PCEP session over IPv6

We've extended the Path Computation Element Protocol (PCEP) session management over IPv6. With this support, Path Computation Client (PCC) and Path Computation Element (PCE) can establish an IPv6 session with or without TCP MD5 hash. Junos OS can set up an IPv6 PCEP session with NorthStar, Paragon Pathfinder, or a third-party controller if it is capable of establishing an IPv6 session. The IPv6 session supports functionalities such as PCE-provisioned LSPs, PCE-delegated LSPs, router-controlled LSPs, and LSP synchronization over an IPv6 PCEP session with or without MD5 security. You cannot configure PCE with both IPv4 address and IPv6 address; only one address format is supported at a time.
