The invention provides a routing processing method and apparatus. According to the routing processing method and apparatus provided by the invention, a network device maintains a routing identifier mapping table and synchronizes the routing identifier mapping table to a backup apparatus, after the network device executes GR, if the network device learns routing, and when a path-id allocated to the routing before the network device executes the GR is present in the routing identifier mapping table, the path-id previously allocated by the present network device to the routing is still used as the path-id of the currently learnt routing, and thus the path-id of the same routing before and after the network device executes the GR is invariable.
