ABSTRACT:
Routing information is distributed interdomain using a policy-based protocol and intradomain by flooding. A network device receives a message with routing information from outside its domain and applies policy. Policy filtered routing information is flooded throughout the domain of the network device. A link state advertisement header is added to the routing information to perform flooding. Policy is also applied to flooded routing information before sending such message to another domain.
