A router uses a systematic process to determine the best route for forwarding a data packet. This process involves several key factors: longest match, administrative distance, and routing protocol metric. Below is a detailed explanation of each factor and how they contribute to the routing decision: 1. Longest Match The longest match principle means that the router selects… Read More »
Routing Information Protocol Version 2 – RIPv2. RIPv2 is a classless, distance vector routing protocol as defined in RFC 1723. Being a classless routing protocol, means, it includes the subnet mask with the network addresses in its routing updates. As with other classless routing protocols, RIPv2 supports CIDR supernets, VLSM and discontiguous networks. Due to the deficiencies of RIPv1, RIP version 2 (RIPv2) was developed in… Read More »
CCNA v6.0 – How to configure RIP v2 on a Network. As you must have known…RIPv2 is a classless, distance vector routing protocol as defined in RFC 1723. Being a classless routing protocol, means, it includes the subnet mask with the network addresses in its routing updates. Read More on RIPv2 On this page, we’ll look at: * Configuring RIP v2… Read More »
What is the Spanning Tree Protocol (STP)? STP is used by switches to prevent loops from occurring on a network, this process is implemented by using the spanning tree algorithm to disable unwanted links and blocking ports that could cause a loop. Here are the key points about STP: Purpose: In a network with multiple paths between switches,… Read More »
What Is Multi-Area OSPFv3? Before we look at Multi-area OSPF, you must understand OSPF single-area concepts and configuration. OSPF (Open Shortest Path First) is a classless (supports VLSM and CIDR.), Link State Routing Protocol with an Administrative distance (AD) of 110. OSPF is more efficient than distant vector routing protocols, any routing changes trigger OSPF routing updates which are propagated… Read More »
