This figure once again uses the illustration from the previous figures of the home and visited networks. Here, however, the visited network has been replaced by a "Foreign network being visited at session start." This network includes a router, labeled "Anchor foreign agent," a link-layer switch, and the mobile node, which has been grayed out. A new network, labeled "New foreign network," has been added adjacent to the foreign network being visited at session start. This new network includes a router, labeled "New foreign agent," a link-layer switch, and a mobile node.

A blue arrow, labeled 1 and corresponding to numbered steps given in the text on page 571, extends from the Corresponding Agent to the Foreign Anchor Agent. A thicker blue arrow labeled 2 extends from the grayed-out mobile node in the foreign network being visited at session start to the mobile node in the new foreign network. A blue line labeled 3 points back and forth between the New Foreign Agent and the Mobile Node in the new foreign network. A blue line labeled 4 points back and forth between the Anchor Foreign Agent and the New Foreign Agent. And a blue line labeled 5 extends from the Anchor Foreign Agent to the Mobile Node in the new foreign network.
