PPPoE server problems

Thu Feb 21, 2013 6:14 pm

Hi.
I have a serious problem with ROS. I have a Cisco 7200 that I want to (partially) replace with a RB1100AHx2. The C7200 terminates some hundereds of PPPoE connections.
The problem is that if I try to connect an Asus RT-N10E, it can't. I have the problem also with other kind of routers (for example with some old Netgear).
I have tried also with a RB951G-2HnD, with 5.22 and 6.0rc9, with same results.
With C7200 I have no problems!

This is RB log:

Looks like the RADIUS response is not sending the correct authorization parameters to enable LCP to establish in the build stage of PPP.

Check your RADIUS config. I run Cisco 7201's and ASR's for PPPoE BRAS and also MikroTik, the two profiles for each are extremely different.

Would need to see what attributes you are passing in the response...
