Do you have video showing how to set up the underlying BGP network?

@orlasoe

The only BGP in the entire config is on the two PE routers, and is a iBGP neighborship.

The ISP is just using OSPF everywhere, in a single OSPF area.

Best wishes,

Keith

Thank you for the comments. I use SecureCRT (which is around $100), with a tab open to each of the routers. Putty (which is free) has a tool called Connection Manager (CM) which is also free, that lets you use tabs to switch between device as well.

Thanks,

Keith

@rhugswiss-

Regarding the typing speed: When I plan out a video, I prep the commands and have them ready. Sometimes I will do the audio separately (after the fact), and sometimes I will automate the scripts. My typing is about average, and I am thankful for spell checks!

Thanks for your comments, Keith.

1) To hide provider network from customers performs trace route, in global config mode of PE routers you need to type no mpls ip propagate-ttl forwarded .

2) Don't think so .

3) I second that. Really nice icons.

[XSFlanger]

That was really nice video. Hands on configuration is always more interesting and educational in my opinion! Got some questions as usual :)

1) How do you, as ISP, hide your IGP hops with MPLS labels from customers so they don't appear in their traceroute? I believe most ISP's hide this info.

2) Is it possible from customer to still observe hops mentioned above, using some kind of custom traceroute utility?

3) What software/icon set did you use to draw the diagram? Looks really great :)

Incredible video simple and straight to the point!!!

You talk way too quickly....wow.

really appreciate your approach and enthusiasm. in my graduate coures, I presented your materital to my grad. students, to help summarize MPLS and also showed your demo on the routers. I think it really helped to congeal the many concepts about routing protocols and versatility of MPLS from a provider's point of view. what tool do you use to switch between the routers?
