I'm implementing a multi site network and intend to use OSPF to do it. The links between each site at either 100mbps fibre or 1gbps
My question is, is this better to be done with switches (3560x with IP Base) or routers (2921)? What are the main pros/cons of each? I understand that the 2921 can do far more with securtiy between sites and probably has more advanced QoS(?)
Switches will provide a faster throughput performance but it lacks a lot of software features such as NAT, Advanced QoS, NetFlow, among others.
The router will provide all software features but lower performance compared to a switch.
