Afternoon all! I'm trying to work through some issues that I've been experiencing with multicast, and I suppose it's sparked my curiosity. The setup I have is about 5 RPs. The 5th one being 225.0.0.0/8, and effectively covers the other ranges. One ro...

Hi, Just curious if anyone has found a tool/utility in ACI that can be used to check if ports are open on remote devices. Such as telnetting on a port? This was always a useful tool to me on non-ACI equipment so it would be a shame if Cisco deprecia...

Hi Richmond, Thanks for getting back. Everything in terms of ACI was correct. EPG, BD etc. My particular set up involved the insertion of a another device between the IPNs. It was this device which was missing the multicast configuration. Managed to ...
