Which of the following statements regarding BGP shortcuts is FALSE?

BGP Shortcuts Concept: BGP shortcuts leverage MPLS tunnels to carry transit traffic efficiently across the network, reducing the need for full-mesh iBGP peering.

Statement Analysis:

Option A: Correct. MPLS tunnels are indeed used to carry transit traffic across the network.

Option B: Correct. A full mesh of iBGP peering sessions is not required when using BGP shortcuts.

Option C: Incorrect. Only edge routers need to be configured with BGP. Transit routers only need to support MPLS (LDP or RSVP-TE) but do not need to run BGP.

Option D: Correct. Transit routers need to support LDP (Label Distribution Protocol) or RSVP-TE (Resource Reservation Protocol-Traffic Engineering) LSPs (Label Switched Paths).

Conclusion: Option C is false because transit routers do not need to be configured with BGP.
