Command Remarks
1. Enter system view.
system-view N/A
2. Create a tunnel interface and
enter its view.
interface tunnel number
By default, no tunnel interface is
created.
3. Configure a description for the
interface.
description text
Optional.
By default, the description of a
tunnel interface is Tunnel number
Interface.
4. Set the MTU of the tunnel
interface.
• Set the MTU for IPv4 packets
sent over the interface:
mtu mtu-size
• Set the MTU for IPv6 packets
sent over the interface:
ipv6 mtu mtu-size
Optional.
Use either command as needed.
By default, the MTU of the tunnel
interface is 64000.
For more information about the
ipv6 mtu command, see Network
Management Command
Reference.
5. Set the intended bandwidth for the
tunnel interface.
tunnel bandwidth
bandwidth-value
Optional.
By default, the bandwidth for the
tunnel interface is 64 kbps.
6. Restore the default setting.
default Optional.
7. Shut down the tunnel interface.
shutdown
Optional.
By default, the tunnel interface is
up.
Configuring an IPv6 manual tunnel
Configuration prerequisites
Configure an IP addresses for the interface (such as a VLAN interface, Ethernet interface, or loopback
interface) to be configured as the source interface of the tunnel interface.
Configuration guidelines
Follow these guidelines when you configure an IPv6 manual tunnel:
• After a tunnel interface is deleted, all features configured on the tunnel interface are deleted.
• If the destination IPv6 network is not in the same subnet as the IPv6 address of the tunnel interface,
you must configure a static route destined for the destination IPv6 network. You can specify the local
tunnel interface as the output interface of the route or specify the IPv6 address of the peer tunnel
interface as the next hop. Alternatively, you can enable a dynamic routing protocol on both tunnel
interfaces to achieve the same purpose. For more configuration, see Network Management
Configuration Guide.
