I have a pair of RVS 4000 routers bridging two sites with a VPN and all is fine, save for the fact that most of the resources I need to access through the VPN rely on multicast packets to advertise their availability. Is there any way to tell the routers to route multicast packets across a VPN? As far as I can tell there is not, but I thought I better ask.
If there is no way to route multicast packets over the VPN then my second question is how does one go about getting Cisco to add a feature? Mutlicast is increasingly important to the Small Business market being targeted by these products. NAS devices, printers, scanners and all sort of other devices are using UPnP, mDNS and other multicast protocols to make themselves findable when they are getting their IP addresses using DHCP. Half of Apple's product lines rely on Bonjour, which is mDNS under the hood. The point of a VPN is to allow offices to join together, supposedly seamlessly, but without multicast routing most of my resources are inaccessible half the time.
