According to an example, in a method for calculating a route, a first network device may add a protocol attribute supported by a link to a link state protocol data unit (LSP) of the first network device according to a protocol attribute supported by a port of the first network device and a protocol attribute supported by a port of a neighbor network device when establishing an adjacency, and may flood the LSP. The first network device may receive a LSP from a neighbor network device, parse a protocol attribute supported by a link contained in the received LSP, record the protocol attribute supported by the link contained in the received LSP in local network topology information, to obtain updated network topology information. And the first network device may calculate a route according to the updated network topology information. A network device and a computing device may calculate a route.
