In your script, you give every node a default route.
Default routes are fine for nodes with one neighbor,
but for nodes with multiple neighbors they're not sufficient.
(A default route says "all data that I don't otherwise know how to
route will go here"---if you have multiple neighbors, clearly that
doesn't let you send to all of them.)
You need to fix routing for your node 2.
