OSPF Route Summarization

In large internetworks, hundreds, or even thousands, of network addresses can exist. It is often problematic for routers to maintain this volume of routes in their routing tables. Route summarization (also called route aggregation or supernetting) can reduce the number of routes that a router must maintain, because it is Read more…

Configuring EIGRP

Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used to share routes with other routers within the same autonomous system (AS number). Unlike other routing protocols EIGRP was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers. Furthermore EIGRP only sends Read more…

Configuring BGP

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator and is involved in making core routing Read more…

Configuring OSPF

Open Shortest Path First (OSPF) is interior gateway protocol (IGP) that makes use of a link state routing (LSR) algorithm. OSPF supports complex networks with multiple routers and may be structured, or subdivided, into routing areas to simplify administration and optimize traffic and resource utilization. Areas are defined as the backbone area, Read more…
