What is an MPLS LDP targeted session?

An MPLS LDP targeted session is a label distribution session established between two Label Switch Routers (LSRs) that are not directly connected. This is achieved by explicitly configuring the IP addresses of the remote LSRs, allowing LDP to establish a TCP connection over multiple hops. This is useful for scenarios like MPLS VPNs where Provider Edge (PE) routers need to exchange labels for VPN routes with other PEs across the core network, even if they are not adjacent. The other options describe standard LDP discovery (multicast hello packets for directly connected neighbors) or general LDP session characteristics, not the specific "targeted" aspect.
