二：实验要求:
在 R2上基于PVC来分配带宽，PVC201可以分得20％的带宽，PVC203分得55％的带宽
三：实验配置:
R1#
interface Loopback0
ip address
interface Serial3/0
ip address 123.0.0.1 255.255.255.0
encapsulation frame-relay
ip ospf priority 0
frame-relay map ip 123.0.0.2 102 broadcast
frame-relay map ip 123.0.0.3 102 broadcast
no frame-relay inverse-arp
router ospf 1
network
R2#
class-map match-all PVC203 //步骤1 建立一个class map来表示网络流量
match fr-dlci 203 //指定DLCI号作为匹配标准
class-map match-all PVC201
match fr-dlci 201
policy-map PVC //步骤2 创建一个policy map
class PVC201
bandwidth percent 20
class PVC203 // 应用class map到policy map中
bandwidth percent 55 // 设定带宽的百分比
interface Loopback0
ip address
interface Serial3/0
encapsulation frame-relay
no frame-relay inverse-arp
service-policy output PVC //步骤3 把policy map绑定到接口的出方向
