Configuration example
Network requirements
As shown in Figure 70 , two IPv6 networks are connected over an IPv4 network. Configure an IPv6 over
IPv4 tunnel between Switch A and Switch B to make the two IPv6 networks reachable to each other. If the
destination IPv4 address cannot be automatically obtained from the destination IPv6 addresses of
packets, configure an IPv6 manual tunnel.

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