why cbcp option is not in the pppoe request packet

why cbcp option is not in the pppoe request packet

[Mondayfox]

I tried to connet to win2003 RAS with linux redhat5,but failed.
After capturing packets , I found there was no cbcp option in the packet .
Then I made the cbcp=y in the pppd makefile ,and compiled again ,but still
failed. why?
do I need to compile pppoe again ? which files does pppoe need?

But the peer accepted the host's rejection of CBCP, so CBCP is not
required.  What makes you think CBCP is required?  Is the peer
configured to callback?

The debug log shows LCP termination request from the peer immediately
after the host sends an EAP response.

Are you sure you wish to authenticate to the peer using EAP?  Have you
tried "refuse-eap" option?

Not related to your problem, but you should fix this problem.
