Initially, all links have 800Mbps of unreserved bandwidth. All links are of equal costs. Shared explicit reservation style is used. LSP 1 is signaled first with a setup and hold priority of 2. Then, LSP 2 is signaled with setup and hold priority of 5. Both LSPs go from R1 to R5. Which of the following is TRUE?
