Try "no peer neighbor-route" on the multilink interfaces, that should get rid of your /32. It is part of ppp, when the negotiation takes place a /32 is input for the other side. I do not use multilink unless it cannot be avoided, I have had issues that make the use of it unappealing. Is there any reason you can't just use CEF or fast switching and have multiple routes to the spokes, one down each T1? If you are using CEF, it is more efficient to do it this way because there is no overhead. In multilink each packet gets an additional 4 byte (I think) header. By the way, I believe that the virtual template method is outdated and no longer used. You don't need it anyway, just the multilink interface and the serials specified as part of it. Of course this assumes that you are using a recent IOS version. HTH.
