Task

• The connection between R3 and R5 is used to send data and voice traffic.
• Configure Frame Relay fragmentation so that voice packets are never delayed for more than 10ms when serialized.
• Assume the speed of R3’s connection is 384Kbps

Configuration

Rack1R3#
map-class frame-relay TO_R5
frame-relay fragment 480
!
interface Serial 1/0
no ip mtu
Rack1R5#
map-class frame-relay TO_R3
frame-relay fragment 480
!
interface Serial 0/0
no ip mtu

Verification

Rack1R3#show frame-relay pvc 305
PVC Statistics for interface Serial1/0 (Frame Relay DTE)
DLCI = 305, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial1/0
