黑洞路由黑洞路由最好避开内部服务器映射的IP，否则在内部通过外部IP（通常由外部域名服务器给出）访问时会得不到结果，项目配置如上图所示。

(1)配置SwitchA enable conf t vlan 10 exit vlan 20 exit vlan 30 exit vlan 40 exit ip routing inter range f 0/1-5 switchport mode acc switchport acc vlan 10 exit inter range f 0/6-10 switchport mode acc switchport acc vlan 20 exit inter range f 0/11-15 switchport mode acc switchport acc vlan 30 exit inter f 0/24 switchport mode acc switchport acc vlan 100 exit inter vlan 10 ip add 192.168.1.1 255.255.255.0 no shut exit inter vlan 20 ip add 192.168.2.1 255.255.255.0 exit inter vlan 30 ip add 192.168.3.1 255.255.255.0 exit inter vlan 100 ip add 10.1.1.1 255.255.255.0 exit router rip ver 2 net 10.1.1.0 redis conn exit router rip

(2)配置RouterA enable conf t inter f 0/0 ip add 10.1.1.2 255.255.255.0 ip nat inside no shut exit inter f 0/1 ip add 202.1.1.1 255.255.255.0 ip nat outside no shut exit ip route 0.0.0.0 0.0.0.0 202.1.1.2 router rip ver 2 default ori net 10.1.1.0 exit ip nat in s stat 192.168.3.100 202.1.100.100
