topic Spoke-to-spoke multicast problems in Network Security https://community.cisco.com/t5/network-security/spoke-to-spoke-multicast-problems/m-p/1060734#M963569 <P>I have am trying to setup a network for a video surveillance system. The network is setup in a hub spoke configuration with multicast sources and receivers at all of the spokes. I am using a DMVPN configuration to encrypt tunnels from the spokes to the hubs and spokes to spokes. I am currently able to to get multicast traffic to the hub from all of the spokes but I can't see to get it from spoke-to-spoke. I don't know that much about configuring multicast so it may be a simple mistake on my part. I have attached configs from two of my spoke routers and my hub router. Thanks in advance for any help or suggestions. </P> Fri, 21 Feb 2020 11:04:05 GMT kymera-it 2020-02-21T11:04:05Z Spoke-to-spoke multicast problems https://community.cisco.com/t5/network-security/spoke-to-spoke-multicast-problems/m-p/1060734#M963569 <P>I have am trying to setup a network for a video surveillance system.

I can get unicast traffic between the spokes but not multicast. Multicast is not an area I know much about. I have tried several things that I have found online but am not sure how get the multicast from spoke to spoke. I am not even sure if I am setting multicast correctly on the routers. Most of the examples I have found are only for one source and several receivers and I have many of both.</P></BODY></HTML> Tue, 28 Oct 2008 21:06:44 GMT https://community.cisco.com/t5/network-security/spoke-to-spoke-multicast-problems/m-p/1060738#M963573 kymera-it 2008-10-28T21:06:44Z Re: Spoke-to-spoke multicast problems https://community.cisco.com/t5/network-security/spoke-to-spoke-multicast-problems/m-p/1060739#M963574 <HTML><HEAD></HEAD><BODY><P>Perhaps a better design would be to integrate DMVPN with IOS Secure Multicast.
