As mentioned earlier, ''configuration scheme 2'' (figure above) is an extension of ''configuration scheme 1''. While ''configuration scheme 1'' only depicts a connection between two IPsec instances, you can see that in ''configuration scheme 2'' additionally contains two end devices ('''END1''' and '''END2'''), each connected to a separate router's LAN. When this scheme is realized, not only will the two routers be able to communicate with each other, the end devices will also be reachable to one another and from each router. | As mentioned earlier, ''configuration scheme 2'' (figure above) is an extension of ''configuration scheme 1''.
