R1上做rip学习到的网段：
Router(config)# do show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

R 50.0.0.0/8 [120/1] via 70.0.0.1, 00:00:26, FastEthernet2/0
[120/1] via 60.0.0.1, 00:00:21, FastEthernet1/0
C 70.0.0.0/8 is directly connected, FastEthernet2/0
R 20.0.0.0/8 [120/1] via 70.0.0.1, 00:00:26, FastEthernet2/0

获取dhcp：

VPCS 2 >dhcp
DORA, IP 20.0.0.1/8 GW 20.0.0.10

VPCS 2 >dhcp
DORA, IP 20.0.0.1/8 GW 20.0.0.10

VPCS 2 >3
VPCS 3 >dhcp
DDORRR
Can't get ip address from dhcp server

VPCS 3 >dhcp
DORA, IP 20.0.0.2/8 GW 20.0.0.10

这个实验运用到的知识点：以太网通道、vtp、hsrp、spanning tree、dhcp、dhcp中继
