There are two ways to connect two vrouters with a broadband network! In either case, the master route connected to the Internet is always the same! Just change the Slave Route settings! The public part assumes that you are using ADSL dial-up Internet access. There are two routes. Route A is the primary route, and Route B is the slave route! First, set the WAN port status of route A to the PPPoE dialing status, and then enter the account and password of the ADSL dialing. Then, set the LAN port IP address of route A to 192.168.1.1 and the IP address segment of the LAN port to 192.168.1.X. First. Slave Route is still used as a route! 1st. Set the WAN port status of Route B to static IP, and the IP address to 192.168.1.2 mask 255.255.255.0 to 192.168.1.1. 2nd. Set the LAN port IP address of Route B to 192.168.2.1 and the IP address segment of the LAN port to 192.168.2.X mask 255.255.255.0 3rd. Connect the WAN port of Route B and any LAN port of route A with A network cable. Second, routing is used by switches! 1st. Change the IP address of Route B to another CIDR block. For example, if most vro addresses are 192.168.1.1, we only need to change the IP address from a vro0.1 to 192.168.0.1; 2nd, then disable the dhcp function of the vro in the settings; 3rd, finally, connect the network cable from the primary router to the LAN port of the slave router (either way). Note that it cannot be a WAN port.
