1 Trunk接口
a Eth-trunk 以太网链路构成
b IP-Trunk POS接口构成，只能用HDLC封装
逐流负载分担：报文源目地址相同时从同一成员链路通过
逐包地址分担：以报文为单位从不同成员链路发送
2 IP-Trunk配置
R1与R2互联
R1
int IP-Trunk 1
undo shutdown
ip add 10.1.1.1 24
int Pos1/0/0
link-protocol hdlc
undo shutdown
ip-trunk 1
int Pos2/0/0
link-protocol hdlc
undo shutdown
ip-trunk 1
R2
int IP-Trunk 1
undo shutdown
ip add 10.1.1.2 24
int Pos1/0/0
link-protocol hdlc
undo shutdown
ip-trunk 1
int Pos2/0/0
link-protocol hdlc
undo shutdown
ip-trunk 1
3 PPPoE配置
通过以太网把多台主机连接到接入设备，能够提供与拨号上网类似的访问控制和计费功能
服务端R1与客户端R2互联
