I've been playing with v6 on a VM slice and it's been working fine, but
of course that's not a real test.

I haven't run the newer versions of ROS on a PC yet. V5 was unstable

but it is AMD Phenom II and doesn't see traffic aside from DNS.
Rumor has it v6 is pretty nice on x86. I'd love to hear confirmation
from anyone. V5 enabled use of some Intel cards not working in v4,
however would randomly reboot due to a QoS bug with that particular
kernel.

Oh, and if you really want to have a lot of horsepower.... why not
go with a generic rackmount PC, with redundant power supplies and
fans?� Serious question to those with more MT experience than
I.... any problems with doing that?

I see all this discussion on CCR and not running BGP on it. I run
full tables with 2 external peers on my CCRs with no issue (1 has

software releases). I am not terminating PPPoE on the devices.
You guys are scaring me now. What would you recommend for an x86
product to handle about 800Mbps of traffic with at least 2
external BGP peers and full routes? I see all these products that
have atom processors, but that does not see large enough. I was
hoping I could find something with Xeon processors.

For the moment, anything with more than 1 full bgp feed really
should be a x86 product, in v7 that may change, but the limited
CPU for BGP in the CCRs is a major factor in our designs for our
customers.

I�m a bit confused.� What symptoms did you see with your

CCR caused his Edge router to bomb.� Replacing the CCR
didn�t fix the problem until they rebooted the Edge router.�
Did your routers cause other routers to degrade or crash?

I�m not sure about there being an issue with 6.19 on the CCR

recently.� I would suspect that he�s having an issue with
BGP on the CCR.� In our case, the CCR had 2 full BGP tables,
PPPOE and OSPF on it.� It took down one of the BGP peers on
the Edge router (PowerRouter V3 in our case).� I disabled the
BGP peer on the Edge for about 5 minutes and everything worked
happily.� When I started it back up, everything was fine until
it randomly happened again.� We then shut down the BGP link
between the PowerRouter and the CCR.� The CCR does not seem to
be able to handle more than one BGP table if it�s doing
anything else.� Another CCR seems to be happy as an edge
router with 2 full tables on it.� It�s not doing any other
function though and we are in process of ordering an x86
replacement.

No, our needs are much simpler but we saw similar issues on 5
routers from 750�s to 1100�s.� Went back to 6.15 and
haven�t had a problem in 3 weeks.

Rory, thanks for your reply. Is your setup fairly similar to
ours? PPPoE, Accounting, and BGP all done by the Mikrotik? How
many sessions do you have and what kind of throughput?

On the older routers, we went back to 6.15 and things have been
rock solid.� We saw similar problems with 6.19.

Have you tried taking down the BGP session on the Edge router
for a couple minutes and then restart it?

CCR-1036 running RouterOS 6.19
�
After some serious amounts of testing, we felt our CCR was ready
to take the plunge. The core router talks BGP to our two
Imagestream Edge routers and gets all 500k+ routes from each in
about three minutes. Its PPPoE server manages to authenticate
the bulk of nearly 1800 customers in four minutes. All�s fine
and dandy for about 12 hours, then not so fine and dandy things
start happening. Overall traffic that should be near 600mbps
seems to top off around 400mbps. Edge 1 goes unresponsive, VRRP
doesn�t kick in on Edge 2 and the entire network degrades. All
devices on our public switch go partially unresponsive to pings
including our DNS servers, other various VM�s, and ESXi hosts
themselves.
�
Here�s the fun part: We took the CCR out, just flat out
unplugged it and turned on our old Core routers. They start
authenticating customers but they�re insanely slow in doing
it. It�s not until we reboot our Edge 1 router that things get
back to normal and the old Core routers authenticate at
acceptable speeds. Could the CCR be inducing a problem in our
Edge routers perhaps?
