Abstract
In a data transfer network, a network device () receives at its first data interface an identifier message transferred via a first data transfer path from another network device (). The network device compares the identifier message to earlier received identifier messages. If the identifier message matches an earlier received identifier message received at another data interface and transferred via a second data transfer path from the other network device, the network device updates its forwarding database to express that the other network device is accessible also via the first data interface, and transmits address information related to the other network device via the first data interface so as to determine the first data transfer path to be an alternative for the second data transfer path. The first and second data transfer paths can be used for protecting each other and/or for load sharing.
