Hello everyone,
I've had to deal with a rather serious problem:
on a CCR1072 / RoS 7.14.1 router - BGP absorbing 2*full-table IPv4 + 2*full-table IPv6 for approximately 2Gbps of incoming traffic;
I wanted to try to trace a connection and thus to try a "tool/sniffer/quick..." by filtering only on the IP
after a few seconds of sniffing, the router rebooted itself via the watchdog.
Imagining that I'd been a bit too adventurous to run this command on this router, I then ran it again on its neighbour - which handles the same amount of traffic, but this time doesn't handle full-tables, and "only" has around 1000 to 1500 routes.
This neighbour is also a CCR1072 but in RoS 6.49.13.
The same command started to work, again for a few seconds, then rebooted by the watchdog...
So I have a simple question:
Is the amount of 2Gbps traffic really too much for this type of command to be executed?
I would have imagined that a CCR1072 could handle all that more easily...
Or am I focusing on the wrong problem, and probably missing something on the side?
The consequence of these crashes has been to make a big mess of our entire backbone for a few minutes, so I'm not going to be able to repeat the experience easily for testing purposes...
Re: sniffing is crashing ?
Sniffer crashes here too.
Here's my model info
It's the first crash I've had since getting the Routerboard about 10 years ago.
Here's the sniffer configuration.
