I run all of mine that are mission critical in a dual set up so that at
any time they will automatically or can manually be switched to the
secondary. I do this not only with Mikrotik, but any platform that
doesn't have redundant controllers/switch fabric.
Richard,
I have recently reviewed both Juniper and Nokia BNG "Broadband
Network Gateway" router platforms. They are rather expensive to get in
to but for massive CGNAT and subscriber management I don't think
anything else comes close. The Nokia of course is the priciest, but it
is ridiculous what they can do I've been working on them for years for
metro Ethernet, but just recently tried out the BNG feature set and
hands down the best. The Juniper is much easier to get in to as well as
possible in a smaller form factor.

Yup.. we have several 1072s passing 10+GB that reboot randomly.. we’ve
had to distribute traffic across several to keep the load down to 7-8,
and then they don’t..
Replaced them, upgraded, went through the MT support same
recommendations.. no answers.. I have 2 extras sitting on my shelf for
when they tank.. just a matter of time.
Also whatever you do, don’t torch a 10gb connection.. every time we’ve
tried, they’ve locked hard..
At this point, we are reviewing options on higher end / different
hardware for the CG-NAT side of things.

*Subject:* [AFMUG] Mikrotik 1072 Frustrations
MIkrotik has been rock solid for me for years. Until this year and
the 1072's. Random reboots set off by watchdog timer on all of my
1072's. Some more than others. Threads in the forum all discuss the
same problem exactly. Its a connection tracking issue.. however I
need connection tracking on one particular router. I've adjusted
everything I could. Firmware and board firmware all up to date etc.
Happens randomly with low levels of traffic, high levels of traffic,
sometimes a couple times a day, sometimes weeks. No DDOS evidence at
all from upstream routers. Configs checked and rechecked by third
party experts. I graph everything about the Mikrotik and there are no
clues or anything abnormal happening before the crash. Plenty of
memory, disk space, CPU etc. Replaces all the trannies, power
cables and such. Not running BGP only OSPF on the one that is giving
me the most trouble.
Even have a serial console cable plugged into them to my opengear and
set it to log pretty much everything to console including the kernel
and nothing. A hard freeze.
Then there is Mikrotik support... I've never needed their support
before until now. So I put a ticket in and the shitty attitude I'm
getting from them seems like they KNOW there is something wrong with
the hardware and they are intentionally not being helpful. It is
pretty clear to see with all the people reporting this issue that
there IS an issue.
If this is any indication of how things are going to go with Mikrotik
on the newer hardware going forware I think its time to jump to an
enterprise level system. Juniper most likely. Shame because they are
just about keeping up with the demands with their hardware. Getting
closer to 100Gbps etc and ROS7 ... but at their current pace I think
we've outgrew them.
All the threads discussing this issue has been absolutely quiet when
it comes to Mikrotik jumping in to mention or try to help
troubleshoot. I think they know they had bad hardware out there and
do not want to honor warranties. I've heard rumors of bad batches of
1072's.
Anyone else encounter this?
