System and method for managing routers and communication interfaces on a computing device |
摘要 |
An apparatus and method are described for managing router and communication interfaces. For example, one embodiment of a method implemented on a computing device having a plurality of communication interfaces comprises: receiving a plurality of router advertisement packets indicating a preference level of each of a plurality of routers, each of the plurality of routers reachable through one of the communication interfaces on the computing device; designating one of the communication interfaces as a primary interface and the remainder of the communication interfaces as scoped interfaces; specifying a primary router for the primary interface based on a preference level associated with the primary router, the primary router selected from a group of all of the routers reachable through the primary interface; and specifying a default router for each of the scoped interfaces based on a preference level of each default router, each default router selected from a group of all of the routers reachable through its scoped interface. |

1. A method implemented on a computing device having a plurality of communication interfaces comprising:
receiving a plurality of router advertisement packets indicating a preference level of each of a plurality of routers, each of the plurality of routers reachable through one of the communication interfaces on the computing device; designating one of the communication interfaces as a primary interface and the remainder of the communication interfaces as scoped interfaces, wherein each scoped interface is used for routing communications that comprise a reference to the scoped interface, and the primary interface is an unscoped interface that is used for routing communications that do not comprise a reference to an interface; specifying a primary router for the primary interface based on a preference level associated with the primary router, the primary router selected from a group of routers reachable through the primary interface; and specifying a default router for each of the scoped interfaces based on a preference level of each default router, each default router selected from a group of routers reachable through the corresponding scoped interface; wherein the primary router specified for the primary interface has a preference level which is relatively lower than a preference level for at least one of the routers associated with the scoped interfaces. |
