Claims
- 1. A method for supporting mobile routers in IPv6, comprising:
obtaining, by a mobile router, a care-of-address associated with an address configuration; registering, by the mobile router, the care-of-address with a home agent; establishing, by the mobile router, a bi-directional tunnel between the mobile router and the home agent; and forwarding configuration information via the bi-directional tunnel employing an address associated with a mobile network.
- 2. The method of claim 1, further comprising requesting that packets that include an address prefix within a set of prefixes be forwarded to the mobile router.
- 3. The method of claim 1, wherein the configuration information is static.
- 4. The method of claim 1, wherein the configuration information is dynamic.
- 5. The method of claim 1, wherein the configuration information is routing information.
- 6. The method of claim 1, wherein the mobile router obtains the care-of-address while attaching to a network, the network associated with a network address, the network address including a prefix, and wherein the care-of-address associated with an address configuration is generated by combining the prefix with an identifier that identifies the mobile router.
- 7. The method of claim 1, wherein the mobile router obtains the care-of-address by at least one of a stateless address autoconfiguration, and a stateful address configuration.
- 8. The method of claim 1, further comprising encapsulating the configuration information.
- 9. The method of claim 1, further comprising:
receiving, at the home agent, a packet that includes a home address of the mobile router; and forwarding the packet via the bi-directional tunnel to the mobile router.
- 10. The method of claim 9, further comprising employing the home address to retrieve the care-of-address from a table included on the home agent.
- 11. A method for supporting mobile routers in IPv6, comprising:
updating, by a home agent, a routing table wherein the routing table includes a routing entry associated with a mobile router that is reachable from the home agent; receiving, by the home agent, a packet; selecting, by the home agent, a bi-directional tunnel associated with the mobile router; tunneling, by the home agent, the packet to the mobile router.
- 12. The method of claim 11, wherein the packet is destined to the mobile router.
- 13. The method of claim 11, wherein the packet is destined to a node on a mobile network reachable through the mobile router.
- 14. The method of claim 11, further comprising tunneling, by the mobile router, another packet to the home agent.
- 15. The method of claim 14, further comprising receiving, by the mobile router, the other packet from a node on a mobile network reachable through the mobile router.
- 16. The method of claim 11, further comprising:
performing a lookup into a binding cache to obtain a care-of-address associated with the mobile router.
- 17. A system for supporting mobile routers in IPv6, comprising:
a mobile router; a home agent; and a bi-directional tunnel connecting the mobile router to the home agent, wherein the home agent is configured to perform acts, comprising:
receiving a packet that includes a home address of the mobile router, and forwarding the packet via the bi-directional tunnel to the mobile router, wherein the packet includes an address associated with a mobile network.
- 18. The system of claim 17, wherein the bi-directional tunnel is configurable.
- 19. The system of claim 18, wherein the bi-directional tunnel is statically configurable.
- 20. The system of claim 18, wherein the bi-directional tunnel is dynamically configurable.
- 21. A system for supporting mobile routers in IPv6, comprising:
means for forwarding packets to a mobile network; means for receiving packets at a home network; and a bi-directional tunnel connecting the means for forwarding packets to the means for receiving packets, wherein a packet that includes a home address of the means for forwarding packets and that is received by the means for receiving packets is forwarded through the bi-directional tunnel to the means for forwarding packets to the mobile network.
