Implementing Static Routing

• Static routing involves manual configuration of routes in a router's routing table.
• There are two ways to discover remote networks:
  • Manually: introducing static routes into the routing table.
  • Dynamically: using a dynamic routing protocol.

Advantages and Disadvantages of Static Routing

• Advantages:
  • Static routes are not announced to the network, increasing security.
  • They consume less bandwidth than dynamic routing protocols.
  • No CPU cycles are used to calculate and communicate routes.
  • The route used to send data is known.
• Disadvantages:
  • Initial configuration and maintenance are time-consuming.
  • Configuration is prone to errors, especially in large networks.
  • The administrator must maintain changing route information.
  • It does not adapt well to growing networks; maintenance becomes increasingly complicated.

When to Use Static Routes

• Three main uses of static routing:
  • Facilitating maintenance of the routing table in small networks that are not expected to grow significantly.
  • Providing routing to internal networks and from them.
  • Using a single default route to represent a route to any destination that does not have a more specific match in the routing table.

Types of Static Routes

• Four types of static routes:
  • Standard static route
  • Default static route
  • Summary static route
  • Floating static route
• Each type has its own use cases and configuration options.

Configuring Static Routes

• The command "ip route" is used to configure static routes.
• Options for the next hop:
  • Specifying the IP address of the next hop.
  • Specifying the outgoing interface.
  • Specifying both the IP address and outgoing interface.
• The route type determines the next hop specification.

Verifying Static Routes

• Useful commands for verifying static routes:
  • show ip route
  • show ip route static
  • show ip route [network]
  • ping
  • traceroute

Configuring Default Static Routes

• A default static route is a static route that matches all packets.
• It is used to represent a route to any destination that does not have a more specific match in the routing table.
• Configuring a default static route:
  • Using the command "ip route 0.0.0.0 0.0.0.0 [next-hop-IP]"

Classful Addressing

• Classful addressing uses a fixed-length subnet mask (FLSM) to determine the network portion of an IP address.
• The main problem with classful addressing is the waste of IP addresses.
• The introduction of CIDR (Classless Inter-Domain Routing) and VLSM (Variable Length Subnet Masking) helped to alleviate this problem.

CIDR and VLSM

• CIDR allows for the summarization of multiple routes into a single route.
• VLSM allows for the use of different subnet masks for each subnet.
• CIDR and VLSM work together to enable efficient routing and reduce the size of routing tables.

Configuring Summary Static Routes

• The process of summarizing routes:
  • Enumerate the networks in binary format.
  • Count the number of coincident bits from the left to determine the prefix length.
  • Copy the coincident bits and then add zeros to determine the summarized network address.
• The command "ip route" is used to configure summary static routes.

Configuring Floating Static Routes

• A floating static route is a static route that is used as a backup route.
• It is used to provide a backup route in case the primary route fails.
• Configuring a floating static route:
  • Specifying a higher administrative distance than the primary route.
  • Verifying the route using the command "show ip route".### Static Routing
• A static route is only added to the routing table if the next hop's IP address can be resolved through an output interface.

Conditions for Adding Static Routes

• A static route is not added to the routing table if the output interface used to forward the packet is not in the table, regardless of whether the static route is configured with a next hop IP address or an output interface.

Summarized Routes

• Multiple static routes can be configured as a single summarized route.
• The final summarized route is a default route configured with a network address of 0.0.0.0 and a subnet mask of 0.0.0.0.

Default Route

• If there is no more specific match in the routing table, the default route is used to forward the packet to another router.

Floating Static Routes

• A floating static route can be configured to back up a primary link by manipulating its administrative value.
