1.拓扑图如下
- RTB配置dhcp服务器
[RTB]dhcp enable
[RTB]dhcp server ip-pool 1
[RTB-dhcp-pool-1]network 10.1.1.0 24
[RTB-dhcp-pool-1]gateway-list 10.1.1.1
2.RTA的ip地址使用dhcp动态获取
[RTA-GigabitEthernet0/0]ip address dhcp-alloc
[RTA]display interface brief
Brief information on interfaces in route mode:
Link: ADM - administratively down; Stby - standby
Protocol: (s) - spoofing
