class to a Frame Relay DLCI. In the example, fragmentation is enabled in the Frame Relay map class
named Voice and the fragment size is set at 320 bytes. The Voice map class also enables priority queuing.
The policy map named Business is also applied to the Voice map class. The map class is attached to
DLCI 20 configured on the point-to-point serial subinterface 7/0/0/1:0.1.
Example 16-21 Configuring PVC-Based FRF.12 Fragmentation on a DLCI Using a Map Class
Router(config)# map-class frame-relay Voice
Router(config-map-c)# frame-relay fragment 320
Router(config-map-c)# frame-relay ip rtp priority 16384 16383 25
Router(config-map-c)# service-policy output Business
Router(config-map-c)# exit

Router(config-fr-dlci)# frame-relay class Voice

Configuration Example for Interface-Based FRF.12 Fragmentation

Example 16-22
example, the fragment size is set at 300 bytes. The service policy named 11q is attached to the serial
interface 3/00/0.1/1:0 and applied to the outbound packets on the main interface, subinterface, and
DLCIs. Because fragmentation is enabled directly on the main interface, all of the traffic on the main
interface, the subinterfaces, and the DLCIs is subject to fragmentation and interleaving.
Example 16-22 Configuring Interface-Based FRF.12 Fragmentation
Router(config)# access-list 101 match ip any host 10.16.0.2
Router(config)# class-map voice
Router(config-cmap)# match access-group 101
!
Router(config)# policy-map llq
Router(config-pmap)# class voice
Router(config-pmap-c)# priority
Router(config-pmap-c)# police 64000
Router(config-pmap-c)# class video
Router(config-pmap-c)# bandwidth 32
!
Router(config)# interface serial 3/0/0.1/1:0
Router(config-if)# hold-queue 4096 in
Router(config-if)# ip address 10.16.0.1 255.0.0.0
Router(config-if)# encapsulation frame-relay
