config ip_tunnel isatap
Purpose
Used to configure an IPv6 ISATAP tunnel.
Syntax
config ip_tunnel isatap <tunnel_name 12> {ipv6address <ipv6networkaddr> | source
<ipaddr>}(1)
Description
The config ip_tunnel isatap command is used to configure an existing IPv6 tunnel as an IPv6
ISATAP tunnel on the switch. If this tunnel has previously been configured in another mode,
the tunnel’s information will still exist in the database. However, whether the tunnel’s former
information is invalid or not will depend on the current mode. IPv6 ISATAP tunnels are point-
to-multipoint tunnels that can be used to connect 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
link local or global prefixes), a 32-bit value 0000:5EFE and a 32-bit tunnel source IPv4
address.
Parameters
<tunnel_name 12>
- IPv6 Tunnel interface name, maximum of 12 characters.
ipv6address <ipv6networkaddr>
- The IPv6 address assigned to this IPv6 tunnel interface.
IPv6 processing would be enabled on this 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.
source <ipaddr>
- The source IPv4 address of this IPv6 tunnel interface. It is used as the
source address for packets in this IPv6 tunnel. The tunnel destination IPv4 address is
extracted from the last 32 bits of the remote tunnel endpoint’s IPv6 ISATAP address.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
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-3627:admin#
config ip_tunnel isatap tn2 source 10.0.0.1
Command: config ip_tunnel isatap tn2 source 10.0.0.1
Success.
DGS-3627: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-3627:admin#
show ip_tunnel
Purpose
Used to show one or all IPv6 tunnel interfaces’ information.
Syntax
show ip_tunnel {<tunnel_name 12>}
Description
The show ip_tunnel command is used to show one or all IPv6 tunnel interfaces’ information.
Parameters
<tunnel_name 12>
- IPv6 Tunnel interface name, maximum of 12 characters.
If no tunnel is specified, all tunnels on the Switch will be displayed.
Restrictions
None.
Example usage:
To show an IPv6 tunnel interface’s information (Tunnel name is “tn2”):
