Abstract
In general, techniques are generally described for reducing or preventing transient black-holing of network traffic in an overlay network. A method includes executing, by a network device included in a link state domain, an Interior Gateway Protocol (IGP) to exchange link-state messages with at least one remote network device in the link-state domain; generating, by the network device, an IGP link-state message that includes link overload information to overload a link in the link-state domain that couples the network device to the remote network device; and sending, by the network device and to the at least one other network device, the IGP link-state message that includes the link overload information to direct the remote network device to stop sending network traffic to the network device using the overloaded link.
