I'm currently doing a project to successfully end my apprenticeship.
I have some problems now.
In general, I want to simulate an DSL-connection between two routers.
Therefore I would need two DSL-Lines which I don't have available.
So I must at least simulate something like Internet an DSL.
I thought of an PPPOE-connection as a good candidate, as it allready is the real DSL-protocol type, which is used... but I can't work out the provider-side.
First of all you could take a look at the attachment.
As you can see I added a third router to the scenario, for simulation WAN or simply the internet.
Now I want to use PPPOE on both sides of this router and the WANrouter should provide static ip-addresses to his clients (llrouter, mlrouter).
Now I have several options which I can't figure out.
First, I created a dialer interface on both client-routers, set the MTU-size etc. including the ppp encapsulation.
I also have an vpdn-group with "request-dialin" set and protocol pppoe defined.
One question here is, how these both configurations are connected together.
I do understand the basic purpose of a "Virtual Private Dialup Network" but I don't see how the vpdn configuration does affect the overall configuration.
On which point of connection-establishment and traffic is the vpdn config actually used ?
Next questions would be the dialer pools and groups I defined in the dialer interface.
All I did was configuring "dialer pool 1" and "dialer-group 1".
But where can I configure further details to the pool or the group ?
Both configurations link to someplace called "1" which has never been defined anywhere.
Whats the purpose of that ?
Another thing which I don't get is the "ip address negotiated" configuration.
For my understanding its purpose is to automaticly assign an IP-adress from a server.
Just like DHCP, but over PPP.
So far, so good.
But here the trouble starts again:
How do I get the wan-router to distribute IP-Adresses over PPP ?
DHCP works fine: I have my defined pool and certain settings and everything works.
For PPP I can't find similar settings... what do I have to do ?
I have no idea how to configure the wanrouter to be "provider"-like.
And theres nothing I could find about that.
The hardware I used:
llrouter - 2621XM
wanrouter - 7204VXR
mlrouter - 1641
Can anyone help me with that ?
