I have a large network (500+) of remote sites on a non multicast public platform. I now have to support multicast traffic for my users and have thought that multipoint tunnels set up as an overlay on the current platform will do the trick.
At the moment I cannot get 2 remote sites to connect to the core site multipoint tunnel interface, although all tunnel sources and destinations are pingable....
Any help in the setting up of mGRE tunnels would be appreciated.
To deploy L3 VPN mGRE tunnels you will create a VRF instance, create the mGRE tunnel, redirect the VPN IP traffic to the tunnel, and set up the BGP VPNv4 exchange so that updates are filtered through a rout-map and interesting prefixes are resolved in the VRF table. The configuration steps are described in the following URL
I am trying to use mgre tunnels over an existing layer 3 network, to provide an overlay network for multicasting. I dont need to get into VRFs. I was just after using a mgre tunnel at the core end as it cuts down the configuration work and complexity.
