Configuring Network RoutingBroadly network routing can be configured in two ways1. Static Routing 2. Dynamic Routing
Static Routing: Static routing is usually configured for small networks which has relatively less number of routes. Sometimes static routing is also used in larger networks but as a small part of dynamic routing infrastructure. When used in larger networks, static routing directs traffic to another network that is controlled by another party.
Dynamic RoutingDynamic routing is used for larger networks and it automatically changes with ongoing changes in network topology.
It enables reachability to all potential destinations that exist in the network.
Eliminates the manual configuration requirements and they are built capable enough to handle the multiple complex network topologies simultaneously.
Efficiently deals with network outages - without need of additional network administrative resources.
Types of Dynamic RoutingOnce dynamic routing method is opted, network engineers will focus on selecting the types of dynamic routing protocols.There are two main categories of dynamic routing protocols1. Exterior Gateway Protocols (EGPs) 2. Interior Gateway Protocols (EGPs) Exterior Gateway Protocol EGP is a routing protocol that enables data exchanging
between two neighboring gateway hosts which exist in a network of autonomous Systems.
It connects multiple network domains (service provider network or an organization network) and this protocol is exterior to the network domains.
Typical application areas includes private organizations, research institutes, government agencies and universities.
Interior Gateway Protocol IGP is a routing protocol that enables exchanging
routing information between routers within in an autonomous system (one routing domain).
IGP is used to route the internet communications within a local area network LAN( within office environment).
These dynamic protocols monitor the data movement from one end of the system to other end within a network or set of networks in single autonomous system.
IGP efficiently deals with network limitations and supports routing metrics such as load, delay, reliability and bandwidth.
Types of Dynamic Routing (Continued..)
Benefits of Dynamic Routing Independent of network size. Fits best to all network topologies (multiple routers). Enhances scalability and adaptability in the network. Dynamically routed networks quickly adapt to the
changes which includes growth and or component failures in network topology.
Enables effective communication between routers in the network, routers are better informed about the network topology with dynamic routing protocols.
Empowers networks to function effectively even when partial network failure or configuration changes occur.
More complexities in initial implementation. Less secure as it involves multicast and broadcast
routing updates. Enterprises need to procure additional resources which
includes memory, CPU and link bandwidth. Demands additional configuration settings such as
routing protocol authentication and passive interfaces in order to ensure enhanced security.
