Configuration example
Network requirements
As shown in Figure 75 , the two subnets Group 1 and Group 2 running IPv6 are connected through an
IPv6 network. Configure an IPv6 over IPv6 tunnel between Switch A and Switch B to make the two
subnets reachable to each other without disclosing their IPv6 addresses to the IPv6 network.

Before configuring an IPv6 over IPv6 tunnel, make sure that Switch A and Switch B have the corresponding
VLAN interfaces created and are reachable to each other.
