Provided are methods and apparatuses for updating a route. In the present disclosure, when an access device receives a first host route and a first sequence number sent by a BGP peer of the access device, regardless of the value of the first sequence number, the first host route is used as a route used by the access device to forward data to a target host, and a recorded first ARP entry corresponding to the target host is deleted, so as to trigger the BGP peer of the access device, for example, a convergence device, to withdraw host routes associated with the first ARP entry based on the existing route withdrawal mechanism.
