The problem that presents itself is that these virtual routers need to find each other over a virtual topology and they need to send broadcast datagrams as mandated in routing protocols {[}such as the neighbor discovery datagram and routing updates in OSPF, the routing updates in RIPV2 etc{]} and user data over this virtual topology. This memo presents an approach for solving these problems.}, }
