Abstract
Aspects of the subject disclosure may include, for example, instantiating a virtual provider edge router (VPE) of a network operator on a layer 3 public cloud network operated by a cloud operator, establishing a virtual layer 2 bridging domain over the layer 3 public cloud network between a core network of the network operator and the VPE, wherein the virtual layer 2 bridging domain shields infrastructure addressing of the core network of the network operator, and establishing an Interior Gateway Protocol (IGP) of the network operator on top of the virtual layer 2 bridging domain for layer 2 communication between the core network of the network operator and the VPE over the layer 3 public cloud network. Other embodiments are disclosed.
Claims20
A device, comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- instantiating a virtual provider edge router (VPE) on a data processing system of a public cloud network operated by a cloud operator, wherein the public cloud network communicates data according to layer 3;
- establishing a virtual layer 2 bridging domain over the public cloud network between a core network of a network operator and the VPE;
- and
- providing network services of the network operator at the VPE, wherein the layer 2 bridging domain shields infrastructure addressing of the core network of the network operator.
A non-transitory, machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- providing instructions and data to a server of a public cloud network operated by a cloud operator, the instructions and data operative to instantiate on the server a virtual provider edge router (VPE) of a network provider, wherein the public cloud network communicates layer 3 data;
- extending a layer 2 domain of a core network of the network provider over the public cloud network to the VPE;
- and
- extending an Interior Gateway Protocol (IGP) of the network provider over the layer 2 domain of the core network to communicate between the core network of the network provider and the VPE as if the VPE is a part of the core network of the network provider.
A method, comprising:
- instantiating, by a processing system including a processor, a virtual provider edge router (VPE) of a network operator on a layer 3 public cloud network operated by a cloud operator;
- establishing, by the processing system, a virtual layer 2 bridging domain over the layer 3 public cloud network between a core network of the network operator and the VPE, wherein the virtual layer 2 bridging domain shields infrastructure addressing of the core network of the network operator;
- and
- establishing, by the processing system, an Interior Gateway Protocol (IGP) of the network operator on top of the virtual layer 2 bridging domain for layer 2 communication between the core network of the network operator and the VPE over the layer 3 public cloud network.
