Netgear routing versus Cisco routing
Currently an organization i work for is looking at changing their network topology. They have a netgear fvx538 router as their core routing equipment and it also functions as the firewall. we are proposing using the cisco 3945 as the core router an asa 5510 as the firewall, the distribution switch would be the 3750 switch and the access layer switches can still be the netgear gsm 7328s since the switches are already on the network and to reduce the cost of buying all new 2960 switchws for the 7 floors. Are there any flaws to this topology or improvements or unforeseeable issues?

Answer Wiki:
First thoughts: You seem to be removing the Netgear Router altogether - Ifit still works as a router and/or firewall, why not keep it either in production, or as a back-up?
The proposed equipment is ok, just a few points to make it easier:
- Mirror the Internal IP address settings of the Netgear on the Cisco Router: All devices / DHCP scopes probably have it as a gateway, so use it
- Ensure that the ASA supports the same types of VPN connections (if any) that the Netgear does. Possibly replicate user settings from one device to the next
- Keep VLANs / Subnets, IP routing and functions as similar as possible, and it sounds like a fairly painless transition...
