This section describes the operation of the configuration to create a highly reliable network using guest OSes of Hyper-V.
For the operation of GLS in Hyper-V, there is no difference from the operation on a physical server.
NIC switching mode is provided as an example in this section.
NIC switching mode
GLS on a guest OS performs HUB monitoring (ping monitoring) for HUB1 placed outside the server. If a failure occurred on HUB1, GLS switches the path from the primary interface (eth0) to the secondary interface (eth1) to keep connection. In addition, the active NIC becomes NIC2 after the connection is switched to eth1. Then, HUB monitoring (ping monitoring) is performed for HUB2 via the virtual switch 2 and the active NIC (NIC2).
