Hi Adam, Thanks for your response. My not working config was actually the same as yours but it still failed. After realising that it works for you I tried a different version of IOS and bang it worked. Ahhh! It's so hard to get an IOS version that is stable on GNS and doesn't have any bugs!
cheers, Ben.

The working config still gets the IP address via IPCP even though the command on the D1 interface is "ip address pool DPOOL". Both versions of the config negotiate the ip address for the client via IPCP. The only difference is the mask. Can you explain in a bit more detail where I've gone wrong (or at least point me in the right direction)? I'm aware that I have the client and server routers around the wrong way but I don't think that will stop OSPF from working. cheers, Ben.

While completing this section I found I couldn't bring up the OSPF adjacency because the PPPoE client had a /32 mask which made the address of the peer on a different network. I was able to get this to work by adjusting the mask using a DHCP pool with the origin ipcp command. While reading the DSG I was surprised to find that this issue was not encountered. The only thing I can see I've done differently is incorrectly making R2 the PPPoE server instead of the client but I don't think this would have anything to do with creating or fixing the issue. Can anyone explain why the DSG didn't have this issue and I did? cheers, Ben. _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com<http://www.ipexpert.com> Are you a CCNP or CCIE and looking for a job?
