Verifying the configuration
# Use the display interface tunnel command to display the status of the tunnel interfaces on Switch A and
Switch B. The output shows that the tunnel interfaces are up. (Details not shown.)
# Ping the IPv4 address of the peer interface from each switch. The following shows the output on Switch
A.

Configuring an IPv6 over IPv6 tunnel
Follow these guidelines when you configure an IPv6 over IPv6 tunnel:
• The destination address specified for the local tunnel interface must be the source address specified
for the peer tunnel interface, and vice versa.
• Two or more local tunnel interfaces using the same encapsulation protocol must have different
source and destination addresses.
• The IPv6 address of the tunnel interface must not be on the same subnet as the destination address
configured for the tunnel interface.
• If the destination IPv6 network is not on the same subnet as the IPv6 address of the local tunnel
interface, you must configure a route destined for the destination IPv6 network through the tunnel
interface. You can configure a static route, and specify the local tunnel interface as the egress
interface or specify the IPv6 address of the peer tunnel interface as the next hop. Alternatively, you
can enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose. For
the detailed configuration, see Layer 3—IP Routing Configuration Guide.
• The destination address of the route passing the tunnel interface must not be on the same subnet as
the destination address configured for the tunnel interface.
