# Specify the IP address of VLAN-interface 101 on Switch A as the destination address for the
tunnel interface.

# Configure a static route destined for the IPv6 group 1 through the tunnel interface.
[SwitchB] ipv6 route-static 2002:1:: 64 tunnel 2
Verifying the configuration
# Use the display ipv6 interface command to display the status of the tunnel interfaces on Switch A and
Switch B. Verify that the tunnel interfaces are up. (Details not shown.)
# Verify that Switch A and Switch B can ping the IPv4 address of the peer interface. This example uses
Switch A.

Displaying and maintaining tunneling configuration
Execute display commands in any view and reset commands in user view.
Task Command
Display information about tunnel interfaces.
display interface tunnel [ number [ brief [ description ] ] | brief
[ description | down ] ]
Display IPv6 information on tunnel interfaces. display ipv6 interface [ tunnel [ number ] ] [ brief ]
Clear statistics on tunnel interfaces. reset counters interface [ tunnel [ number ] ]
Troubleshooting tunneling
Symptom
A tunnel interface configured with related parameters such as tunnel source address, tunnel destination
address, and tunnel mode cannot come up.
Analysis
The physical interface of the tunnel does not come up, or the tunnel destination is unreachable.
