mpls over microwave

[elouie at techintegrity.com (Eric Louie)]

because I have a partial implementation of MPLS routers. Whether the
routers support MPLS or not, the routing on an OSPF level doesn't depend on
MPLS being enabled.  Eventually everything will be MPLS-capable.  The MPLS
network is not multiple-path.  The OSPF network is.
