I think you might be seeing something from the debian end coming back. RouterOS to RouterOS will fragment for you (and I can do heaps of mbps either fragmented or not) with no issues. I wonder if the Debian box is sending a large frame that is killing the RouterOS?

Hey Thomas,
Nothing out of the ordinary being logged on the debian router. It all seems to be based around the first /24 from the /22 - I can advertise the other three /24's no problems.
Given that it's looking like a tunnel MTU issue, my next step is going to be to un-advertise everything, and see if simple pings (with large MTU) will crash the RouterOS VM.

Is the Debian router at the other end logging anything weird on its end?
What happens if you advertise as 4x /24's instead of the single /22?
Any chance of getting a packet logger somewhere in the chain so you can see exactly what the two routers are saying to each other?

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
