Abstract

Embodiments generally relate to enabling encapsulation in networks. In one embodiment, a method includes receiving a message from an edge configuration device, wherein the message contains shortest path bridging (SPB) configuration information. The method also includes performing provider backbone bridge (MAC-in-MAC) encapsulation in response to receiving the message.

First claim

What is claimed is:

1. A method comprising:
receiving, at an edge server device, a link layer discovery protocol (LLDP) message from an edge configuration device,
wherein the LLDP message contains, within the LLDP message, shortest path bridging (SPB) configuration information that includes a binding list with virtual local area network-to-service identification (VLAN to ISID) mapping information to be configured at the edge server device,
wherein the SPB configuration information is configured at the edge configuration device based on the binding list included within the LLDP message,
and wherein the LLDP message contains one or more requests to not bind undesired VLAN to ISID mappings; and
performing provider backbone bridge media access control in media access control (MAC-in-MAC) encapsulation, at the edge server device, in response to receiving the LLDP message.

2. The method of claim 1 , wherein the edge server device receives the LLDP message, and wherein the edge server device performs the MAC-in-MAC encapsulation.

3. The method of claim 1 , wherein the edge server device receives the LLDP message, and wherein the edge server device performs the MAC-in-MAC encapsulation, and wherein the edge configuration device and the edge server device are separate devices.

4. The method of claim 1 , wherein the MAC-in-MAC encapsulation is enabled by the SPB configuration information provided by the edge configuration device.

5. A computer program product comprising a non-transitory computer-readable medium including program instructions executed by a processor to be implemented by a device connected to a communication network, the program instructions for:
receiving, at an edge server device, a link layer discovery protocol (LLDP) message from an edge configuration device,
wherein the LLDP message contains, within the LLDP message, shortest path bridging (SPB) configuration information that includes a binding list with virtual local area network-to-service identification (VLAN to ISID) mapping information to be configured at the edge server device,
wherein the SPB configuration information is configured at the edge configuration device based on the binding list included within the LLDP message,
and wherein the LLDP message contains one or more requests to not bind undesired VLAN to ISID mappings; and
performing provider backbone bridge media access control in media access control (MAC-in-MAC) encapsulation, at the edge server device, in response to receiving the LLDP message.

6. The computer program product of claim 5 , wherein the SPB configuration information is configured at the edge configuration device.

7. The computer program product of claim 5 , wherein the edge server device receives the LLDP message, and wherein the edge server device performs the MAC-in-MAC encapsulation.

8. The computer program product of claim 5 , wherein the edge server device receives the LLDP message, and wherein the edge server device performs the MAC-in-MAC encapsulation, and wherein the edge configuration device and the edge server device are separate devices.

9. The computer program product of claim 5 , wherein the MAC-in-MAC encapsulation is enabled by the SPB configuration information provided by the edge configuration device.

10. A device comprising:
a memory; and
at least one processor configured to access the memory and perform operations comprising:
receiving, at an edge server device, a link layer discovery protocol (LLDP) message from an edge configuration device,
wherein the LLDP message contains, within the LLDP message, shortest path bridging (SPB) configuration information that includes a binding list with virtual local area network-to-service identification (VLAN to ISID) mapping information to be configured at the edge server device,
wherein the SPB configuration information is configured at the edge configuration device based on the binding list included within the LLDP message,
and wherein the LLDP message contains one or more requests to not bind undesired VLAN to ISID mappings; and
performing provider backbone bridge media access control in media access control (MAC-in-MAC) encapsulation, at the edge server device, in response to receiving the LLDP message.

11. The device of claim 10 , wherein the edge server device receives the LLDP message, and wherein the edge server device performs the MAC-in-MAC encapsulation.

12. The device of claim 10 , wherein the edge server device receives the LLDP message, and wherein the edge server device performs the MAC-in-MAC encapsulation, and wherein the edge configuration device and the edge server device are separate devices.

13. The device of claim 10 , wherein the MAC-in-MAC encapsulation is enabled by the SPB configuration information provided by the edge configuration device.

14. The method of claim 1 , wherein the edge configuration device is different from the edge server device.

15. The computer program product of claim 8 , wherein the edge configuration device is different from the edge server device.

16. The device of claim 10 , wherein the edge configuration device is different from the edge server device.
