Subnetting Project. You are a consultant for being brought

Customer Question

Subnetting Project. You are a consultant for being brought in by XUC to assist with a merger with another company. Background: XUC is has the WAN links in place to the new locations in the Houston Region. XUMUC currently has 2 other Regions San Francisco and Denver. Originally, XUMUC was only in one region (San Francisco). The previous consultant did a poor job with the integration resulting in a poor IP address scheme as a result routing tables at the summarization points and at the San Francisco Campus are very large. In addition, no VLAN structure was developed to isolate broadcast traffic. There are 4 main departments in XUMC: sales, finance, human resources, and research and development. Also, there has been some concern that the WAN transport was not able to accommodate the network traffic. Finally, all addresses in the network are statically assigned resulting in high administration overhead when changes are needed XUMC would like this changed to lower administrative overhead.

David, Wow, thank you. However, I jumped the gun a bit. Our question is slightly different. (less individs in SF). Not a problem to re-issue funds again. You did an excellent job. I just ran out of time and needed the breakdown this time around. See below for question. Thanks. Please let me know what I need to do next.

My initial question had some inacurrate information. David did an excellent job, btw! Here is the correct question.

Hello,

I will modify the document and repost it shortly.

Thanks.

Hello,

Please review the revised document at the link below:

Note that each region has more IP addresses allocated than hosts present in the location. The reason for this is to facilitate the route summarization requirement using the third octet. The additional IP addresses also provide for growth within each region.

Thanks,

tks Dave. I'm good with MS, jes took the run on CCNA routers information. Embarrasing to ask for help, yes. I'll review all. Again, thank you. -btw- how do you get a $$ tip? v/r, Marc


 

Expert:  David L. replied 2 years ago.
Ok, just let me know if you have more questions about the report.

Regarding the tip, once you select a positive rating there is a bonus that you can enter that is essentially a tip.

Thanks,

David, I understand the IP breakout and summarization scheme. Thanks. however, this class is more routers. I'm not sure what the IP's would be for the site routers utilizing /30 while part of the subnet? You provided:


San Francisco 172.16.0.0 – 172.16.7.255/27 64 30 1920


Denver 172.16.8.0 – 172.16.11.255/27 32 30 960


Houston 172.16.12.0 – 172.16.13.255/27 16 30 480


 


Then, in order to decrease the size of the network routing tables, the following route summarization will be used with OSPF:


Route to San Francisco 172.16.0.0 255.255.192.0


Route to Denver 172.16.16.8.0 255.255.224.0


Route to Houston 172.16.12.0 255.255.240.0


 


The subnet range for each site location includes an overage of IP addresses for immediate and future network expansion. (Cisco, 2012) All remote offices will be assigned subnets from within the subnet and IP address ranges assigned to the major campus and region with which they are associated and to which they connect.


idea? tks.

Expert:  David L. replied 2 years ago.
Hello,

There is supposed to be a 172.16.14.0 - 255 range reserved for WAN administration. So the IP address ranges should be:

Houston to San Fran - 172.16.14.0-3/30, using 172.16.14.1 and 2 for router WAN interfaces.

Denver to San Fran - 172.16.14.4-7/30, using 172.16.14.5 and 6 for router WAN interfaces.

Denver Remote Office 1 - 172.16.14.8-11/30, using 172.16.14.9 and 10 for router WAN interfaces.

Denver Remote Office 2 - 172.16.14.12-15/30, using 172.16.14.13 and 14 for router WAN interfaces.

Houston Remote Office 1 - 172.16.14.16-19/30, using 172.16.14.17 and 18 for router WAN interfaces.

Please let me know if that makes sense or if you need further information.

Thanks.

David.
Customer: replied 2 years ago.

yes, thank you. One other ques and I'll leave you alone. -Summarization routes- you stated:


(1) Route to San Francisco 172.16.0.0 255.255.192.0


(2) Route to Denver 172.16.16.8.0 255.255.224.0


(3) Route to Houston 172.16.12.0 255.255.240.0


 


Ques: Route to SF is the route summarization I would place at the SF router? Likewise, for route to Denver (placed at Denver router. And then, route to Houston, placed at the Houston router summarization point? Thanks Dave for the assist.
