Abstract
This application discloses a fault protection method, including: A first node determines that a first cross-domain node is faulty. The first node is a head node of a segment routing best effort SR-BE service tunnel, the SR-BE tunnel is a cross-domain tunnel that passes through a first IGP domain and a second IGP domain, the SR-BE tunnel passes through the first cross-domain node, and the first cross-domain node is a node that crosses the first IGP domain and the second IGP domain. The first node switches a service transmission path from the SR-BE tunnel to a backup tunnel. The backup tunnel does not pass through the first cross-domain node, and the backup tunnel is a tunnel with a strict explicit path.
