Loose Source Routing, an IP option which can be used for address translation. LSR is also used to implement mobility in IP networks. [1]
Loose source routing use a source routing option in TCP/IP to record the set of routers a packet must visit. The destination of the packet is replaced with the next router the packet must visit. By setting the forwarding agent(FA) to one of the routers the packet must visit, LSR is equivalent to tunneling. If the corresponding node stores the LSR options and reverses it, it is equivalent to the functionality in mobile IPv6.
The name loose source routing comes from the fact that only part of the path is set in advanced.[2] This is in contrast with strict source routing in which every step of the route would be decided in advance when the packet was sent.
