Which protocol is used to communicate LSP and status information between the NorthStar Controller and label edge routers?

Answer options

• A. ICCP
• B. BGP
• C. PCEP
• D. OSPF

Correct answer: C

Explanation

The correct answer is C, PCEP, which is specifically designed for communication related to path computation and LSP management between controllers and label edge routers. ICCP, BGP, and OSPF serve different purposes, such as inter-controller communication, routing information exchange, and link-state routing, respectively, and are not focused on LSP management.
