Configuring Network Routing
  • Broadly network routing can be configured in two
  • Static Routing
  • 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 Routing
  • Dynamic 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
  • Efficiently deals with network outages - without
    need of additional network administrative

Types of Dynamic Routing
  • Once 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
  • Exterior Gateway Protocols (EGPs)
  • 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.

Types of Dynamic Routing (Continued..)
  • 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
  • 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
  • IGP efficiently deals with network limitations
    and supports routing metrics such as load, delay,
    reliability and bandwidth.

Benefits of Dynamic Routing
  • Independent of network size.
  • Fits best to all network topologies (multiple
  • Enhances scalability and adaptability in the
  • 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
  • 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.
