I need Help with the topology of an ISP company in cisco Packet tarcer

[sochetrasot]

Hello and thank you for my time, the thing i need help with is for my CCNA 2 project which is about

Objective:

The objective of this assignment is to design and implement the infrastructure of an Internet Service Provider (ISP) while incorporating various modules from CCNA 2, specifically focusing on Switching, Routing, and Wireless Essentials. Students will gain practical experience in configuring VLANs, STP, EtherChannel, DHCP, HSRP, Dynamic Routing Protocol (RIP), Wireless, and other relevant technologies to provide internet services to clients (Home Users, Banks, Enterprise, etc.)

Requirements:

• ISP must allocate and provide the IP addresses to different clients.
• Students should insert a server by connecting from ISP to the server that contains the website.
• Students should use Routing Information Protocol (RIP).
• The clients in different VLANs must access the ISPs in different ways by using HSRP to connect the core router of ISP.

NOTE: “Please try to implement the modules from CCNA 2 as much as you can, as your score will be based on the modules that you will be applying in your assignment”


from that requirement my concept is to build an ISP network to provide to rural areas where they have a school, internet shop and like home users and provide them with web services but after thinking i just can not think of a topology that represent that in cisco packet tracer so can anyone help?

Thank you.

Couldn't you just do a star/hub and spoke topology, and designate the hub router as the "ISP"? Something like this.

[sochetrasot]

But if i use the hub and spoke topology what about the requirement to connect a server to the isp ?

[matthew2587]

1.  You can build a more in detail network than the one above for the "ISP" portion, and allow it to include a server.
2. The requirements say "Connecting from ISP to the server", so you could give the server its own network, and route traffic to it through the ISP.

Do you think either of those would work for you?

[sochetrasot]

Yea i think that would work thank you for your suggestion

Certainly, I can help you with the topology of an ISP (Internet Service Provider) company in Cisco Packet Tracer. Creating a comprehensive ISP topology involves multiple components such as routers, switches, and servers. Below is a basic example of an ISP topology in Cisco Packet Tracer:

plaintextCopy code
ISP +----------+ | | +------+ Internet +------+ | | Cloud | | | +----------+ | | | | | | | +----+----+ +----+----+ | | | | | Router 1| | Router 2| | | | | +----+----+ +----+----+ | | +---+----+ +---+----+ | | | | |Switch 1| |Switch 2| | | | | +---+----+ +---+----+ | | +----+----+ +----+----+ | | | | | PC1 | | PC2 | | | | | +---------+ +---------+
Explanation:

ISP (Internet Service Provider):

Represents the external connection to the Internet.
Internet Cloud:

Symbolizes the global Internet infrastructure.
Routers (Router 1 and Router 2):

Connect the internal network to the ISP and manage traffic between the internal network and the Internet.
Switches (Switch 1 and Switch 2):

Provide local network connectivity, connecting end-user devices (PC1 and PC2) to the routers.
End-user Devices (PC1 and PC2):

Represent the computers or devices used by customers or employees.
This is a basic representation, and you can customize it based on your specific requirements. In a real ISP environment, you might have multiple routers, switches, and additional infrastructure components to handle the complexity of providing internet services to a large number of customers.

If you have specific requirements or questions about certain aspects of the ISP topology, feel free to provide more details so that I can offer more targeted assistance.

What about this this kind of topology

[matthew2587]

I think that topology looks good and will meet the requirements.

[sochetrasot]

so i am going to use the router rip v2 routing protocol for my 3 router and do HSRP on 2 left and right outer but i dont know what i should configure on my layer 3 switch so that it can reach the other network like my school router or the router to cell tower?

[matthew2587]

I am assuming you mean the routers using rip v2 are the ones that are connected with serial?

(I am not very familiar with rip configs) For the layer 3 switch, could you just use rip on them as well so there are dynamically learned routes for all the networks? Or you can just use static routes for simplicity.

• The clients in different VLANs must access the ISPs in different ways by using HSRP to connect the core router of ISP.

This requirement makes me think that you need another router next to router 4, and then configure both of them with hsrp.

[sochetrasot]

so i should just user rip on them as well and we let them leraned the network for all the 3 customer and the the router connect to serial as well on my l3 switch ?
so add an extra router to all of my customer is what you are saying ?

[matthew2587]

I would say just use rip on the multilayer switches, and routers 0,1,2. But, you will probably still need to add some static routes for full connectivity.

Yes, add an extra router for hsrp, like this, to meet the requirements of clients accessing the ISP in different ways with HSRP. Note that these configurations will need to be made on subinterfaces because you are using router-on-a-stick. I believe, you can change the priorities (for hsrp) on the subinterfaces, so different vlans will go to different routers.

You might also change those routers to multilayer switches, it might be easier that way.

[sochetrasot]

But do u know how to configure the left router and right router with HSRP to use the virtual  router IP so the 2 l3 can use that gateaway or i do not need it ?
