CRS317 routing speed with pppoe and L3 offloading

[Ianor]

Hallo Forumfolks,

I’m evaluating new hardware for routing and switching. I have a 1Gbps FTTH connection with pppoe authentication.

The CRS317 seems to fit perfect to my needs. Im just unsure how well it is with routing. The productsite says it can route around 1.2Gbps with ethernet only. How is the speed with pppoe? Should i go for a CCR? My ISP is using CCR1009-7G-1C-1S+ for his business customers.

Has anyone already done some throughputtest with L3 offloading with RouterOs 7 beta? How big is the benefit?

Thanks a lot for your answers.

Kind regards

Ianor

L3 offload will not work with pppoe.

It’s insane with ISPs that use PPPoE in such speeds. Customers will spend most of their CPU resources to encap/decap packets. It’s just sad.

Not sure that a CCR1009 will do it either. Maybe the RB4011 or new CCR2004 have the horsepower.

BTW CRS317 CPU has enough power to handle 1Gbps PPPOE traffic, probably on the edge but should handle it.

Can you say AS3320 Deutsche Telekom… Had to ditch my trusty 2011, since routing with pppoe (WAN), NAT, and a few dusin FW rules, anything (DL) much more than 100-120 Mbps is not possible to reach.

Thanks for your info. Sadly, the ISP is on a wholesale PoP from Swisscom, not on his own equipement in the town where I life. This is why I have to use PPPoE. The ISP uses DHCP Authentication on his own PoPs… Swisscom is planning to upgrade to 10G FTTH nodes in the near future. Therefore im favouring the CCR2004.

Thanks for this information mrz. As stated above, I will go for the CCR2004 now for my WAN connection and the CRS317 (or 309 or even 305) for the LAN.

Kind regards

I’ve an 1000/500 fiber connection from one of those insane ISPs (AS3320 Deutsche Telekom), an CCR1009-7G-1C-1S+PC can handle that.
But PPPoE (WAN), NAT, some mangle and a batch of FW rules sure are putting some noticeable stress on all cpu cores (each core is loaded around 20-50%) while maxing out the connection.

If your are aiming at 10G in the future, your choice of an CCR2004 will sure be the better option.
