Once you have acquired the .bin file, here is how you typically deploy it: 1. In GNS3 Open GNS3 and go to . Navigate to IOS Routers and click New .
The 3725 is a MIPS-based router, which makes it easy for GNS3 (via Dynamips) to emulate. Unlike newer ISR images, it consumes very little RAM and CPU.
Because it’s an "Adventerprise" image, it supports almost every protocol needed for labbing, including MPLS and advanced IPv6.
