How can you ensure that there is no overlap in IP addresses when remotely connecting two networks? In this video, explore using virtual forwarding instances in your MPLS domain.
- In the NRC blueprint from Cisco, … we're told that we need to be able to describe … an MPLS Layer 3 VPN. … The actual configuration of an MPLS Layer 3 VPN … is actually outside of the scope of this particular exam. … But you do need to know the fundamental principles involved. … So we want to take a look at that here. … Here you can see we have a service provider cloud … containing two internal routers labeled P1 and P2. … And at the edge of this cloud, … we of course have Provider Edge routers labeled PE1 and PE2. … These each connect into our Customer Edge routers. … And we have four of those … at the edge of our customer clouds. … You can see we have two companies … with two different locations. … We have Customer A, Site 1 and Site 2 … and we have Customer B with Site 1 and Site 2. … Now the entire reason we use VPNs … are that they allow us to emulate point to point connections … so that we don't require a dedicated link. … So this is much more cost effective and scalable. … Remember MPLS uses labels to make forwarding decisions …
