Ok first question. In you post you have the following below. YOu will notice its pointing to :2:2 however there is no :2:2 network on any of the routers is this a typo did you mean to say :23:23::??? also its a 64 instead of a 128 which is what the loopback is. However maybe all addresses are held within the 128?? So your just pointing to a non-existent address knowing that since the one is a prefix of 128 that can hold all addresses so its being sent that way. very cryptic though and I wanted to confirm.
if this is just a typo then you might want to fix that one and the one below it to as both refer to a :2:2 where none exist.
also my follow up question is this. a floating route just means you have two static routes and if one goes down there is another one so that is called a floating static route?
