Configuring Frame Relay
Multi-point to Point-to-Point Example
The following example configures the XSR in New York to connect with XSRs in Andover and
Montreal using Frame Relay, as shown in
Figure 9-4 .
Figure 9-4 Frame Relay Multipoint to Point-to-Point Topology
The following CLI commands enable the sample multipoint to point-to-point configuration
pictured above. At the New York site, multipoint networks with a 64 Kbps-PVC are configured to
Andover and Montreal. The line rate of New York is 128 Kbps and 64 Kbps at both Andover and
Montreal.
Begin configuration on the New York XSR by creating the QoS class maps Tos4, EF, and AF1 with
IP precedence and DSCP classification match criteria:
NewYork(config)#class-map Tos4
NewYork(config-cmap)#match ip precedence 4
NewYork(config-cmap)#class-map EF
NewYork(config-cmap)#match ip dscp 46
NewYork(config-cmap)#class-map match-any AF1
NewYork(config-cmap)#match ip dscp 10
NewYork(config-cmap)#match ip dscp 12
NewYork(config-cmap)#match ip dscp 14
Configure the QoS policy map Voice with scheduling and bandwidth policy criteria for the EF,
Tos4, AF1 class maps:
NewYork(config-cmap)#policy-map Voice
NewYork(config-pmap)#class EF
NewYork(config-pmap-c)#priority high 2
NewYork(config-pmap-c)#class Tos4
NewYork(config-pmap-c)#priority medium 48
NewYork(config-pmap-c)#class AF1
NewYork(config-pmap-c)#bandwidth percent 20
Configure the QoS policy map frf12 with burst, CIR and fragmentation values. Also, assign the
Voice QoS service policy to the output of the interface (Serial 2/0) you will configure in the next
section.
NewYork(config)#map-class frame-relay frf12
NewYork(config-map-class)#frame-relay cir out 32000
