MPLS Topology 1.2

Hopefully this will be my final tweak. This time I’ve added base configs to the CPE devices. It just gives them a hostname and ensures there is no timeout. This prevents you from having to keep logging back in.

Image-wise, it’s the same. Click for the larger image:

  1. Hi Darren,

    Thanks for sharing.
    I will have my CCIE lab test on early Feb.
    I can’t seem to find that many documentation nor tutorial for MPLS CCIE LAB.
    I bet your blog would help me a lot.
    Thanks

    Ian

  2. Hi Darren

    ı have some problem with dynamips to start all of router. Do you any advice about that?
