GNS環(huán)境下做vrr實(shí)驗(yàn)

1、VRRF實(shí)驗(yàn)在這個(gè)實(shí)驗(yàn)配置了兩個(gè)VRRPSvrrp 1和vrrp 2。在vrrp 1中，路由器R1為主虛擬路由器，R2為備用虛擬路由器；在 vrrp 2中，路由器R1為備用虛擬路由 器，路由器R1為主虛擬路由器。在兩個(gè)路由器都正常工作的時(shí)候，PC1和PC2通過 R1 訪問遠(yuǎn)端 R3。路由器 R1 的具體配置：R1(config-if)#int s1/0R1(config-if)#no shutdownR1(config-if)#int f0/0R1(config-if)#no shutdownR1(config-if)#vrrp 1 priority 200/ Priority change
