Method and apparatus for controlling multiple registration protocol (MRP) scope using MRP policies
A Multiple Registration Protocol (MRP) advertisement control capability is provided. A method includes receiving an MRP advertisement at a device configured as an interface between a core domain and a local domain and determining handling of the MRP advertisement at the device using at least one MRP policy stored on the device. The core domain may be a Provider Backbone Bridging (PBB) network or other suitable core network. The local domain may be one of a PBB network, a Provider Bridging Network (PBN), a Metropolitan Area Network (MAN), and the like. In one case, when the MRP advertisement is associated with a local service of the local domain, the MRP policy indicates that the MRP advertisement is not to be forwarded via the core domain. In one case, when the MRP advertisement is associated with an inter-domain service supported by the local domain, the MRP policy indicates that the MRP advertisement is to be forwarded to the core domain when received from the local domain and is to be forwarded to the local domain when received from the core domain.
1. A method, comprising:
receiving Multiple Registration Protocol (MRP) advertisements at a device configured as an interface between a core domain and a local domain, wherein the device has an MRP policy stored thereon;
forwarding a first one of the received MRP advertisements between the core domain and the local domain in accordance with the MRP policy indicating that MRP advertisements associated with an inter-domain service of the local domain are to be forwarded between the core domain and the local domain; and
blocking a second one of the received MRP advertisements from being forwarded via the core domain in accordance with the MRP policy indicating that MRP advertisements associated with a local service of the local domain are not to be forwarded via the core domain;
wherein the MRP policy comprises a first rule associated with a first service identifier of the local service and a second rule associated with a second service identifier of the inter-domain service.
2. The method of claim 1 , wherein the core domain is a Provider Backbone Bridging (PBB) network.
3. The method of claim 1 , wherein the local domain is one of a Provider Backbone Bridging (PBB) network, a Provider Bridging Network (PBN), and a Metropolitan Area Network (MAN).
4. The method of claim 1 , wherein the MRP policy comprises a third rule associated with a third service identifier of a service not supported by the local domain.
5. The method of claim 4 , wherein the third rule indicates that MRP advertisements associated with the third service identifier of the service not supported by the local domain are not to be forwarded within the local domain.
6. An apparatus, comprising:
a processor configured for:
receiving Multiple Registration Protocol (MRP) advertisements at a device configured as an interface between a core domain and a local domain,
wherein the device has an MRP policy stored thereon;
forwarding a first one of the received MRP advertisements between the core domain and the local domain in accordance with the MRP policy indicating that MRP advertisements associated with an inter-domain service of the local domain are to be forwarded between the core domain and the local domain; and
blocking a second one of the received MRP advertisements from being forwarded via the core domain in accordance with the MRP policy indicating that MRP advertisements associated with a local service of the local domain are not to be forwarded via the core domain;
wherein the MRP policy comprises a first rule associated with a first service identifier of the local service and a second rule associated with a second service identifier of the inter-domain service.
7. The apparatus of claim 6 , wherein the core domain is a Provider Backbone Bridging (PBB) network.
8. The apparatus of claim 6 , wherein the local domain is one of a Provider Backbone Bridging (PBB) network, a Provider Bridging Network (PBN), and a Metropolitan Area Network (MAN).
9. The apparatus of claim 6 , wherein the MRP policy comprises a third rule associated with a third service identifier of a service not supported by the local domain.
10. The apparatus of claim 9 , wherein the third rule indicates that MRP advertisements associated with the third service identifier of the service not supported by the local domain are not to be forwarded within the local domain.
11. A non-transitory computer-readable storage medium storing instructions which, when executed by a computer, cause the computer to perform a method, the method comprising:
receiving Multiple Registration Protocol (MRP) advertisements at a device configured as an interface between a core domain and a local domain, wherein the device has an MRP policy stored thereon;
forwarding a first one of the received MRP advertisements between the core domain and the local domain in accordance with the MRP policy indicating that MRP advertisements associated with an inter-domain service of the local domain are to be forwarded between the core domain and the local domain; and
blocking a second one of the received MRP advertisements from being forwarded via the core domain in accordance with the MRP policy indicating that MRP advertisements associated with a local service of the local domain are not to be forwarded via the core domain;
wherein the MRP policy comprises a first rule associated with a first service identifier of the local service and a second rule associated with a second service identifier of the inter-domain service.
12. The non-transitory computer-readable storage medium of claim 11 , wherein the core domain is a Provider Backbone Bridging (PBB) network.
13. The non-transitory computer-readable storage medium of claim 11 , wherein the local domain is one of a Provider Backbone Bridging (PBB) network, a Provider Bridging Network (PBN), and a Metropolitan Area Network (MAN).
14. The non-transitory computer-readable storage medium of claim 11 , wherein the MRP policy comprises a third rule associated with a third service identifier of a service not supported by the local domain.
15. The non-transitory computer-readable storage medium of claim 14 , wherein the third rule indicates that MRP advertisements associated with the third service identifier of the service not supported by the local domain are not to be forwarded within the local domain.
