Inter-VLAN routing is the ability to route, or send, traffic between VLANs that are normally blocked by default. Switches and VLANs work at the MAC address Layer (Layer 2). Traffic can’t be routed between VLANs at Layer 2 based on MAC addresses....
Layer 2 switch provides connectivity between two or more different devices within a local area network. Switch allow data transfer between end devices in a network. When the data packet is for out of LAN, the packet sent to the gateway router. A...
A VLAN is a group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of...
Switching is process to forward packets coming in from one port to a port leading towards the destination. When data comes on a port it is called ingress, and when data leaves a port or goes out it is called egress. A communication system may...
let’s configure DNS server. Perform this task to configure the device as a DNS server. A Cisco IOS device can provide service to DNS clients, acting as both a caching name server and as an authoritative name server for its own local host...
The internet has become an integral part of our lives, allowing us to access information, connect with others, and conduct business transactions seamlessly. Behind the scenes, numerous systems work together to ensure this smooth operation. One such...
An Internet Protocol Version 6 address (IPv6 address) is a numerical label that is used to identify a network interface of a computer or a network node participating in an IPv6 computer network and for locating it in the network. IP addresses are...
Private IP’s were originally meant as a more secure means of providing IPv4 addresses to devices because private IP’s are not routable over the internet. You do have to turn them into some sort of public address if you want to route over...
Communication between hosts can happen only if they can identify each other on the network. In a single collision domain (where every packet sent on the segment by one host is heard by every other host) hosts can communicate directly via MAC...
The key difference between TCP and UDP is that TCP provides a wide variety of services to applications, whereas UDP does not. For example, routers discard packets for many reasons, including bit errors, congestion, and instances in which no correct...
