Hello,
I am new user in the Cisco world but have had several months of school training, however I still feel baffled by all the commands, terminology etc that comes with being introduced to Cisco.
For a school project I am building a 3-tiered cisco network with the following structure:
1 ASA (5505) (or two ASA if I can get a license to failover)
2 Core switches (3560)
4 Dist switches (also 3560)
4 Access switches (2960) (I could have 4 in each distribution zone but for the demonstration it is not neccessary)
As link between the Acc switches and the dist switches I think I will use trunked L2 etherchannels. There will be maximum two VLANs on each switch for clients/servers.
The right side will be for client access (4 departments, 1 per vlan).
The left side for server access (probably only need 2 vlans for the server side, one for DMZ webserver and one for internal servers).
DHCP shall be managed by domain controllers that I setup later on, so no dhcp pool is supposed to be required on the switches.
I will make L3 etherchannels between the distribution/core switches.
Is above mentioned things valid/good or are there much easier/better approaches?
Later there should be a routing protocol implemented in the core/dist - I'm thinking OSPF or EIGRP.
My problem is that I am starting to run out of time because I experience trouble getting the basics right.
I need help with good literature on IP Addressing scheme.. I'm thinking of just making it 10.10.x.0/24 for the host networks so I can summarize them into 10.10.0.0/19 on the distribution. But where do I start? What IPs should I choose for the switches etc ?
SSH
I can get SSH to work on the access switches but I cannot figure out how to SSH from the acc switch to the distribution switches and further on.
I'd like to just be able to SSH around all the switches and then implement the features in a one-by-one fashion.
I need help with setting this up and the literature I have found is so comprehensive and confusing..
Subnets
When I have multiple subnets on one switch, what should I then choose as default gateways, management IPs and so on?

Any thoughts and help will be greatly appreciated..
