2. Configuring Network Routing
Broadly network routing can be configured in two ways
1. 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.

3. 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 simultaneously.
 Efficiently deals with network outages - without need of additional
network administrative resources.

4. 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 protocols
1. 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.

5. 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.

6. 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.

7.  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.
