Re: LCP always down on PPPOE configuration

Hello,

 

Could you please give output for below command ? . There could be a chance that ISP dont respond back for the conf-ack that we sent for the conf-request that srx received.

Couple of things!

 

1- are you sure your connection type is PAP ?

2- try to disable RFC2486.

 

Also try to run

run show ppp stastics detail

 

and paste here.
