Abstract
Abstract A technique for resource distribution using an auto-discovery mechanism for Provider-Provisioned Layer- 2 and Layer- 3 Virtual Private Networks. In one particular exemplary embodiment, the technique may be realized by a method for establishing a Virtual Private Network (VPN) tunnel between a first provider edge (PE) device and a second (PE) device of a provider-provisioned VPN. The method may comprise advertising at least one tunnel-based parameter to one or more PE devices over a network backbone using an auto-discovery mechanism, the one or more PE devices including at least one of the first and second PE devices. The method further may comprise configuring a VPN tunnel between the first and second PE devices based at least in part on the at least one tunnel-based parameter.
