Abstract
The present invention discloses a method and device for detecting connectivity termination in an IPv6 access network based on a DHCP service model. The method for detecting connectivity termination according to the invention comprises the steps of: creating an entry of the subscriber connectivity cache list corresponding to the subscriber terminal in the access node when the IPv6 connectivity between the subscriber terminal and the access node is established successfully; querying the entry of the neighbor cache list corresponding to the subscriber terminal based on the polling time set in the entry of the subscriber connectivity cache list; deciding whether the connectivity of the subscriber terminal is normal based on the entry information corresponding to the subscriber terminal of the subscriber connectivity cache list and neighbor cache list; and performing termination processing on the connectivity of the subscriber terminal logging off abnormally.
