Abstract
Using a routing protocol for network port failover. A network stack, which does not perform reverse path forwarding, includes a first interface as a loopback interface that is assigned a first internet protocol (IP) address, a second interface to a first network port, and a third interface to a second network port. The routing protocol is configured to communicate over the second interface with a first port at remote network device(s), and to communicate over the third interface with a second port at the remote network device(s). A route comprising the first IP address is announced to the remote network device(s), and default route of the network stack is configured to egress IP packets via the second interface. Later, the routing protocol indicates that there is a forwarding failure associated with the second interface, and the default route is configured to egress IP packets via the third interface.
