Label distribution protocol (LDP) and resource reservation protocol (RSVP) explained

“

- [Instructor] Welcome back to the MPLS fundamentals section of the MPLS layer three VPN Foundation and Implementation course. This is the second video, Label Distribution Protocols: LDP and RSVP Explained. By the end, you will understand how LDP and RSVP defer and day roles in assigning labels in MPLS networks. Let's explore these protocols. In MPLS, labels steer packets, but how do routers know which labels to use? That's the job of label distribution protocols. Two key ones stand out. LDP, Label Distribution Protocol, and RSVP, Resource Reservation Protocol. They both assign labels, but they are built for different purposes. And in this course, we will focus on LDP for MPS layer three VPNs. First, LDP. It's simple and ties directly to IP routing. NDP shares labels with neighboring routers based on the routing table. When a route is learned, a label is assigned and passed along. It's automatic and efficient, making it the go-to for applications like MPLS L3VPNs, which we are diving…
