Hello everyone -
I have a design question that involves a Cisco ASA firewalls (2 actually, one of them is for failover), a stack of 3750 switches and a Cisco 3845 router. I am a little confused about how the equipment should be connected for optimal routing and switching at our data center.
Here's the scenario. We will have 3 VLAN's hosting different kinds of servers. These servers need to be accessed by all sites that are connected to our MPLS cloud. The 3845 router too will be connected to the MPLS cloud from our data center. The ASA's (also at the DC) will be connected to an Internet router for Internet connectivity.
So here are my questions:
1. how should the 3845 router be configured so that it routes traffic to different sites, but also provides access to the internet from servers in all different vlan's?
2. would i need to create a trunk port on each switch in the stack or just 1 trunk port for the stack should be enough?
3. would I need a router interface and an ASA interface on each vlan?
I am a little confused about this thing...So any help would be greatly appreciated!!
