What is an advantage of configuring subinterfaces in a Frame Relay environment?

  • It makes the DLCIs globally significant.
  • It eliminates the need for using Inverse ARP.
  • It solves split-horizon issues.
  • It improves flow control and bandwidth usage.

Explanation: When point-to-point subinterfaces are used, each VC is on a separate subnet; therefore, split horizon is not an issue. From the perspective of the router, each VC is on a separate (logical) interface. This eliminates split horizon as an issue.
