Verifying the configuration
# Use the display interface tunnel 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.
[SwitchA] ping -a 30.1.1.1 30.1.3.1
Ping 30.1.3.1 (30.1.3.1) from 30.1.1.1: 56 data bytes, press CTRL_C to break
56 bytes from 30.1.3.1: icmp_seq=0 ttl=255 time=3.000 ms
56 bytes from 30.1.3.1: icmp_seq=1 ttl=255 time=1.000 ms
56 bytes from 30.1.3.1: icmp_seq=2 ttl=255 time=0.000 ms

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.
• The source/destination addresses of local tunnels of the same tunnel mode cannot be the same.
• The IPv6 address of the tunnel interface must not be on the same subnet as the destination address
configured for the tunnel interface.
• To ensure correct packet forwarding, identify whether the destination IPv6 network and the IPv6
address of the local tunnel interface are on the same subnet. If they are not, configure a route
reaching the destination IPv6 network through the tunnel interface. You can configure the route by
using one of the following methods:
{
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.
{
Enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose.
For more information about route 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.
To configure an IPv6 over IPv6 tunnel:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 tunnel interface
view. interface tunnel number [ mode
ipv6 ]
N/A
3. Configure an IPv6 address for
the tunnel interface.
See " Configuring basic IPv6
settings ."
By default, no IPv6 address is
configured for the tunnel
interface.
