Are you looking to , or are you putting together a virtual lab for study?
Physical home labs remain highly popular for studying networking fundamentals. Flashing a physical Cisco 2811 or 2821 router with IOS 15.2 provides a low-cost method to study modern syntax (like IPv6 routing and security profiles) without buying newer ISR G2 or G3 hardware. 2.
