3 tier network guidance

[AvidPontoon1]

With my job I am studying for the CCNA and have got onto all routing protocols.

I have made several collapsed core networks with the core and distribution on one tier with vlan ip's and stp root bridges set. This was with 4 vlans. The network also used HSRP for gateway redundancy and EIGRP to allow the other vlans to access the internet and other vlan traffic (intervlan routing).

Now I would like to make a hierarchical 3 tier network in packet tracer to get it started. I plan to have 2 core switches with a port channel of 4 ports for a link aggregation. Then the distribution level with 2 switches. These will have a connection from both core switches each to create a mesh. Then for the access layer. I plan to have 4 layer 2 switches. These too will have a connection from each distribution switch each to create another mesh.

With the design out of the way I would like help with the implementation. Where do I have the router so EIGRP will work on all vlans? And how do I setup EIGRP? Will the STP root bridges be on the core or distribution layer? And will HSRP be on the core or distribution?

I tried to make a network like this a few hours ago and got most of my spanning tree working on the distribution layer with core being the vlan 1 root bridge and then vlans 10 20 30 and 40 split between 2 distribution switches but EIGRP didn't work and did not pick up any neighbours so I was only able to access the internet on vlan 1 and no other vlans could access it. What did I do wrong and how can I get a working 3 tier network to show off my skill?

Any help is greatly appreciated

Hi @AvidPontoon1

 Why do you believe you need EIGRP first off?

 Can you share the packet tracer file?

I used a guide for the first network so thought I ought to use it again, what would I use instead of EIGRP?

And unfortunately I deleted the packet teacher file out of rage. I may be able to recover it

OSPF is way more common. But, let take a look in your lab and I'll give an opinion.

Here is  the file, its a bit of a mess!

Actually, everything looks good for me. As soon as I enabled the EIGRP on core 1 and advertised all network, I could see them on the router coming via EIGRP:

IntRouter#sh ip route

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

* - candidate default, U - per-user static route, o - ODR

P - periodic downloaded static route

Gateway of last resort is not set

1.0.0.0/32 is subnetted, 1 subnets

C 1.1.1.1/32 is directly connected, Loopback0

192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks

C 192.168.1.0/24 is directly connected, GigabitEthernet0/0/0

L 192.168.1.1/32 is directly connected, GigabitEthernet0/0/0

D 192.168.100.0/24 [90/25625856] via 192.168.1.251, 00:00:21, GigabitEthernet0/0/0

Wow!

Could you possibly send the file back or tell me the commands or the configurations on the routers and switches as when I advertised the routes nothing happened?

Thankyou so much!
