# Configure an IPv6 over IPv4 manual tunnel interface tunnel 0.
[SwitchB] interface tunnel 0 mode ipv6-ipv4
# Specify VLAN-interface 100 as the source interface of the tunnel interface.
[SwitchB-Tunnel0] source vlan-interface 100
# Specify the destination address for the tunnel interface as the IP address of VLAN-interface 100
of Switch A.
[SwitchB-Tunnel0] destination 192.168.100.1
[SwitchB-Tunnel0] quit
# Configure a static route destined for IPv6 network 1 through tunnel 0 on Switch B.
[SwitchB] ipv6 route-static 3002:: 64 tunnel 0
Verifying the configuration
# Use the display ipv6 interface command to view tunnel interface status on Switch A and Switch B. The
output shows that the interface tunnel 0 is up. (Details not shown.)
# Switch B and Switch A can ping the IPv6 address of VLAN-interface 101 of each other. For example,
ping the IPv6 address of VLAN-interface 101 on Switch B from Switch A.
[SwitchA] ping ipv6 3003::1

Configuring a 6to4 tunnel
Follow these guidelines when you configure a 6to4 tunnel:
• You do not need to configure a destination address for a 6to4 tunnel, because the destination IPv4
address is embedded in the 6to4 IPv6 address.
• The source addresses of local tunnels of the same tunnel mode cannot be the same.
• Because automatic tunnels do not support dynamic routing, you must configure a static route
destined for the destination IPv6 network if the destination IPv6 network is not in the same subnet
as the IPv6 address of the tunnel interface. You can specify the local tunnel interface as the egress
interface of the route or specify the IPv6 address of the peer tunnel interface as the next hop of the
route. For the detailed configuration, see Layer 3—IP Routing Configuration Guide.
