I have been trying to configure BGP and PIM-SM on my hEX router using winBOX. But I haven’t been able to. BGP seems to be working, I can see around 2000 BGP learnt routes in IP→Routes. But the end goal is to receive multicast UDP data through PIM-SM which I haven’t been able to. IGMP join packets are going from the CPE_TAP_IP to 224.0.0.22, but thats about it as far as I can see. Can someone help me out here?

We need this setup urgently.

Thanks

Edit:
I am trying to mimic the cisco configuration.
My current config:

BGP is working, PIM-SM is showing neighbor, but I can’t see multicast UDP packets.

Hi,

What is the Mikrotik configuration?
The CISCO configuration is the one you want to mimic or is it a source where you connect to?

More details give more answers.

Hi @BartoszP , thanks for the response.
I am trying to mimic the cisco config. I can send my current mikrotik configuration, but how do I do it in a concise manner? (Interfaces, BGP, PIM-SM, Firewall, etc)

/export file=anynameyouwant

and emove any credentials or other secrtets

When you post code surround it with code tag < / > that puts 3 backticks + RouterOS language definition
