When a wireless user accesses the network through IPv6, if the user’s IPv6 address adopts stateless address allocation, there may be cases where the wireless user will apply for IPv6 addresses in two different network segments at the same time after Layer 3 roaming. There may be anomalies in wireless users communicating using IPv6.

When a wireless user accesses the network through IPv6, if the user’s IPv6 address adopts stateless address allocation, there may be cases where the wireless user will apply for IPv6 addresses in two different network segments at the same time after Layer 3 roaming. There may be anomalies in wireless users communicating using IPv6.

① Use DHCPv6 protocol to assign IPv6 addresses to wireless users; 

② Plan the network to avoid Layer 3 roaming; 

③ When applying for two IPv6 addresses at the same time, you can disconnect the wireless connection and reconnect to the network.
