Redistribution between OSPF and EIGRP  

route redistribution between ospf and eigrp

In a network, there is a possibility that it is running on both OSPF and EIGRP and the route of OSPF cannot be advertised to EIGRP by itself. Similarly, routes of EIGRP cannot be advertised to OSPF by itself.    We can make use of Redistribution to advertise routes between each other.  Route Redistribution is a … Read more

Do they share the routes between them? What is Route Redistribution? Route Redistribution is a process that helps to exchange routing information from one routing protocol to another. … Read more

What is Route Summarization?: Explained

route summarization

Route summarization, also known as route aggregation or supernetting, is a technique used in networking to reduce the number of routes in a routing table by combining multiple smaller subnets into a single larger network address. Route Summarization helps simplify and optimize routing in a network. It can be used in routing protocols like OSPF, … Read more

HSRP Configuration: Explained

hsrp configuration

HSRP is a protocol that helps to achieve the failover. With the help of HSRP, we can configure active and standby routers and that goal is achieved with the help of a virtual IP.
