Three layer 3 switches interconnected, how to let the three is not an IP segment computer connected? Who is a great god will, please leave the order, I learn

Well,,, dividing vlan set port?

CodePudding user response:

Don't set the IP, no gateway,,,, the PC can not access the

Yes, that is to say, use what commands let him

CodePudding user response:

One layer 3 switches, routing functions, the other two as a layer 2 switch is used,

The three switches is now a loop, there may be a broadcast storm, the need to build the STP, zha do?

The configuration vlan and vlanif ah

CodePudding user response:

There is no loop, three switch when routers use
1. The first configuration terminal equipment (PC) 2. To configure the routing exchange equipment 3. Verify

CodePudding user response:

Switch is open the STP function by default, three switches interconnected also won't produce loop,
One will have a switch port is blocked,
This will affect the establishment of the OSPF neighbor, so the best turn off three switch function of STP,
