Configuring An Ipv4 Over Ipv6 Tunnel - HP 6125XLG Layer 3-Ip Services Configuration Manual

# Create an IPv4 over IPv4 tunnel interface tunnel 2.
[SwitchB] interface tunnel 2 mode ipv4-ipv4
# Specify an IPv4 address for the tunnel interface.
[SwitchB-Tunnel2] ip address 10.1.2.2 255.255.255.0
# Specify the IP address of VLAN-interface 101 as the source address for the tunnel interface.
[SwitchB-Tunnel2] source 3.1.1.1
# Specify the IP address of VLAN-interface 101 on Switch A as the destination address for the
tunnel interface.
[SwitchB-Tunnel2] destination 2.1.1.1

# Configure a static route destined for the IP network Group 1 through the tunnel interface.

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 VLAN-interface 100 from each switch. This example uses
Switch A.

Configuring an IPv4 over IPv6 tunnel

Follow these guidelines when you configure an IPv4 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.
• The source/destination addresses of local tunnels of the same tunnel mode cannot be the same.
If the destination IPv4 network is not on the same subnet as the IPv4 address of the local tunnel
•
interface, you must configure a route destined for the destination IPv4 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.
