problem with PPPoA on 3640

dear,

I hsve a modem ADSL (alcatel) attached to an ALCATEL DSLAM ...the dslam is attacched to an LS1010 to port atm0/0/2 ... on the port atm0/0/3 is attached a router 3640.

id like to make a PPPoA connection beetween the modem alcatel and the 3640.

Is correct on the 3640 this conf for PPPoA..??

The modem alcatel has pvc 8/35 crossed on the dslam with pvc 0/32 that is crossed with the 3640 at pvc 1/33.

Thanx a lot

Re: problem with PPPoA on 3640

If the dsl CPE is configured with its own ip address to be negotiated (means 3640 will not allocate the ip address)during IPCP negotiation in PPP then the config looks ok to me. If the things dosen't work then we need to debug it first at PVC level and after at PPP level.Thanks..Tejal
