Abstract
Embodiments of this application disclose a route information processing method and an apparatus, which may be used for a network device that supports a BGP protocol, to resolve a defect in an existing BGP SPF protocol. The network device may be a forwarding device, for example, a router or a switch. For example, in embodiments of this application, a priority attribute is introduced to route information that carries NLRI through an extended BGP protocol, to indicate a priority of the route information. This influences a BGP NLRI selection process performed by the network device. For example, embodiments of this application provide a network fault processing method, to help resolve a problem that a network device cannot calculate a packet forwarding path in some scenarios in an existing protocol.
