I am trying to setup a mock network in GNS3 to play around with MPLS, etc. I have the following configs but can’t seem to get PPPoE to work over my VPLS tunnels. I can ping all routers interfaces, loopbacks, etc from the endpoint client when I assign it a static IP address but can’t get it to see a PPPoE server. As well, if I connect the client (Ubuntu VM) to the main switch in the middle I can use pppoeconf to find the PPPoE server. This is what leads me to believe that the VPLS tunnels aren’t working correctly, or even the MTU. From what I have read a VPLS tunnel should act as if there was an Ethernet cable plugged in end to end.
If anyone has any suggestions or if I am missing anything please let me know. I haven’t done anything with VPLS in the real world, this is all just from what I have read online and watched about the MUMs on the topic.
The logical layout is as follows (Tower2 isn’t even configured yet).
