Embodiments of the present invention provide a routing method and a routing apparatus. The routing method includes: receiving a first data packet sent by a first mobile node to a first communication peer end, where the first mobility router is a mobility router in a visited network of the first mobile node, and the first data packet includes an address of the first communication peer end; acquiring an address of a proxy routing entity based on the address of the first communication peer end, where the proxy routing entity is located in a communication path between the first mobility router and the first communication peer end; establishing a first tunnel to the proxy routing entity based on the address of the proxy routing entity; and transmitting, by using the first tunnel, a data packet sent by the first communication peer end to the first mobile node.
