IPsec is a set of protocols and technologies designed to secure internet communication. It is also known as Internet protocol security. IPsec is useful in providing security and authentication to the data sent over the internet. IP packets when sent, do not have any added security to them, and an attacker can easily access the … Read more
Internet routing works on packet hopping from one router to another until it reaches the destination address. IP Packet contains no information about the route which it must follow to reach the destination. It just contains the destination IP Address. In this process, each router that receives the packet has to make an independent forwarding … Read more
The Cisco Virtual switching system is the technology introduced in CISCO catalyst 6500 series switches, which overcomes the drawback of EtherChannel and Spanning Tree protocol. It allows two catalyst switches to work as a single virtual switch. Before understanding how it works and its benefits, let us first understand the Cisco Three-Layer Hierarchical Model. What … Read more

Open Shortest Path First (OSPF) is a commonly used Internal gateway routing protocol for routing within an Autonomous System. OSPF’s capacity to optimize the routing table by separating the network into areas is one of its most important features. We have discussed OSPF, its backbone area, and standard areas in our previous blogs. Today, … Read more
Avoiding network loops in a network is of utmost importance. iBGP uses the split horizon rule to avoid loops. However, due to the Split horizon rule, all the iBGP neighbours must be in a full mesh topology. But why should the iBGP neighbours be in a full mesh topology? Split Horizon states that routers that … Read more
A prefix list is a set of IP Address prefixes that are grouped and can be denied or permitted to be advertised into the routing protocol according to our needs. Suppose there is a network topology with 5 routers and EIGRP is running on it. We need to filter some routes of R1 from R2 and … Read more
Before we dwell deep into multicast routing protocol, let us discuss the modes of transmission. Transmission of the packet can be done in three ways, namely- Unicast In the case of unicast, the packet is sent from one sender to one receiver, i.e., it is one-to-one communication. Broadcast In the case of broadcast, the message … Read more
