Help on computer networking assignment?

Question

I have been given a network assignment to do, it is at my first year of university so I don't think it should be that complex. The IP address I have veen given is 172.29.0.0 /16. I need to assign subnets using VLSM.

In the case study it says this "At the location (Headquarters), the serial 0/2 is the default route for the network and will need configuring as such as that serial 0/2 is connected to the ISP. The IP address for this serial 0/2 interface is fixed as 145.45.5.100.

Can someone explain to me what is this serial 0/2 interface is and what exactly needs configuring as I am confused why I have been given 2 IP addresses (I know the first one is for the hosts and devices within the network) but how does the ISP address fit into this?

Thank you so much in advance.

Answer 1

Your default route is the route that all the traffic takes when there is no specific route defined in the routing table.

i.e. With a Cisco router you may enter the command - route 0.0.0.0 0.0.0.0 serial 0/2

When traffic enters your router, the router will check if there already a route for the destination IP. If there is no route present, the router will forward it to the serial 0/2 interface (to the ISP).

IP addresses are created from 4 8 bit octets. For ten computers you may choose ten ip addresses. so which you may use the final octet that's certainly those 8 bits (11111111 if became on or 00000000 if no longer became on). They bit positions characterize 128,sixty 4,32,sixteen,8,4,2,a million. So for ten computers you may desire to recognize sixteen is the variety extra suitable than ten plus you may desire to throw out 2 IP addresses for the community handle and broadcast handle. you often choose 2 extra IPs than your problem demands subsequently the formula 2N-2. in view so you might use the bit place that holds the sixteen your subnet may be 192.168.a million.0-192.168.a million.15 with the .0 & .15 being unusable for community and broadcast addressing. you'll be able to additionally use the 2d subnet which starts off with sixteen (192.168.a million.sixteen-192.168.a million.31). the different solutions might artwork yet are patently responded via amateurs who have not any actual worldwide community layout skills. study VLSM, CiDR, community math and you will understand.

Hi

i don't know your answer, but it's better to re-ask your question and change the title, it's good to write what language your assignment is in.

Is this your whole assignment's question? is there any other part that might help others to understand your assignment better?

you can add a short part of your assignment in the title instead of "help on computer networking assignment"

i hope these tips will help you find your answer sooner :D

Good Luck
