Abstract: Provided are a method and apparatus for protecting master and slave access network elements in a data communication network. The method includes: the master access network element detects connectivity between the master access network element and a target network; and when detecting the master access network element is not connected with the target network, invalidates master static routing from the master access network element to a network management server and floods routing change situations. An internal network element detects whether master static routing from a master access network element to the network management server is invalid; and when detecting that the master static routing is invalid, the internal network element re-performs routing calculation, and completes switching from the master static routing to slave static routing; the slave static routing is routing information from the slave network element to the network management server learned by the internal network element in advance.
