systems within a site. An IPv6 ISATAP address is a well-defined unicast address that includes a 64-bit
unicast IPv6 prefix (it can be either link-local or global prefixes), a 32-bit value 0000:5EFE and a 32-bit
tunnel source IPv4 address.
Format
config ip_tunnel isatap <tunnel_name 12> {ipv6address <ipv6networkaddr> | source
<ipaddr>}(1)
Parameters
<tunnel_name 12> - Enter the IP tunnel interface name used here. This name can be up to 12
characters long.
ipv6address - (Optional) Specifies the IPv6 address assigned to this IPv6 tunnel interface. IPv6
processing will be enabled on the IPv6 tunnel interface when an IPv6 address is configured.
The last 32 bits of the IPv6 ISATAP address correspond to an IPv4 address assigned to the
tunnel source.
<ipv6networkaddr> - Enter the IPv6 address used here.
source - (Optional) Specifies the source IPv4 address of this IPv6 tunnel interface. It is used as
the source address for packets in the IPv6 tunnel. The tunnel destination IPv4 address is
extracted from the last 32 bits of the remote tunnel endpoint's IPv6 ISATAP address.
<ipaddr> - Enter the source IPv4 address used here.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To configure an IPv6 ISATAP tunnel (Tunnel name is "tn2", Tunnel source IPv4 address is 10.0.0.1,
Tunnel IPv6 address is 2001::5efe:a00:1/64):
DGS-3420-28SC:admin# config ip_tunnel isatap tn2 source 10.0.0.1
Command: config ip_tunnel isatap tn2 source 10.0.0.1
Success.
DGS-3420-28SC:admin# config ip_tunnel isatap tn2 ipv6address 2001::5efe:a00:1/64
Command: config ip_tunnel isatap tn2 ipv6address 2001::5efe:a00:1/64
Success.
DGS-3420-28SC:admin#
