CCNA & ICND2 Question:

What bit is normally marked when you send traffic above the CIR of a Frame Relay virtual circuit?

A) DA

B) DB

C) DC

D) DE

E) ARP

F) CLP


Answer: D
Frames that are marked as "discard eligible" should be discarded before other frames in a congested network. This allows for a basic prioritization mechanism in Frame Relay networks.

The Discard eligibility (DE) can be set the network cloud when traffic exceeds the CIR of a circuit.

The DE can also be set by the DTE device, such as a router, to indicate that the marked frame is of lesser importace relative to other frames being transmitted.
