Hi I am redesigning a network for the please can someone clarify the following questions;
At the DC I have a:
2 x Distribution switches 4506-10G
2 x Core switches 6500 10G
2 x DMZ switches 4503
The Dis switch is where I connect the external connection to the Client site. Do I also configure all the Virtual vlan interfaces on the Dis switches with the routes to different networks? Or do I configure the vlans interfaces on the Core where all the blades are connected with the 10G uplinks
we have a L2 network. So my understanding is to have all the external client links connected to the DIS and create all the virtual vlans on the core. The DMZ is where we plu in the firewall interfaces segrated vlans but not the external web
Given this less-than-optimal topology, I sort of agree with Collin.
The 6504s are effectively acting as server farm distribution layer switches, the server blades being the access layer.
The 4506s are acting as aggregation switches for the different users/clients (by the way, makes me wonder why the clients arent firewalled, but I guess that is another discussion) who access the data center via L2 links. So, the L3 boundary should be the 4506s. This is where the user and client L3 SVI interfaces should be created and inter-vlan routing occuring.
So, as for the core, I would either get two more switches and have redundant L3 links between them and the server farm and user/client modules, with OSPF or EIGRP, leveraging ECMPs. Or, use redunandt L3 uplinks bteween the user aggregation and server farm switches and have the server farm switches act as a collapsed core.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
