[HECnet] Cisco Tunnel Project

If you are interested in getting auto-generated tunnel configs please send me the following information: 1) The email address you want new configs sent to 2) Your routers public IP address(es) 3) The source interface(s) for your tunnels in full interface text. re: FastEthernet0/1 4) The cost you want your tunnels to be if you don't want them to be 10. Once you've gotten your first config text from me delete all your current HECnet tunnels and then apply the config text you'll have been emailed. Unless anyone objects, I'm starting tunnel indexes at 50. Steve D. -- if you want a router let me know. I'm going to eventually get off my ass and migrate to this 2851 which will free up the 1841. I'm more than happy to loan it to you as long as I have no need for it. (Which I doubt I ever will) The one question I have for everyone is.... Do we do a full mesh or do we choose 1-3 "hubs" to connect everyone to? If 20 people have cisco's and we do a mesh that's 20 tunnels, FYI. I'm ok with that, but I want to get an idea of what everyone else thinks. -brian . Do you have any idea if the mesh would create lots of traffic? I mean that if there are 20 Area Routers exchanging hellos all the time and route updates every now and then, how much bandwidth would that need? I think many participants have e.g. an ADSL connection with 1Mbit/s or something like it. Would the continuous routing traffic cut a significant slice of the bandwidth? Anyway, the mesh idea sounds good. I vote for it. I think it has benefits like better availability in case of power outages or HW failures and better distributed traffic between the various areas.
