Hello cisco community,
I have been recently asked to design a network. What I have for equipment is four 2960G's and one 1941 router.
One switch is a root switch and the other three will have end devices on them.
I have decided on three Vlans to go with: VLAN20 Data, VLAN30 ISCSI, and VLAN99 Management each with seperate trunk links and redundancy (see picture below)
I have a seperate trunks for each Vlan using the switchport trunk allowed. With exception to the Data Vlan.
My design has the Data Vlan as the native because it is going to be receiving untagged traffic from the external network.
I have set up intervlan routing on the 1941 via sub-interfaces to allow them to talk to eachother (or because of allowed they cannot?)
I have one port coming from my router to my switch via Ethernet cable which is my bridge out.
I have my external port doing a NAT translation for my inside addresses and a Default route set up ip route 0.0.0.0 0.0.0.0 gig0/0
I am using rapid-PVST to prevent loops and provide my zero downtime convergence when a link goes down.
As it stands right now I cannot talk out of my network or inside of my network.
You can see it is highly redundant and I do not want to change it. This network is going to be deployed but there will never be anybody physically there to manage it which is why I made it as redundant as humanly possible.
I am looking suggestions to help a first time designer make this complexity a little more simple.
