6.7 Tunnel Interface Specific Commands
The ZyWALL uses tunnel interfaces in Generic Routing Encapsulation (GRE), IPv6 in IPv4, and 6to4
tunnels. This section covers commands specific to tunnel interfaces. Tunnel interfaces also use
many of the general interface commands discussed at the beginning of
tunnels. This section covers commands specific to tunnel interfaces. Tunnel interfaces also use
many of the general interface commands discussed at the beginning of
.
Use these commands to add, edit, activate, deactivate, or delete tunnel interfaces. You must use
the
the
configure terminal
command to enter the configuration mode before you can use these
commands. GRE mode tunnels support ping check. See
for more on ping
check.

Tunnel Interface Commands
COMMAND
DESCRIPTION
[no] interface tunnel_iface
Creates the specified interface if necessary and enters sub-command
mode. The
mode. The
no
command deletes the specified interface.
tunnel_iface
: Name of tunnel interface. tunnel([0-3]).
[no] shutdown
Deactivates the specified interface. The
no
command activates it.
tunnel source
[ipv4|tunnel_bind_interface|_any]
Configures the outer source IP address of the tunneled packets. Specify
an IPv4 address or use the IP address of an interface.
an IPv4 address or use the IP address of an interface.
_any
: Have automatically select the outer source IP. Not available for
ipv6ip mode tunnels.
tunnel destination ipv4
Configures the outer destination IP address of the tunneled IPv4 packets.
ip address ipv4 ipv4
Sets the inner source IP of packets sent through the tunnel interface.
tunnel mode ip gre
Sets this interface to use GRE tunnel mode.
[no] mtu <576..1480>
Specifies the Maximum Transmission Unit, which is the maximum number
of bytes in each packet moving through this interface. The ZyWALL
divides larger packets into smaller fragments. The
of bytes in each packet moving through this interface. The ZyWALL
divides larger packets into smaller fragments. The
no
command resets
the MTU to 1480.
[no] downstream <0..1048576>
Specifies the downstream bandwidth for the specified interface. The
no
command sets the downstream bandwidth to 1048576.
tunnel mode [ ipv6ip [ manual | 6to4
] ] ]
Sets the interface to be an IPv6 over IPv4 tunnel.
manual
: Use for a point-to-point manual tunnel for IPv6 transition. You
must also configure a policy route for the tunnel.
6to4: Use for a 6to4/6RD automatic tunnel.
ipv6 address ipv6_addr_prefix
Sets an IPv6 address with prefix for the interface.
ipv6 6to4 [ prefix ipv6_addr_prefix
| destination-prefix ipv4_cidr |
relay ipv4 ]
For a 6to4 tunnel, sets the IPv6 address with prefix, remote gateway
prefix, or relay router IPv4 address.
prefix, or relay router IPv4 address.
traffic-prioritize {tcp-ack|content-
filter|dns} bandwidth <0..1048576>
priority <1..7> [maximize-bandwidth-
usage];
Applies traffic priority when the interface sends TCP-ACK traffic, traffic for
querying the content filter, or traffic for resolving domain names. It also
sets how much bandwidth the traffic can use and can turn on maximize
bandwidth usage.
querying the content filter, or traffic for resolving domain names. It also
sets how much bandwidth the traffic can use and can turn on maximize
bandwidth usage.
traffic-prioritize {tcp-ack|content-
filter|dns} deactivate
Turns off traffic priority settings for when the interface sends the specified
type of traffic.
type of traffic.
exit
Leaves the sub-command mode.
show interface tunnel_iface
Displays the the specified tunnel’s settings.
show interface tunnel status
Displays the status of the tunnel interfaces.
