EIGRP stands for Enhanced Interior Gateway Routing Protocol which is just like the name implies, an enhanced version of the legacy IGRP. It is considered as an “Advanced Distance Vector Protocol” which uses 5 different type of packets to exchange information: -Hello: Hello packets are used to discover EIGRP neighbors. -Update: Updates are mainly used for [ Read More ]
DMVPN stands for Dynamic Multipoint VPN and it is a dynamic tunneling form of a virtual private network (VPN). It represents an effective solution for dynamic secure overlay networks by forming a partial dynamic mesh network. Okay ! That’s a lot of ‘dynamic” but let’s move on. In this post, I will show you the [ Read More ]
In this section, we will discuss securing your data while transmitting through a GRE tunnel. If you are unfamiliar with GRE tunnels, please take the time to read this post here first. We will use the same topology as the one used in the GRE post. We will just add encryption on top. It is [ Read More ]
GRE stands for Generic Routing Encapsulation. As the name implies, it is a mechanism or tunneling protocol that permits the encapsulation of many different IP protocols inside an arbitrary transport protocol. It can be used for a number of things such as: *Provide multi-protocol local networks over a single-protocol backbone *Provide workarounds for limited hop counts networks. A [ Read More ]
In this post, we will talk about MPLS (Multiprotocol Label Switching) which is an open standard base protocol capable of transporting different type of either L2 or L3 payloads. We will look at facts in terms of the origin of the protocol, some of the different design options we have available today and how to [ Read More ]
Etherchannel which is also known as Link Aggregation and it is a protocol that allows grouping or bundling of multiple physical Ethernet links into a single logical one. Its main purpose is to provide fault-tolerant high-speed links between network devices and also servers. In today’s network, bottlenecks are fairly common and sometimes you may be [ Read More ]
VTP stands for “VLAN Trunking Protocol”. It is a Cisco-proprietary protocol designed to reduce administrative overhead in a switched network. Basically, when a new vlan is configured on the VTP server, it is then propagated throughout the switches. This behavior eradicates the need to configure the same vlan on each switch. You can imagine how [ Read More ]
In this post, we will talk about Trunk Links and the purpose to implement them in your environment. We will be using the following topology… First, let’s talk about the meaning Trunk Link and its purpose. In layman’s terms, a trunk link is nothing but a regular link with the ability to pass and [ Read More ]
STP (Spanning-Tree Protocol) is one of those protocol that’ll run in the background with minimal management overhead providing there are no topology changes. STP functions is to primarily prevent bridge loops in a single broadcast domain. Given its capabilities, it is also used in network design in terms of redundant links as it provides dynamic backup [ Read More ]
In this switching section, I will show you the basics of configuring VLANs on Cisco Catalyst switches as well as verification steps you can perform to ensure your configuration is accurate. The following is the diagram we will use for this purpose: As you can see above, RouteLeak-RT01 is connected to RouteLeak-RT02 via RouteLeak-SW01. First let’s [ Read More ]
