For large-scale implementations, the Enhanced Interior Gateway Routing Protocol (EIGRP) or Border Gateway Protocol (BGP) are more suitable. EIGRP is not restricted by the topology limitations of a link state protocol and is easier to deploy and scale in a DMVPN topology. BGP can scale to many...

BGP: The Border Gateway Protocol (BGP) is an application layer protocol networks use to broadcast which IP addresses they control. This information allows routers to decide which networks data packets should pass through on the way to their destinations. EIGRP: The Enhanced Interior Gateway Routing...
The focus? A central concept known as ‘routing.’ Often encountered by IT professionals on a daily basis, routing proves fundamental to the functionality of the internet. In this blog post, we will explore what routing is, how it works, its protocols, and how it impacts the digital world...
MPLS (Multi Protocol Label Switching) is a mechanism that switches traffic based on labels instead of routing traffic. Check course overview.
What is a network protocol? A network protocol is a set of established rules that specify how to format, send and receive data so that computer network endpoints, including computers, servers, routers and virtual machines, can communicate despite differences in their underlying infrastructures, design...
(When a packet goes from one network to another, this is known as a "hop.") Other interior routing protocols include EIGRP (the Enhanced Interior Gateway Routing Protocol, mainly for use with Cisco routers) and IS-IS (Intermediate System to Intermediate System). What is a router? A router...
When the other end receive this BFD message, the state filed is changed as UP. How BFD Works? Bidirectional Forwarding Detection mechanism uses packets to inform both ends that the protocol is configured. With these packets, it provides basic connectivity and the parameter negotiation. The main ...
Enhanced Interior Gateway Routing Protocol.EIGRPevolved from IGRP. If a router can't find a route to a destination in one of these tables, it queries nearby routers, which then query routers closer to them until a route is found. When a routing table entry changes in one of the routers,...
