PPP Multilink协议（MP）是PPP（点对点协议）的扩展， PPP Multilink具有绑定两条或多条同步串行连接的能力。在PPP协议中,可以将多个PPP链路捆绑起来,形成一条宽更大的PPP链路,成为PPP Multilink,即多链路PPP，所产生的虚拟连接拥有的带宽等于各条独立连接的带宽的总和。

      本次实训设备采用的是两台神州数码DCR-2855路由器，配置Mutlilink PPP捆绑，编号为10。路由器之间采用Chap认证，RT-1路由器帐号名为JTrouter，密码为2022dcn。RT-2路由器帐号名为FBrouter，密码为2022dcn。

操作步骤

一、RT-1配置：

Router_config#hostname RT-1

RT-1_config#int lo1

RT-1_config_l1#ip add 1.1.1.1 255.255.255.255

RT-1_config_l1#int multilink 10

RT-1_config_m10#ip add 10.100.100.1 255.255.255.252

RT-1_config_m10#ppp multilink

RT-1_config_m10#int s1/0

RT-1_config_s1/0#encapsulation ppp

RT-1_config_s1/0#physical-layer speed 64000

RT-1_config_s1/0#no sh

RT-1_config_s1/0#ppp multilink

RT-1_config_s1/0#multilink-group 10

RT-1_config_s1/0#int s1/1     

RT-1_config_s1/1#encapsulation ppp

RT-1_config_s1/1#no sh

RT-1_config#int multilink 10

RT-1_config_s1/0#ppp authentication chap

RT-1_config_s1/0#ppp chap hostname JTrouter           

RT-1_config_s1/0#ppp chap password 2022dcn

RT-1_config_s1/1#exi

RT-1_config#router ospf 10

RT-1_config_ospf_10#router-id 1.1.1.1

RT-1_config_ospf_10#network 1.1.1.1 255.255.255.255 area 0

RT-1_config_ospf_10#network 10.100.100.0 255.255.255.252 area 0

RT-1_config_ospf_10#end

RT-1#wr

二、RT-2配置：

Router_config#hostname RT-2

RT-2_config#int lo0

RT-2_config_l1#ip add 2.2.2.2 255.255.255.255

RT-2_config_l1#int multilink 10

RT-2_config_m10#ip add 10.100.100.2 255.255.255.252

RT-2_config_m10#ppp multilink

RT-2_config_m10#int s1/0

RT-2_config_s1/0#encapsulation ppp

RT-2_config_s1/0#physical-layer speed 64000

RT-2_config_s1/0#no sh

RT-2_config_s1/0#ppp multilink

RT-2_config_s1/0#multilink-group 10

RT-2_config_s1/0#int s1/1     

RT-2_config_s1/1#encapsulation ppp

RT-2_config_s1/1#no sh

RT-2_config_s1/1#ppp multilink

RT-2_config_s1/1#multilink-group 10

RT-2_config_s1/1#exi

RT-2_config#username JTrouter password 0 2022dcn

RT-2_config#aaa authentication ppp default local

RT-2_config#int multilink 10

RT-2_config_s1/0#ppp authentication chap

RT-2_config_s1/0#ppp chap hostname FBrouter           

RT-2_config_s1/0#ppp chap password 2022dcn

RT-2_config_s1/1#exi

RT-2_config#router ospf 10

RT-2_config_ospf_10#  router-id 2.2.2.2

RT-2_config_ospf_10# network 2.2.2.2 255.255.255.255 area 0

RT-2_config_ospf_10# network 10.100.100.0 255.255.255.252 area 20

RT-2_config_ospf_10#end

RT-2#wr
