Configuration Guidelines; Configuration Procedure - HP 3600 v2 Series Configuration Manual

Configuration guidelines

Follow these guidelines when you configure an ISATAP tunnel:
Specify a public address or interface as the source address or interface for the tunnel.
•
No destination address needs to be configured for an ISATAP tunnel. The destination address of the
•
tunnel can be automatically obtained through the IPv4 address embedded in the ISATAP address.
• To encapsulate and forward IPv6 packets whose destination address does not belong to the subnet
where the receiving tunnel interface resides, configure a static route to reach the destination IPv6
address through this tunnel interface on the device. Because automatic tunnels do not support
dynamic routing, you can configure a static route to that destination IPv6 address with this tunnel
interface as the outbound interface or the peer tunnel interface address as the next hop. A similar
configuration is required at the other tunnel end. For the detailed configuration, see Layer 3—IP
Routing Configuration Guide.
The automatic tunnel interfaces using the same encapsulation protocol cannot share the same
•
source IP address.

Configuration procedure

To configure an ISATAP tunnel:
Step
1. Enter system view.
2. Enable IPv6.
3. Enter tunnel interface view.
4. Configure an IPv6 address
for the tunnel interface.
5. Specify the ISATAP tunnel
mode.
6. Configure a source
address or interface for the
tunnel.
7. Return to system view.

Configure an IPv6 global unicast
address or site-local address:
ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
ipv6 address
ipv6-address/prefix-length
eui-64
•
Configure an IPv6 link-local
address:
ipv6 address auto link-local
ipv6 address ipv6-address
link-local

Remarks
N/A
By default, the IPv6 forwarding
function is disabled.
N/A
The IPv6 link-local address
configuration is optional.
By default:
•
No IPv6 global unicast address
is configured for the tunnel
interface.
•
A link-local address will
automatically be generated
when an IPv6 global unicast
address or link-local address is
configured.
GRE over IPv4 tunnel by default.
The same tunnel mode should be
configured at both ends of the
tunnel. Otherwise, packet delivery
will fail.
By default, no source address or
interface is configured for the tunnel.
