Hi Folks, Still waiting for my CCR to come back after dying, so have temporarily cloned one of my RouterOS VM's and am running four of them to accomplish the same as the CCR (and once the CCR comes back the plan is to buy three other 'tik hardware routers, once I figure out exactly what I want/need, based on the resources these VM's are using) Anyway, I seem to be having a weird problem with one of the routers. it's a slightly strange config - I have ipipv6 tunnels between the router and a debian+quagga box in the US. Two tunnels on each of my upstream providers (one for v4, one for v6, as linux does NOT want to run dual-stack over the one tunnel). Since having issues, I've pulled it back to just the two tunnels between the two routers - one for V4, one for V6. I then run BGP over both of those tunnels, and use that to advertise my prefixes in the US. It works well - provided I *don't* advertise my primary /22. My two v6 /48's and my secondary /22 are advertising fine, and work well. However within 2-3 minutes of advertising my primary /22, the router reboots. And immediately reboots. And immediately reboots. And then shuts down. I'm not sure if it's routerOS doing the shutdown, or xenserver detecting the reboot loop and forcing it down. Has anyone seen that before? There's nothing obvious in the logs right before it reboots, and on boot it simply states that the previous shutdown was unexpected. It doesn't generate a supout, so I'm guessing it's not hitting a watchdog or anything? It has me wondering if this is the same reason my CCR1009 died? As I had exactly the same config on the CCR (except it was handling three full v4 + v6 feeds, AND running the three pairs of ipipv6 tunnels plus the three pairs of send-only feeds to the US) Has me rather pulling my hair out.. Wanted to get my 'new' config with everything separate labbed up and running in production before I go and lash out on all new 'tik hardware - but if 'tik isn't going to do one of them, then I lose the awesomeness of winbox, and may as well go back to cisco gear for all of it :-p Thanks, Damien -- Damien Gardner Jnr VK2TDG.
