FILTERING ADVERTISING OF ROUTE ADVERTISEMENTS BASED ON VIRTUAL NETWORK IDENTIFIERS

Abstract:

Virtual network identifiers are extracted from route advertisements. A table associates virtual network identifiers with provider edge devices. When a virtual network identifier extracted from a route advertisement matches a virtual network identifier in the table, the route advertisement is propagated to the provider edge devices associated with that virtual network identifier in the table. The route advertisement is not propagated to provider edge devices not associated with that virtual network identifier in the table.
