Simple recursive routing won't work over PPPoE, what I miss?

Hello,

I face really silly situation that should be resolved in seconds but it won’t. I try to do simple recoursive routing like this:

I got RB951 (tried different ROS versions from 6.26 to last RC of 6.30) with one PPPoE WAN link. I set up PPPoE client, it run and up, but I set not to receive default route from PPPoE server.

Now I set up two routes:

1) route 8.8.8.8/32 -> PPPoE-Client interface

2) route 0.0.0.0/0 -> 8.8.8.8

So traffic outside should go to the same way that 8.8.8.8 is visible - that is, via PPPoE-Client interface.

I did that many times (but these times it was over /30 p2p WAN links), and it worked every time, and this time I see no ping run outside and the second route is blue in the IP Routes table.

I tuned scope and target-scope parameters - without any good results.

So I decided to ask (after all, this is Friday and maybe I just too tired?) - how can bring my scheme to life?

Thanks in advance!
