Abstract

Embodiments of the present disclosure provide a data transmission method, a network device, a storage medium, and a computer program product. At the network layer, a neighbor discovery protocol carrying SRv Locator and/or SRv Capability of the first network device is sent. So that the second network device may obtain SRv < 6 > Locator and/or SRv < 6 > Capability of the first network device. In addition, at the link layer, by sending a link layer discovery protocol carrying SRv Locator and/or SRv Capability of the first network device, the second network device may obtain SRv Locator and/or SRv6Capability of the first network device according to the link layer discovery protocol. Thus, the dynamic release of the route information of the first network device is realized by using two mutually non-conflicting protocols.
