Configuration Examples for Link Fragmentation and Interleaving
Configuration Examples for PVC-Based FRF.12 Fragmentation
Example 16-19 shows how to use a map class to configure PVC-based FRF.12 Fragmentation and attach
the map class to a main interface. In the example, fragmentation is enabled in the map class named frag
and the fragment payload size is set at 40 bytes. The frag map class also enables weighted fair queuing
and has the QoS service policy named Bronze applied for outbound traffic. The frag map class is
associated with serial interface 1/0/0/1:0. The main interface has two subinterfaces configured:
subinterface 1/0/0/1:0.1 with DLCI 100 and subinterface 1/0/0/1:0.2 with DLCI 101. Because the frag
map class with fragmentation enabled is attached to the main interface, fragmentation is also enabled on
DLCI 100 and DLCI 101.
Example 16-19 Configuring PVC-Based FRF.12 Fragmentation on an Interface Using a Map Class
Router(config)# map-class frame-relay frag
Router(config-map-c)# frame-relay cir 128000
Router(config-map-c)# frame-relay bc 1280
Router(config-map-c)# frame-relay fragment 40
Router(config-map-c)# frame-relay fair-queue
Router(config-map-c)# service-policy output Bronze
Router(config-map-c)# no frame-relay adaptive-shaping

Router(config)# interface serial 1/0/0/1:0

Router(config-subif)# frame-relay interface-dlci 101
Example 16-20 shows how to use a map class to configure FRF.12 Fragmentation and attach the map
class to a subinterface. In the example, the fragmentation is enabled on the map class named lfi-class1
and the map class is attached to serial subinterface 5/0/0/1:0.1. The QoS service policy named Business
is also attached to subinterface 5/0/0/1:0.1. In this configuration, all of the traffic on
subinterface
5/0/0/1:0.1 and all of the DLCIs configured on the subinterface are subject to fragmentation
and interleaving.
Example 16-20 Configuring PVC-Based FRF.12 Fragmentation on a Subinterface Using a Map Class
Router(config)# map-class frame-relay lfi-class1
Router(config-map-c)# frame-relay fragment 300
Router(config-map-c)# no frame-relay adaptive-shaping
!
Router(config)# interface serial 5/0/0/1:0
Router(config-if)# hold-queue 4096 in
Router(config-if)# no ip address
Router(config-if)# no ip directed-broadcast
Router(config-if)# encapsulation frame-relay
!
Router(config)# interface serial 5/0/0/1:0.1 point-to-point
Router(config-subif)# ip address 192.168.10.1 255.255.255.0
