Multicasting between VLANs
I'm currently configuring up our 3COM 5500G-EI Layer 3 Switch for VLANing across the school.
All the appropriate VLANs, VLAN Interfaces etc, DHCP Helper, trunk ports etc have been setup, and all the computers are connecting; allocated a correct IP address and can successfully access devices inbetween VLANs.
I just need some advice on what settings I would need to configure on the switch (all the other switches are 3COM as well) to allow multicasting across VLANs? (for Ghost, Windows Deployment).
I've come across various potential commands:
rip version 2 multicast
On Edugeek, i've only found 1 post from last year that suggested dense mode, but this initially floods the network to find members of the multicast, whereas sparse mode doesnot.
Again, any assistance (as the 3COM, H3C, HP support forums are not very helpful on this topic!) would be very much appreciated.
