Configuration procedure
Before configuring an IPv4 over IPv6 tunnel, make sure that Switch A and Switch B have the
corresponding VLAN interfaces created and can reach each other.
Configure Switch A:
•
# Enable IPv6.
<SwitchA> system-view
Command
system-view

destination ipv6-address
Figure 68, the two subnets Group 1 and Group 2 are connected over an IPv6 network.
