Abstract: A multi-homing load balancing system includes a plurality of router devices that are coupled to a client device. The client device receives a respective router advertisement from each of the plurality of router devices that includes a link-local address for that router device. In response, the client device provides a neighbor solicitation to each of the plurality of router devices that includes the plurality of link-local addresses that were received in the router advertisements. One of the plurality of router devices then responds to the neighbor solicitation by selecting a first link-local address of the plurality of link-local addresses that were included in the neighbor solicitation and providing the first link-local address to the client device in a neighbor advertisement. The client device selects a first router device associated with the first link-local address as a default router device in response to receiving the neighbor advertisement.

Abstract: An information handling system is provided. The information handling system includes a plurality of network devices. One of the plurality of network devices is a source device and another of the plurality of network devices is a destination device. If path maximum transmission unit (PMTU) information for a path between the source device and the destination device is not known, the source device sends a PMTU send packet to the destination device, and the destination device sends a PMTU receive packet with a received PMTU value to the source device. Other associated systems and methods for PMTU discovery are also provided.

Abstract: A multi-homing Internet service provider switchover system includes a plurality of Internet service provider systems and a respective router device coupled to each Internet service provider system. Each router device is configured to determine that a route to its respective Internet service provider system is unavailable and, in response, advertise as a non-default router device with router lifetime information and lifetime information for an address of its respective Internet service provider system set to zero. A client device receives a router advertisement from a first router device that was selected as a default router device, and determines that it includes lifetime information for an address of its first Internet service provider system set to zero. In response, the client device selects a second router device as the default router device such that traffic is switched from the first router device to the second router device.
