How To Troubleshoot and Verify EIGRP Configuration Examples.

EIGRP, or Enhanced Interior Gateway Routing Protocol, is a Cisco proprietary routing protocol designed for use within an autonomous system (AS) in an IP network. It is an advanced and efficient routing protocol that combines the benefits of distance vector and link-state routing protocols. EIGRP provides features such as rapid convergence, scalability, and support for multiple network protocols.… Read More »

How to Troubleshoot  and Verify NAT Configuration.

Network Address Translation (NAT) is a crucial networking technique used in routers and firewalls to manage the allocation of IP addresses in a network.Its primary purpose is to allow multiple devices within a private network to share a single public IP address for accessing resources on the internet. It’s a common networking method that allows multiple devices in… Read More »

Border Gateway Protocol Explained with Examples.

What Is Border Gateway Protocol? BGP is a complex, advanced distance routing protocol. It can best be described as Exterior Gateway Protocol (EGP). It’s been referred to in many quarters as the ‘big dog’ protocol of the internet. BGP exchanges routing information between Autonomous Systems (ASs). Unlike Interior routing protocols such as RIP, EIGRP, and OSPF that run inside a company’s network,… Read More »

DHCP Snooping Explained.

What Is DHCP Snooping? The Dynamic Host Configuration Protocol (DHCP) allocates IP addresses dynamically, it leases addresses to connected devices and the addresses can be reused when no longer needed. All connected Hosts and end devices that require IP addresses obtained through DHCP must communicate with a DHCP server across the LAN. DHCP snooping acts like a firewall… Read More »
