H3C设备之 PPP
PPP配置：
配置路由器使用广域网封装协议：PPP<H3C路由器默认广域网接口封装方式>：
[RTA]int e0/0
[RTA-Ethernet0/0]ip add 192.168.1.1 24
[RTA]int s0/0
[RTA-s0/0]ip add 10.1.1.1 24
[RTB]int e0/0
[RTB-Ethernet0/0]ip add 192.168.2.1 24
[RTB]int s0/0
[RTB-s0/0]ip add 10.1.1.2 24
PCA:192.168.1.2 255.255.255.0 GT:192.168.1.1
PCB:192.168.2.2 255.255.255.0 GT:192.168.2.1
[RTA]ip route-static 192.168.2.0 255.255.255.0 10.1.1.2
[RTB]ip route-static 192.168.1.0 255.255.255.0 10.1.1.1
此时PCA和PCB可以互访：

在RTA RTB S0/0接口上启用PPP协议：
RTA]int s0/0
[RTA-s0/0]link-protocol ppp
[RTA-s0/0]buadrate 9600
[RTB]int s0/0
[RTB-s0/0]link-protocol ppp
[RTA]disp int s0/0/0
Serial0/0/0 current state: UP
Line protocol current state: UP
