All links have 1 Gbps unreserved bandwidth initially and all LSPs have the least-fill feature enabled. After the two LSPs have been signaled as shown, two additional LSPs are configured.
LSP-3 is signaled first with 50Mbps reserved. LSP-4 is signaled after with 400Mbps reserved.
Which paths will CSPF choose for LSP-3 and LSP-4?
