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

New York	XSR	Andover
multipoint subnet 1
(10.10.10.1) to remote sites		10.10.10.2
		dlci: 980
Andover (dlci: 980, CIR: 32 Kbps
		Line rate: 64 Kbps
Montreal (dlci: 960, CIR: 32 Kbps)
Line rate: 128 Kbps
XSR	XSR
Frame Relay		Montreal
Network		10.10.10.3
		dlci: 960
		Line rate: 64 Kbps

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<Tos4>)#match ip precedence 4

NewYork(config-cmap<Tos4>)#class-map EF

NewYork(config-cmap<EF>)#match ip dscp 46

NewYork(config-cmap<EF>)#class-map match-any AF1

NewYork(config-cmap<AF1>)#match ip dscp 10

NewYork(config-cmap<AF1>)#match ip dscp 12

NewYork(config-cmap<AF1>)#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<AF1>)#policy-map Voice

NewYork(config-pmap<Voice>)#class EF

NewYork(config-pmap-c<EF>)#priority high 2

NewYork(config-pmap-c<EF>)#class Tos4

NewYork(config-pmap-c<Tos4>)#priority medium 48

NewYork(config-pmap-c<Tos4>)#class AF1

NewYork(config-pmap-c<AF1>)#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<frf12>)#frame-relay cir out 32000
