EIGRPv6 Passive Interface.

What Is EIGRPv6 Passive Interface? EIGRPv6 Passive Interface refers to a specific configuration in Enhanced Interior Gateway Routing Protocol (EIGRP) for IPv6, where an interface is set to ‘passive’. This configuration prevents EIGRPv6 from sending or receiving routing updates on that interface, conserving network resources and bandwidth. It is commonly used on interfaces where EIGRPv6 routing information is… Read More »

EtherChannel Configuration on Cisco Switches.

By configuring EtherChannel, we bundle multiple physical connections between two or more Cisco switches into one logical link. This allows for increased bandwidth, improved fault tolerance, and load balancing across the aggregated links. EtherChannel also provides a more efficient use of available network resources and simplifies the management of network connections between switches. In a conventional network where… Read More »

Spanning Tree Protocol Types / Standards.

What are the Types of STP? The Spanning Tree Protocol (STP) standards are a set of network protocols that ensure a loop-free topology for Ethernet networks.The basic idea behind STP is to prevent network disruptions caused by loops, which are common in Ethernet networks. STP works by organizing the network’s switches into a hierarchy and blocking certain redundant… Read More »

Virtual Local Area Network -VLAN.

What Is a VLAN? VLAN (Virtual Local Network) is a logically separate IP subnetwork that allows multiple IP networks and subnets to exist on the same-switched network. VLAN is a logical broadcast domain that can span multiple physical LAN segments. It is a modern way administrators configure switches into virtual local-area networks (VLANs) to improve network performance by… Read More »

Understanding Wildcards / CIDR.

What Is IP Address Wildcards? An IP address wildcard is a method used in network configurations to specify a range of IP addresses. CIDR (Classless Inter-Domain Routing) is a method for allocating IP addresses and routing Internet Protocol packets. It was introduced in the early 1990s as a replacement for the traditional class-based IP addressing scheme, with the… Read More »
