二.基本配置：
A.SW1：
①创建VLAN
vlan database
vlan 11
vlan 12
 exit
②接口划入VLAN
interface FastEthernet0/1
 switch mode access
 switchport access vlan 11
 no shut
interface FastEthernet0/2
 switch mode access
 switchport access vlan 12
 no shut
③trunk接口配置
interface FastEthernet0/0
 sw trunk encapsulation dot1q
 switchport mode trunk
 no shut
B.R1：
①创建VRF
ip vrf vd01
 rd 1:1
ip vrf vd02
 rd 2:2
②划分子接口，并将子接口划分到vrf中
---处于不同vrf的子接口IP可以相同
interface FastEthernet0/0
 no shut
interface FastEthernet0/0.11
 encapsulation dot1Q 11
 ip vrf forwarding vd01
 ip address 10.1.1.1 255.255.255.0
interface FastEthernet0/0.12
 encapsulation dot1Q 12
 ip vrf forwarding vd02
 ip address 10.1.1.1 255.255.255.0
interface FastEthernet1/0
 no shut
interface FastEthernet1/0.21
 encapsulation dot1Q 21
 ip vrf forwarding vd01
 ip address 202.100.1.1 255.255.255.0
interface FastEthernet1/0.22
 encapsulation dot1Q 22
 ip vrf forwarding vd02
 ip address 202.100.1.1 255.255.255.0
③测试：
1.路由器能ping通VRF的接口地址
R1#ping vrf vd01 10.1.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 ms
R1#
R1#ping vrf vd02 10.1.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
R1#
R1#ping vrf vd01 202.100.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 202.100.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
R1#ping vrf vd02 202.100.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 202.100.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 ms
R1#
2.两个VPC配置相同的地址，都能ping通路由器的子接口地址
 
C.R2：
①创建VRF
ip vrf vd01
 rd 1:1
ip vrf vd02
 rd 2:2
②划分子接口，并将子接口划分到vrf中
---处于不同vrf的子接口IP可以相同
interface FastEthernet0/0
 no shut
interface FastEthernet0/0.11
 encapsulation dot1Q 11
 ip vrf forwarding vd01
 ip address 20.1.1.1 255.255.255.0
interface FastEthernet0/0.12
 encapsulation dot1Q 12
 ip vrf forwarding vd02
 ip address 20.1.1.1 255.255.255.0
interface FastEthernet1/0
 no shut
interface FastEthernet1/0.21
 encapsulation dot1Q 21
 ip vrf forwarding vd01
 ip address 202.100.1.2 255.255.255.0
interface FastEthernet1/0.22
 encapsulation dot1Q 22
 ip vrf forwarding vd02
 ip address 202.100.1.2 255.255.255.0
③测试：
R2#ping vrf vd01 202.100.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 202.100.1.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 20/42/80 ms
R2#ping vrf vd02 202.100.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 202.100.1.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 36/53/80 ms
R2#
---R2能ping通R2的相连的子接口地址
D.SW2：
①创建VLAN
vlan database
vlan 11
vlan 12
 exit
②接口划入VLAN
interface FastEthernet0/1
 switch mode access
 switchport access vlan 11
 no shut
interface FastEthernet0/2
 switch mode access
 switchport access vlan 12
 no shut
③trunk接口配置
interface FastEthernet0/0
 sw trunk encapsulation dot1q
 switchport mode trunk
 no shut
④测试：
VPC3和VPC4配置相同ip地址能ping通路由器的子接口地址
 
三.VRF静态路由配置：
A.R1：
ip route vrf vd01 20.1.1.0 255.255.255.0 202.100.1.2
ip route vrf vd02 20.1.1.0 255.255.255.0 202.100.1.2
B.R2：
ip route vrf vd01 10.1.1.0 255.255.255.0 202.100.1.1
ip route vrf vd02 10.1.1.0 255.255.255.0 202.100.1.1
四.效果测试：
VPC1能ping通VPC3，VPC2能ping通VPC4
