Thanks, that didn't make a difference either. It occurred to me that the subnet I'm having trouble with is the only one I was advertising which is in decent use - the others only have one or two IP's in use each at present.. So I started thinking maybe it's a bandwidth or packet flow issue. Interestingly, I pushed the remote end MTU from 1452 to 1400.. And the router has now been online for 15 minutes without dying..?! Now the question is... Why is this end router dying when the remote end sends a large packet (or a packet goes missing?) IS the RouterOS ip4ipv6 tunnel implementation slightly buggy with lost packets? Maybe a memory leak overflow? On 27 March 2015 at 13:48, Tim Warnock <timoid@timoid.org> wrote:

Yeah, iBGP Remote router is debian with quagga purely passing on the advertisements it receives (with the appropriate filters incase I fubar something at this end ;) ).
Disabling the accept input filter didn't help. Disabling the output filter did help, but I already knew that - sending another prefix works fine also.. turning off multihop didn't fix it either :(
Thanks,
Damien

Ill try disabling the in filter - it doesn't crash if i disable the accept out filter - it also doesn't crash if I'm sending a different prefix out.

Does your VM crash then?

There's no autosupout.rif being generated :(
Sorry for the delay, I've been trying to work out what on earth is going on.
I've now started with a fresh (and 24hr licensed) 6.27 install, and absolute minimum config, and it's still shutting down. I've changed IP addresses locally, incase somehow the /28 from the /22 in question was conflicting.
Config is here: http://pastebin.com/pTDS5JPM
Within a minute or so of the bgp session coming up, the VM just shuts down. It's rather driving me nuts!
Any thoughts?
Thanks,
Damien
