S9300&S9300E Terabit Routing Switch
Configuration Guide - IP Service
Follow-up Procedure
The configuration of 6to4 relay needed to access the IPv6 network, is similar to the 6to4 tunnel.
For the configuration example, see "Example for Configuring 6to4 Relay."

11.4.5 Configuring an ISATAP Tunnel

Intra-site Automatic Tunnel Addressing Protocol (ISATAP) tunnels are used in the situation
where IPv4/IPv6 hosts in an IPv4 network need to access an IPv6 network. An ISATAP tunnel
can be established between an ISATAP host and an ISATAP device.
Context
Note the following when configuring an ISATAP tunnel:

Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface tunnel interface-number
A tunnel interface is created.
Step 3 Run:
tunnel-protocol ipv6-ipv4 isatap
The tunnel is specified as an ISATAP tunnel.
Step 4 Run:
source { ip-address | interface-type interface-number }
The source address or source interface of the tunnel is specified.
Step 5 Run:
ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length }
The tunnel interface is configured with an IPv6 address.
Step 6 Run:
undo ipv6 nd ra halt
Issue 01 (2012-03-15)
Before configuring other parameters of the tunnel, create a tunnel interface.
When the specified source interface of the tunnel is a physical interface, it is recommended
to set the tunnel ID to be the same as the number of the physical interface.
When configuring an ISATAP tunnel, you need to specify only the source address of the
tunnel. The destination address of the tunnel is automatically obtained from the destination
IP address field carried in the original IPv6 packet. Note that the source interface of the
ISATAP tunnel must be unique.
The IPv6 address configured on the tunnel interface is an ISATAP address with a prefix
length of 64 bits.
