I am trying to configure a network that is capable of spoke-to-spoke multicast traffic. The end result will be effectively a multicast bridge for multiple seperate networks.
I have read over the "Multicast over IPsec VPN Design Guide" as well as the relevant sections in the "IPsec VPN Design" book and "The Complete Cisco VPN Configuration Guide" book and I am still at a loss.
I am using a Cisco 1841 router as the VPN hub and two (soon to be more) Cisco 1811 router as the VPN spokes.
Currently I am trying to use DMVPN to configure and IPsec VPN system, but if I am reading the "Multicast over IPsec VPN Design Guide" correctly, spoke-to-spoke multicast traffic is not possible. I am refering to the third paragraph in the overview section on page 29 of that PDF.
I have been able to connect both of the spokes to the hub and send unicast traffic from each spoke to the other and to the hub. I have also been able to send IP multicast traffic from the hub (server) to the spokes (clients). However when I configure the system so that spoke A (server) is sending the IP multicast traffic, the hub receives the traffic correctly, but the spoke B only receives the very first multicast packet of the stream from spoke A.
My main question is this, can an IPsec (or other) VPN support spoke-to-spoke mutlicast traffic. And if so, how will I need to configure it.
Any information that you can provide related to this will be very appreciated.
