I have a router with a PPPoE dialer that disconnected and i don't know why. This Dialer has been working for months without problems until last wednesday when the problem started.
I have control of both routers, CO and CPE.
Into CPE the state of PPPoE is this, (i have two ADSLs, the wrong one is on ATM0/1/0)
CPE#sh pppoe session
2 client sessions
Uniq ID PPPoE RemMAC Port Source VA State
SID LocMAC VA-st
N/A 32026 0016.46e7.f160 ATM0/0/0 Di2 Vi3 UP
0024.c490.e623 VC: 8/32 UP
N/A 46460 000a.f343.741c ATM0/1/0 Di1 N/A PADISNT
0024.c490.e626 VC: 8/32
If i set a debug #debug pppoe packets interface ATM0/1/0 i don't see anything.
But, when I clear PPPoE session (cle pppoe interface ATM0/1/0) into CPE I see this several times and nothing more.
.Apr 8 10:34:45 METDST: pppoe_send_padi:
00 06 09 00 AA AA 03 00 80 C2 00 07 00 00 FF FF
FF FF FF FF 00 24 C4 90 E6 26 88 63 11 09 00 00 ...
Into CO I don't see the packet PADI.
If I ping atm from CO to CPE it works.
CO#ping atm interface atm1/0.1 1 45005
Type escape sequence to abort.
Sending 5, 53-byte end-to-end OAM echoes, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/32/36 ms
Then I think that ATM layer is OK.
And I can restore session when I delete pvc and reconfigure again.
CPE(config)#interface ATM0/1/0
CPE(config-if)#no pvc 8/32
CPE(config-if)# pvc 8/32
CPE(config-if-atm-vc)# encapsulation aal5snap
CPE(config-if-atm-vc)# pppoe-client dial-pool-number 1
Now I see this in the CPE debug

CO is a Cisco 7200 with an ATM port adapter
This is part of his config,

and in the other side i have a Cisco 2811 with a HWIC-1ADSL-M and this is the config.

I tried to change HWIC but the problem persist.
Any idea?
Thanks in advance.
