MPLS L3VPN Configuration - Internet Access

[@kevinallamby9730]

Nick, that for such great videos, they very informative and in most part, easy to follow. Only issue I am having is I am not seeing any NAT translations on the INTERNET router but the Customers routers can ping the internet and site-to-site networks. Could it be because my g0/0 is getting an IP address in 192.168.x.x private address range?

Hello Kevin, have you setup NAT on the INTERNET Router? It’s worth making sure your ACL is setup to cover the public IP ranges to ensure the translation takes place. If the CE routers are able to connect to the internet then it sounds like NAT is working or not required on the INTERNET router. Hope this helps. Thanks Nick

What do I need to do to be able to let the LAN side (Loopback 0) ping the Internet? I see you can only ping the Internet from the sub-interface that was made.

You need to achieve this with routing and NAT. So your default route uses the internet subinterface and you NAT to that IP too. Hope this helps

Nick, thanks for all your videos; they have been very helpful. I am however having some problem with this particular demo. It would help if you could tell me what configurations currently reside on customer routers, PE1 router and the PE routers. I followed your steps but am not able to get the correct results. My starting point was where you stopped in the earlier videos, which was MPLS with static routes. Thanks for your help.

Hello, I believe the setup of this video was the first MPLS L3VPN video I created and the video about using BGP for the PE-to-CE routing protocol. You shouldn’t need to follow the subsequent videos as they are about changing the routing protocol used with the customer. This video uses BGP as the PE-to-CE routing protocol. Hope this helps. Thanks Nick
