Multicast addresses are the IP addresses that refer to a group of hosts present in the same or on different networks. We refer to this group of hosts as a multicast group. Multicast addresses are ways to distribute a common data stream or service to the hosts in multicast addresses. Multicast Addresses in IPv4 Addressing in IPv4 can be classified into two kinds of addressing … [Read more...] about Multicast Addresses

Open shortest path first is a routing protocol that determines the shortest distance between two routers in an autonomous system. The OSPF protocol is developed on the basis of link-state routing that we discussed in our previous content. In this section, we will discuss the working of OSPF. We will also discuss the types of links in OSPF and also the types of OSPF … [Read more...] about Open Shortest Path First

Link state routing is an interior protocol that updates the routers inside the autonomous system i.e it is an intradomain protocol. The link-state routing was introduced to overcome the shortcomings of the distance vector routing protocol. The reason behind the replacement of distance vector routing protocol was it would take too long to propagate the information about the … [Read more...] about Link State Routing

Packet forwarding is the process of directing the packet towards its destination. As we know that Internet is a combination of several networks. A packet may belong to the same network as of source host or it may be for the destination host in a different network. So, a packet from a source host may have to travel many networks before reaching the destination. Packet … [Read more...] about Packet Forwarding

Routing information protocol (RIP) is a routing protocol that lets routers of an autonomous system inform each other about the changes inside the network. It is an intra-domain routing protocol as it updates the routing tables of routers inside an autonomous system. Routing specifies all those protocols that define the route of packets from source to destination across multiple … [Read more...] about Routing Information Protocol
