Abstract
The present disclosure discloses a method and network device for home VLAN identification for roaming mobile clients. Specifically, the disclosed method and system detects that the mobile client has roamed away from a first network to a second network, maintains a mapping between a virtual local area network (VLAN) corresponding to the mobile client and a tunnel corresponding to a foreign agent in the second network, and forwards packets to or from the mobile client on the VLAN based on the mapping between the VLAN and the tunnel via which the packets are received. Therefore, the disclosed method and system allows for identification of home VLANs for roaming mobile clients without merging VLAN policy configurations at the home agent and the foreign agent.
