Notes on layer-3 switch of linux Network

1: a layer-3 switch can solve the single-arm routing traffic bottleneck problem, mainly through one route multiple exchanges.

2: Layer-3 switch principle: Find the mac address and the target mac address once through the route table, and then record the mac address and the target mac address to form a ing relationship between the route table and the arp table, in the future, data will be directly forwarded through hardware when different VLANs are exchanged.

3: a layer-3 switch can configure a route table and create a virtual vlan to configure the corresponding vlan gateway.

4: The ip address of the vlan configured for the switch is for remote management of the switch. the ip virtual ports of the switch in the Lan are configured as the same vlan.

5: each vlan has a mac address.
