While I was doing some BGP labs I came across an interesting topic which is BGP over GRE. Using automatic tunneling techniques along with BGP is the core of MPLS VPNs and I think it is worth seeing the effect of using manual tunnels along with BGP. Let´s have a look at the following topology which illustrates my example:
It has been a while since I haven´t written in the blog but I have been busy with work and training.
I have now completed my BGP and MPLS exam which will give me a solid understanding for my CCIE training.
In order to pass these 2 exams I have used the student and lab guides from Cisco. I have done all the labs using real device as well as GNS3 (especially for MPLS where I used 13 routers!)
I attach the network diagram I used for MPLS training.
