SYMPTOMS

A host computer may lose the connection to one of its gateways.

CAUSE

If a computer that is configured to use Internet Router Discovery Protocol (IRDP) temporarily stops receiving router advertisements from a gateway interface and the default gateway detection routine discovers that the interface is invalid, the route to that gateway interface is deleted from the route table on the computer. If the gateway becomes valid again and starts sending IRDP updates to the computer, the route is not added again.
