Questions and Answers

What is the primary function of a default static route?

  • To dynamically adjust routes based on network traffic.
  • To connect all routers in a network.
  • To provide multiple specific routes for each destination.
  • To serve as a Gateway of Last Resort when no other routes match. (correct)
  • In which scenario is a default static route often utilized?

  • To manage bandwidth on dynamic routes.
  • When connecting a company’s edge router to the ISP network. (correct)
  • When there are multiple routers but only one exit interface.
  • In a fully meshed routing topology.
  • How can multiple static routes be summarized into a single static route?

  • If the networks are non-contiguous and vary in address.
  • By using separate exit interfaces for each route.
  • When destination networks are contiguous and share the same exit interface. (correct)
  • If the AD of all routes is identical.

    Study Notes

    Routing Basics

    • Routing is essential for transmitting data across networks from source to destination.
    • Routers manage the transfer of data packets between different networks.
    • Routers can learn about remote networks through dynamic routing protocols or static routes.

    Static Routing

    • Static routes require less processing overhead, making them efficient for small networks.
    • They do not need dynamic protocols and are manually added to the route table.
    • Commonly used in small organizations; larger networks may use a mix of static and dynamic routes.
    • Advantages include improved security (not advertised) and reduced bandwidth usage.
    • Disadvantages involve time-consuming setup, increased error risk in large networks, and difficulties in maintaining route changes.

    Dynamic vs Static Routing

    • Static routes are practical for small networks with a single path to an external network.
    • Dynamic routing protocols are complementary to static routes, allowing for multiple paths.
    • Administrative distance (AD) denotes route source preference; static routes have an AD of 1, making them preferred over dynamic routes.

    Use Cases for Static Routing

    • Ideal for maintaining routing tables in non-expanding small networks.
    • Effective in connecting stub networks, which have a single route to a collection of networks.
    • Utilized in configuring default routes for unlisted destination networks.

    Stub Networks

    • Stub networks refer to networks accessed through a single route.
    • Static routes can connect routers directly to stub networks, ensuring simple traffic management.

    Applications of Static Routes

    • Connect to specific networks or stub routers.
    • Summarize several routes into one static route to simplify routing tables.
    • Establish backup routes in case of primary route failures.

    Types of Static Routes

    • Standard Static Route: Directly connect to specific remote networks; applicable for both IPv4 and IPv6.
    • Default Static Route: Serves as a catch-all route for packets with no specific match; defined as 0.0.0.0/0.
    • Summary Static Route: Combines multiple contiguous networks into a single route, applicable if they share an exit interface.
    • Floating Static Route: Acts as a backup route; utilized when the primary static or dynamic route becomes unavailable, configured with a higher AD.
