SPRING-TE support in PCEP implementation

The traffic engineering (TE) capabilities of Source Packet Routing in Networking (SPRING) are supported in Path Computation Element Protocol (PCEP) sessions for the label-switched paths (LSPs) initiated by a Path Computation Element (PCE). Tunnel routes are created in the inet.3 routing table of the Path Computation Client (PCC) corresponding to the SPRING-TE LSPs. Similar to any other tunnel route, the SPRING-TE tunnel routes can be used for resolving indirect next hops for plain IP and service traffic.

To configure SPRING-TE for PCEP:

• Enable external path computing for MPLS and SPRING-TE at the [edit protocols] hierarchy level.
• Enable spring capability for the PCE at the [edit protocols pcep pce pce] hierarchy level.
