HSRP (Hot Standby Redundancy Protocol) is a common network gateway redundancy protocol where 2 (or more) routers share a gateway IP. This code short-circuits that relationship by spoofing a partner in this process and redirecting traffic to the client running it. This software is for testing purposes only.

NOTE: As with any tool, it can be misused. Only use tools such as this on networks you own or have received explicit, written permission to test on. I recommend using VirtualBox and GNS3 in order to give you a safe environment to play.
