What is IS-IS?
IS-IS (Intermediate System to Intermediate System) is a link-state routing protocol used within an autonomous system (a network under a single administrative control). It's primarily used by Internet Service Providers (ISPs) and large enterprise networks to efficiently route IP packets based on network topology. IS-IS determines the best path for data based on metrics like bandwidth and delay, offering fast convergence and scalability.

BGP is used for inter-domain routing, while IS-IS is an intra-domain routing protocol. They work together in a network.
MPLS
MPLS can use IS-IS as the underlying routing protocol to distribute labels and establish paths.
LDP
LDP is often used in conjunction with IS-IS to distribute labels in an MPLS network, although alternatives like RSVP-TE and Segment Routing exist.
