I am trying to get PPPoE DSL setup on a 2811 with SBC Global Internet and I am having some issues. I followed a configuration that was posted and everything worked and came up with full L3 connectivity to the internet until I did a reload on the router.
Upon Reload I get the following message about every second:
000066: *Jun 6 16:02:05.791 CDT: %DIALER-6-BIND: Interface Vi1 bound to profile Di1
000067: *Jun 6 16:02:05.795 CDT: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up
000068: *Jun 6 16:02:09.679 CDT: %DIALER-6-UNBIND: Interface Vi1 unbound from profile Di1
000069: *Jun 6 16:02:09.683 CDT: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to down
I must be missing something very simple, and ATT/SBC reps are trying to play the 'we dont support that router' game. Any help much appreciated, and points awarded.

=) Thanks! That actually solved my issue ... when I saw the debug ppp authentication and the string was xxx2sbcglobal.net instead of xx@sbcglobal.net I was able to solve the problem right away. Points!

Good. Also note:
vpdn enable
!
vpdn-group ppoe
request-dialin
protocol l2tp ! The guide I had put "pppoe" here which was not an option. I tried both l2tp & l2
None of the above is needed, whatever the guide says.
interface ATM0/0/0
bundle-enable
That doesn't do anything
dsl operating-mode auto
that is better set to itu
hold-queue 224 in
Really no need to increase input queue
interface Dialer1
dialer-group 1
PPPoE doesn't need dialer-group. Connection is always open.
router eigrp 10
passive-interface ATM0/0/0
That interface is not IP-enable, no need to make it passive.
ip route 0.0.0.0 0.0.0.0 x.x.x.206 !ISP Router
Alternative to that, use "ppp ipcp default router" under dialer
Thanks for the appreciation and good luck!

Thanks again!
I took all of your suggestions except for dsl operating-mode and default route since I have a static block to work with.
I am sure that I will come up with a few more questions, but it is great to have so many professionals that are willing to help out! I'll make sure to scan the forms a bit to return the favor.

No worries, in networking (almost) everything has an explanation.
"dsl operating-mode" doesn't have perceptible differences except the router never attempts the legacy ANSI ADSL modulation that is not used anymore.
"ppp ipcp default route" installs the default route via PPPoE once established, no difference if you have a block or not. Really a matter of "being clean" more than anything else.
On the matter of having a static block, most likely you will use the additional addresses to route them (with NAT or without) to inside devices. Certainly you don't want them be routed back toward the PPP link, like your configuration does currently.
