Hi, Our IPv6 deployment overlays IPv6 on our IPv4 VLANs, so users/devices are in the same functional VLANs, but they have v4 and v6 access. The paths out are different for v4 and v6, we just inject /64's into the v4 VLANs from a parallel v6 hierarchy. Works fine. Yes, there is multicast in IPv6 where broadcast was an issue in v4. You also will want to prevent multicast flooding from multicast apps, so tighter submetting is nice (you get plenty of them in an IPv6 /48 :) Tim On Thu, Feb 20, 2003 at 04:43:17PM +0100, BEGIN, Thomas wrote:
Hello to all, I am wondering on IPv6 impacts over a company network's architecture. I mean, a big IPv4 network has to be divided in several VLANs in order to lighten the available bandwidth (sometimes for security reasons but it is not my interest in this case). And this because broadcast messages are received and examined by all network adapter. Thus comes my question: As there is no more broadcast messages but only multicast messages in IPv6, is there still a need to divide a big network in smaller networks (VLANs) ?
Thanks
