROUTER B - subnet 2 (lan2)
192.168.250.0/24 10.124.175.0/24

In order to get from subnet 1 from router B to the subnet on router A i use a pptp vpn
pptp vpn ip on router a 172.16.5.1 and on router B is 172.16.5.2

I have followed the tutorial on the wiki (http://wiki.mikrotik.com/wiki/Manual:Multicast_detailed_example) and it is not working, and i really need this to work

On routing pim rp add address= what address do i enter??? 192.168.250.1 or 172.16.5.1 ?

Can someone shed some light on this?

Cause at the moment i only get “Join desired (*,G)= true, Upstream neighbor for RP 192.168.250.1 for group 224.0.1.55 not found”

If anyone could give me a working example would be swell.

Thank you

Nvm i figured it out. I will try and post a how to with cisco and with multiple MT for those interested.

as far as i have used multicast in my tests - it does not matter what ip address you set, just make sure that it is reachable through the multicast cloud using MRIB.
Then, if you receive stream through cisco, that usually does PIM-DM, you can point routers rp to cisco, because MT pim will not send PIM-DM request to stop mutlicast treams and ciscos neibor MT will receive the streams all the time, so joining that will actually start stream forwarding.

multicast is somehow sensitive to changes, so to make sure your changes has been applied you have to restart the router when you have done the changes to configuration, other way you can get weird messages, like one you just described.

edit: that is, if you try to just distribute some multicast streams and do not plan to broadcast yourself. else, you have to look into cisco as i saw, there could be some pim-sm configuration.
