A VLAN is a sub-group within a network, which partitions and isolates network traffic at the data link layer (Layer 2) of the OSI model. VLANs are used to segment networks for… Read More »

IP Address Route Summary Explained with Examples.

What is IP Address Route Summary? IP Address route summation; which is also known as route aggregation, is the process routers use in advertising volume or set of IP addresses as a single address with a shorter subnet mask (CIDR). Route summarization allows engineers to configure a routing protocol so that it advertises one route, replacing several smaller… Read More »

IP Subnetting Explained with Examples.

IP Subnet allows you to create multiple logical networks that exist within a single Class A, B, or C network. In IP Subnetting, you can divide a large network into smaller subnetworks, which can improve overall network performance and security. Subnetting also helps in optimizing the allocation of IP addresses and efficiently using available address space. By segmenting… Read More »

IPv6 ACLs Explained with Examples.

What is IPv6 ACLs? There are similarities in the operation and configuration of IPv6 ACLs and its predecessor IPv4 ACLs. If you are familiar with the basic operation and configuration of the IPv4 access controls list, you will find  IPv6 ACLs easy to understand and configure too, the only difference is just the IPv6 addressing. An IPv6 Access… Read More »
