Quizz for the Statics in our Routes

Qn. Why are routes manually configured (Static Routing) between two networking devices ?

Ans : To provide,

• Ease of understanding

  and

  better solutions

• Precise paths

  and

  improved network

• Improved Security

  and

  Resource Efficiency

• Better solution than dynamic routing

  and

  waste time

How should static routes be understood ?

• Path to get to Exit interface of the router.

• Path between routers.

• Path to reach networks beyond or to next hop router.

• Path from one router to another to reach a certain destination.

Does static route automatically change, when new networks are added ?

• Yes, they change with respect to new networks added.

• No, they do not change with respect to new networks added.

What is, A computer network with no knowledge of other networks, that will send much or all of its non-local traffic out via a single of a default route to non-local destinations.

Hint : Isolated Network

What is the sequence for static routing ? (With respect to Next Hop Router)

• Connecting Interface IP then Exit Interface IP.

• Exit Interface Network IP then Connecting Interface IP.

• Connecting Interface ID then Exit Interface IP.

• Exit Interface Network ID then Connecting Interface IP.

Answer explanation

ip route {destination-ip-prefix/exit-net-ID + <net mask> | connecting-ip-int/Forwarding-ip-int}

While configuring static route for R1 to R2,

Circle the destination Interface/exit interface for the next hop route with Green

Circle the forwarding interface/connecting interface for the next hop route with Red

Answer explanation

R2 - G0/1 - Green

R2 - G0/0 - Red

The benefits of Static routing are:

1. Improved Security

2. Resource Efficiency

This is because =

• 1. Easy to safe guard

  2. No need to re-configure

• 1. Routes are permanent

  2. No need for update mechanisms

• 1. Routing Information is not advertised

  2. Additional Update algorithm not required

• 1. Routing Information is safe guarded

  2. Additional protocols not required

What is the command to check the routing table ?

For the static route for R1 between R2 and R3, what are the connecting /forwarding router interface ?

• 172.22.1.158

  and

  172.31.157.97

• 172.22.1.160

  and

  172.31.157.0

• 172.31.157.65

  and

  172.31.157.96

• 172.0.0, 172.22.0.0

  and

  172.31.0.0

Type out the main command to input static route in ipv4.
