I have a 460 with pim sparse to a external RP off my network. I pull 324 multicast via this sparse vlan. the rest of my network is currently dense, working as it is , I want to convert my entire network from dense to all sparse. which will cause me to have a different RP on my own network. could i use the inter-VR solution to pass multicast from my current sparse Vlan (add it to a new VR) over to the current VR-Default network soon to use sparse?
I was also considering using MSDP. thanks in advance,
