Network Design Advice

[captnops]

My network is pretty simple, but I would like to build more redundancy into the current design.

Hardware:
Cisco 2811 Router w/ 4 T1 cards
Cisco 3650 POE Switch
Linksys srw224 POE switches (3)

Circuits:
PTP T1 to client terminating at Cisco 1720 (my closet)
T1-Vendor 1
T1 Vendor 2
T1 Vendor 2 (geo diverse pull)
768K Vendor2
DSL Vendor 3

I am currently terminating all T1's to the cisco 2811 router. I have a ADSL card in the router, but I am not currently terminating the DSL circuit there in case of router failure.

A single FE port on the router attaches to the linksys switches which are tied by the Gig ports. The 3650 has not been put into the rack yet.

I need to make due with the hardware I currently have and would like to remake this mess with as much redundancy as possible.

Environment:

Data and Voip

I believe that I need to create VLANS to segment the VOIP traffic from the data. Additionally, the VOIP devices are on a stick to the workstations (ie they belong to the same physical subnet) so I would need to segment the voice traffic somehow.

Your help would be greatly appreciated.

It's recommended to create a Data VLAN and Voice VLAN. Since you have the 3560 Switch with PoE capabilities, it shouldn't be a problem and you can do the routing (creating SVI interfaces) on the 3560 as well. Make sure you enable AutoQoS for all of our ports enabled for Data+Voice ports to allow proper hardware queuing and congestion avoidance for your voice traffic.
