Command Remarks
3. (Optional.) Configure a description
for the interface.
description text
By default, the description of a
tunnel interface is Tunnel
number Interface.
4. (Optional.) Specify a service card for
forwarding the traffic on the tunnel
interface (MSR4000).
service slot slot-number
By default, no service card is
specified.
5. Set the MTU of the tunnel interface.
mtu mtu-size
By default, the MTU is 64000
bytes.
6. Set the expected bandwidth for the
tunnel interface.
bandwidth bandwidth-value
By default, the expected
bandwidth is 64 kbps.
The expected bandwidth for the
tunnel interface affects the link
cost value. For more
information, see Layer 3—IP
Routing Configuration Guide.
7. Set the ToS for tunneled packets.
tunnel tos tos-value
The default setting is the same
as the ToS of the original
packet.
8. Set the TTL for tunneled packets.
tunnel ttl ttl-value
The default TTL for tunneled
packets is 255.
9. Set the VPN to which the tunnel
destination belongs.
tunnel vpn-instance
vpn-instance-name
By default, the tunnel
destination belongs to the
public network.
To set the VPN for the tunnel
source, use the ip binding
vpn-instance command. The
tunnel source and destination
must belong to the same VPN.
Otherwise, the tunnel interface
cannot go up.
10. (Optional.) Restore the default
settings of the tunnel interface.
default N/A
11. (Optional.) Shut down the tunnel
interface.
shutdown
By default, the tunnel interface
is up.
Configuring an IPv6 over IPv4 manual tunnel
Follow these guidelines when you configure an IPv6 over IPv4 manual tunnel:
• The tunnel destination address specified on the local device must be identical with the tunnel source
address specified on the tunnel peer device.
• Do not specify the same tunnel source and destination addresses for the tunnels in the same mode
on a device.
• To ensure correct packet forwarding, identify whether the destination IPv6 network and the IPv6
address of the local tunnel interface are on the same subnet. If not, configure a route reaching the
destination IPv6 network through the tunnel interface. You can configure the route by using one of
the following methods:
