Routers and switches have several interfaces

See how to divide it, how many departments it is divided into, and then divide it as needed. The general mode is that the external network comes in, connects to the firewall (routing can also be used), then connects to the core, and then the core and then to the floor, and then adds a convergence between the core and the floor. For example, 500 switches are divided into five floors and one hundred on one floor, that is, three switches (two 48 ports and one 24 ports) are placed on the first floor, and these three switches are all connected to the core and go out through the core.

The difference is as follows: if you refer to a small household router, then connecting another switch is equivalent to expanding the number of LAN ports; If it is to connect another router, wait for the socks to open the socks, so expand a subnet.

If it is a high-end router and switch, it depends on your network structure, and the professional explanation is: the switch expands the range of a broadcast domain cavity, and the router is the interconnection of two networks.

Pros of the router:

Suitable for large-scale networks;

network topology, load sharing, and optimal paths;

can handle more ** better;

High level of security.

Summary. Hello, glad to answer for you! Switches and routers each require at least one IP address for management and configuration.

For switches, this IP address is called the "management IP address", and it is used to remotely manage the switch, including configuring ports, VLANs, and managing users. In most cases, the switch only needs a management IP address. However, in some cases, such as when stacking multiple switches, each switch may require a separate management IP address.

For routers, at least two IP addresses are required: one is the local interface IP address, which is the IP address of the router connecting to the local network; The other is the remote interface IP address, which is the IP address of that router connecting to other networks. These two IP addresses are often different and are used for data** and routing between different networks.

How many p addresses do switches and routers have?

Hello, glad to answer for you! Switches and routers each require at least one IP address for management and configuration. This IP address is called the "management IP address", which is used to remotely manage the switch, including configuring port monitoring and grouping, VLAN, and management users.

In most cases, the switch only needs a management IP address. However, in some cases, such as when stacking multiple switches, each switch may require a separate management IP address. For routers, at least two IP addresses are required:

One is the local interface IP address, that is, the IP address of the router connecting to the local network; The other is the remote interface IP address, which is the IP address of that router connecting to other networks. These two IP addresses are usually different and are used for incoming data** and routing between different networks. In some cases, routers may need more IP addresses, such as when routing between multiple subnets, each subnet needs to be assigned an IP address.

In general, switches usually have only one IP address, which is usually used for management purposes. Routers usually have at least two IP addresses: one for inside the local network and one for the external network (e.g. the Internet).

In addition, some of the Gateways may have additional IP addresses for management or other purposes.

The computer sends several devices to the switch without the p-address of the switch.

If 4 mouths are enough. Then you don't need a switch. The difference can be seen in the OSI reference model.
