Read moreBGP Labeled-Unicast is the key to making Interprovider Option C work. So, before we learn how to use Option C to extend an MPLS VPn between two ISPs, let’s learn all about this interesting address family. And if you like, we can even hold hands while we learn!
Read moreLet’s learn how to stretch an MPLS VPN between ISPs using a thing called “Option B”. It involves a little bit of trust between the ISPs – but as we’ll see, it greatly reduces the complexity in configuration!
Read moreHey there: you smell good! That’s probably because you just read Part 1 of this two-part blog post, where we learned all about BGP communities, and how route-targets are used in MPLS VPNs. Well, now you know the theory, let’s look at a problem ticket. Click here to read Part 2!
