Why do I have multiple network interfaces?

Why do I have multiple network interfaces?

Multiple network interfaces enable you to create configurations in which an instance connects directly to several VPC networks. Each of the interfaces must have an internal IP address, and each interface can also have an external IP address. Each interface on a VM is affected by the MTU of the attached network.

What is a broadcast domain in networking?

A broadcast domain is a logical division of a computer network, in which all nodes can reach each other by broadcast at the data link layer. A broadcast domain can be within the same LAN segment or it can be bridged to other LAN segments. Routers and other higher-layer devices form boundaries between broadcast domains.

What is the maximum number of virtual Lans allowed per physical interface?

4094 VLANs

Why is there a 2 after my network name?

How are subnets different from a single network?

Subnets are the logical groups of addresses that we use to separate networks. A single network can also be subnetted. Subnetting takes a single network and subdivides it into smaller networks. Why would I do it?

How are subnets and VLANs used in a network?

For enterprise networks, subnets and VLANs are often used in conjunction to work on the network’s different broadcast layers. VLANs also mean your network isn’t tied to specific hardware.

Can a router be used for more than one network?

But given the headaches of deploying and maintaining just a single network on a router, many network admins – or just those managing networks at home – tend to shy away from configuring multiple LANs on a single router. Before we dive into how to configure multiple networks on a single router, let’s talk about why it can be beneficial.
