Which two values influence how the fragment size should be set when configuring FRF.12? (Choose two.) (Exhibit)
A.
the physical interface port speed
B.
the dual FIFO Frame Relay interface queue size
C.
the CIR of the PVC
D.
the Voice over IP (VoIP) packet size
E.
the software queuing method
Explanation:
The purpose of end-to-end FRF.12 fragmentation is to support real-time and non-real-time data packets on lower-speed links without causing excessive delay to the real-time data. FRF.12 fragmentation is defined by the FRF.12 Implementation Agreement. This standard was developed to allow long data frames to be fragmented into smaller pieces (fragments) and interleaved with real-time frames. In this way, real-time and non-real-time data frames can be carried together on lower-speed links without causing excessive delay to the real-time traffic. End-to-end FRF.12 fragmentation is recommended for use on permanent virtual circuits (PVCs) that share links with other PVCs that are transporting voice and on PVCs transporting Voice over IP (VoIP). Although VoIP packets should not be fragmented, they can be interleaved with fragmented packets.
To configure the map class to support FRF.12 fragmentation, use the following map-class configuration command:
