Why Is BGP the King of Routing Protocols?
by PivIT Global on Jun 14, 2022 7:12:00 AM
Routers must be aware of all networks within the enterprise premises and the available routes to reach them to provide full network connectivity. For that purpose, routing protocols are used such as OSPF, EIGRP, or RIP, to dynamically exchange information and perform appropriate recal …

What Is a GRE Tunnel and How Do You Configure One?
by PivIT Global on Jun 7, 2022 7:04:00 AM
Generic Routing Encapsulation (GRE) is a tunneling protocol for exchanging encapsulated data packets over an established tunnel. In other words, GRE creates a virtual point-to-point link between two devices in separate networks that need to communicate with each other.` The whole proc …
Back to the Basics: Is Static or Dynamic Routing Better?
by PivIT Global on Jun 2, 2022 7:04:00 AM
The TL;DR of this question: Neither. They're just different. Read on to learn when to use each routing solution. Routers are an essential piece of hardware in networks. They preserve the knowledge of the network topology and use that information to forward packets to each destination. …
Best Practices for Switch Stacking Configuration
by PivIT Global on May 31, 2022 9:53:51 AM
What Is Switch Stacking? Switch Stacking physically connects multiple switches into one logical switch. The switches will appear as one and interact together as if they were one large switch. Traditionally, when additional ports were needed, you would have to upgrade to a larger switc …

by PivIT Global on May 26, 2022 7:21:57 AM
A Dynamic Host Configuration Protocol (DHCP) in a network is a common approach to allocating IP information dynamically to clients as they shift from one network to another within an enterprise.
OSPF Configuration (Pt. 2) – Misc. Features and Multi-Area Configuration
by PivIT Global on May 6, 2022 11:48:46 AM
OSPF can be implemented by using two different approaches, single-area or multi-area deployment. In a single-area design, all routers are part of the same area and are an appropriate option for small networks. Let’s not forget that in such a scenario many link-state advertisements (LS …
Interior Routing Protocols Comparison: RIP vs EIGRP vs OSPF vs IS-IS
by PivIT Global on May 6, 2022 11:07:18 AM
Using a dynamic routing protocol in a network today is a common routing strategy for providing full network connectivity in enterprise environments. Simultaneously, it has many advantages over static routing and brings many additional benefits, especially in medium to large networks.
