Getting start with RSVP
We’ve spent a great deal of time in the last few posts talking about MPLS both with LDP and with static LSP configurations. While these approaches certainly work, they aren’t the only options to use for label distribution and LSP creation. If we take static LSPs off the table (since they’re the equivalent of static routes and not scalable) we really have two main choices for label distribution – LDP and RSVP. LDP is typically considered to be the easiest of the two options but also offers a limited set of functionality. RSVP offers many more features but also requires more configuration. When you’re designing an MPLS network you’ll have to decide which protocol to use based on your requirements. In many cases a network may leverage both in different areas. In this post the aim is just to get RSVP up and running – we’ll dig into the specifics in a later post.
So let’s get right into a simple lab where we leverage RSVP instead of LDP. Like the previous post, we’ll leverage the same lab environment…
Let’s assume as before that the base configuration of the lab includes all the routers interfaces configured, OSPF enabled on all Continue reading
