(VRRP configuration "Configuration Environment Parameters" SwitchA is connected to SwitchC through E0/24, SwitchB is connected to SwitchC through E0/23, and SwitchA is connected to SwitchC through E0/23 and SwitchA is connected to SwitchA through ethernet0/24 and ethernet0/24 of SwitchB. Create two virtual interfaces on SwitchB and interfacevlan10 and interface20 as Layer 3 interfaces. Interfacevlan10 includes ethernet0/24 ports respectively, and interface20 includes ethernet0/23 ports as egress. "Networking requirements" VRRP is used between SwitchA and SwitchB, interfacevlan10 is used as the virtual gateway interface, SwitchA is the master device, allowing preemption, SwitchB is the slave device, and the gateway of the PC1 host is set to the VRRP virtual gateway address 192.168.100.1 for redundancy. backup. Access the remote host PC210.1.1.1/24)
