模拟器WVRP RouterVisio-V1.6.6-incl-WVRPV5R7
连接方式 R1--s0/0/0--------s0/0/0--R2--s0/0/1---------s0/0/0--R3
路由器1,2之间12网段,23之间23网段
R1上tunnel 0/0/0 (这个模拟器必须要这样的格式,不能直接tunnel 0)配置
ip address 192.168.1.1 255.255.255.252
tunnel-protocol gre
source 12.1.1.1
destination 23.1.1.3
gre checksum
R3上tunnel 0/0/0配置
ip address 192.168.1.2 255.255.255.252
tunnel-protocol gre
source 23.1.1.3
destination 12.1.1.1
gre checksum
测试公网可达性
