RE: RFC1483 Bridging

Hi Jose,

I re-did this lab testing with 1841 running 12.4(11)T7 Advance IPSERVCES
image.

Router Model : 1841

Topology : 1841----MODEM(RFC1483
Bridge)---------DSLAM(LAC)----IPCLOUD----Providermanaged LNS

I enabled following debug

1) PPP Neg and PPP AUTH

2) Dialer events

When I tried to genarate the traffic I could see dialer is not initiating the
PPP at all.

Any ideas what could be wrong. I appreciate any help in resolving this issue.

ERIKS-TEST-R1#ping 172.20.83.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.20.83.1, timeout is 2 seconds:

Di1 DDR: ip (s=172.30.128.9, d=172.20.83.1), 100 bytes, outgoing interesting

Success rate is 0 percent (0/5)
