摘要：
Virtual Private Networks (VPNs) are supported in which customers may use popular internet gateway protocol (IGPs) without the need to convert such IGPs, running on customer devices to a single protocol, such as the border gateway protocol (BGP). Scaling problems, which might otherwise occur when multiple instances of an IGP flood link state information, are avoided by using a flooding topology which is smaller than a forwarding topology. The flooding topology may be a fully connected sub-set of the forwarding topology.
