Marko,

Are you referring to the working or not working config?  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.

Then your configuration is not correct :-)

Did the task tell you to self-assign IPs using local pools, or was the
server supposed to assign IP to a client?

Could you copy your exact configuration here, please? Physical
interfaces, Virtual-Template, Dialer interface and OSPF process.
Thanks.

Hi Experts,

In Volume 2 Lab6 there is a requirement to run OSPF over a PPPoE session 
between R1 and R2.  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.
