But this quickly reduces to hierarchical routing: consider 3 communities, C1, C2, C3. Connectivity is C1 == C2 == C3 (i.e. no direct connectivity between C1 and C3). The connecting member between C1 and C2 needs to know everybody in C1 and C2 - that's clear. But it also needs to know endpoints

Hi. I think it should be more complicated than this. The suggested solution has a dichotomy of either a full mesh or a start topology. The requirements should cover scenarios such as a mesh within an organization connecting to a hub to gateways outside the organization, or multiple hubs

Hi Yaov, If I udnerstand correctly, what you seem to be talking about is a Star-of-meshes or a mesh-of-star topology. In my view this would be dealt with in 2 different iterations of the Mesh VPN topology. So there would be a Mesh VPN for the Star topology and a separate instance of the Mesh VPN

I might have put it like this if it wan't so similar to the way things are configured on Check Point gateways :-) It makes sense to me, but I'm not sure it covers all the use cases. Imagine a topology that is entirely mesh, except for HTTP(S) traffic that is routed to a central site because

Hi, I would like to start off by trying to resolve the issue. The notes from the IETF are attached below. Description:Some admins prefer a star topology so they can inspect traffic. They may not want to use this technology. Detail arguments: My take is similar to what Yaron and Yaov seem to
