I am having problems with a Bellsouth DSL config under 12.3(11)T3, I
believe it may be an IOS issue. When I reload the router it connects,
I get my IP, but then it shortly disconnects, and it will not
reconnect. I flap both the e0 and dialer1 interfaces, but nothing. No
matter what I try to clear using "clear pppoe", this always remains:
nco#show pppoe session
1 client session
Uniq ID PPPoE RemMAC Port VT VA
State
SID LocMAC VA-st
N/A 4007 0003.4272.c002 Et0 Di1 Vi1
N/A
0004.dc0c.ead9 DOWN
Yet Dialer1 no longer shows an IP address set:
nco#show ip int dialer1
Dialer1 is up, line protocol is up
Internet address will be negotiated using IPCP
Broadcast address is 255.255.255.255
MTU is 1492 bytes
Helper address is not set
Directed broadcast forwarding is disabled
Outgoing access list is not set
Inbound access list is not set
debug ppp auth and neg just repeatedly shows:

Its strange that I can reload the router, and it will come up, but once
the connection has dropped, I have not been successful in revising it.
Anyone have luck with 12.3(11)T3 and DSL/PPPoE? See anything in the
config below that may be questionable?
