I haven't run the newer versions of ROS on a PC yet. V5 was unstable on x86, at least on a Core i7. Seems stable enough on our DNS server, 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. ----- Original Message ----- From: Bruce Robertson via Af To: [email protected] Sent: Thursday, September 25, 2014 6:40 PM Subject: Re: [AFMUG] CCR-1036 fun with PPPoE 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 run full tables with 2 external peers on my CCRs with no issue (1 has been up for 240 days and the other 367 days running 6.2 and 6.4 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.

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? � � Chris Wright Velociter Wireless � -------------------------------------------------------------------------- Total Control Panel Login To: [email protected] From: 00000148a9cf7626-53a62885-89e0-4e1c-9c7f-b4d8519c55eb-000...@amazonses.com Message Score: 2 High (60): Pass My Spam Blocking Level: High Medium (75): Pass Low (90): Pass Block this sender / Block this sender enterprise-wide Block amazonses.com / Block amazonses.com enterprise-wide This message was delivered because the content filter score did not exceed your filter level. � -------------------------------------------------------------------------- Total Control Panel Login To: [email protected] From: 00000148adacf3bf-5f506628-914e-4ce6-9d2a-4598e0293a55-000...@amazonses.com Message Score: 2 High (60): Pass My Spam Blocking Level: High Medium (75): Pass Low (90): Pass Block this sender / Block this sender enterprise-wide Block amazonses.com / Block amazonses.com enterprise-wide This message was delivered because the content filter score did not exceed your filter level. � !DSPAM:2,5424a4d166972502612029!
