What are the advantages of using default routes?

They establish routes that will never go down. They keep routing tables small. They require a great deal of CPU power.

What is the use of default routing?

In computer networking, the default route is a configuration of the Internet Protocol (IP) that establishes a forwarding rule for packets when no specific address of a next-hop host is available from the routing table or other routing mechanisms.

What’s the difference between static and default routes?

Static Routing – This is the method by which an administrator manually adds routes to the routing table of a router. Default Routing – This is the method where all routers are configured to send all packets towards a single router.

What are the benefits of using dynamic routes?

Advantages of dynamic routing It is straightforward to configure. It adapts to network topology changes. It is suitable in a network where many routers are used. Configuring dynamic routing does not require detailed knowledge of the network.

How many default routes can you have?

No, it can’t have more than one active default gateway. Any operating system can have multiple default gateways configured (technically a route to the unspecified address, i.e. 0.0. 0.0 or :: ).

What are the advantages of dynamic routing protocols?

The chief advantages of dynamic routing over static routing are scalability and adaptability. A dynamically routed network can grow more quickly and larger, and is able to adapt to changes in the network topology brought about by this growth or by the failure of one or more network components.

What are the advantages and disadvantages of dynamic routing?

Table 3-3 Dynamic Routing Advantages and Disadvantages

Advantages	Disadvantages
Automatically adapts topology to reroute traffic if possible.	Route depends on the current topology.
	Requires additional resources such as CPU, memory, and link bandwidth.

Which route is preferred static or default?

Hence static routes are given more preference than any other route when configured on a router. Default Routes: The default routes are used when an IP packet does not find a route to its destination address from the routing table. Default route is a special case of static routing.

What are the advantages and disadvantages of static routes over the dynamic routes?

Table 3-2 Static Routing Advantages and Disadvantages

Advantages	Disadvantages
Very secure. No advertisements are sent, unlike with dynamic routing protocols.	Configuration complexity increases dramatically as the network grows. Managing the static configurations in large networks can become time consuming.
