Configuration guidelines
Follow these guidelines when you configure a tunnel interface:
• When an active/standby switchover occurs or the standby card is removed on an
HSR6802/HSR6804/HSR6808 router, the tunnel interfaces configured on the active or standby
card still exist. To delete a tunnel interface, use the undo interface tunnel command.
• For an HSR6802/HSR6804/HSR6808 router, all services and traffic are processed on the service
card. Therefore, HP recommends not specifying the active card for forwarding the traffic on the
tunnel interface by using the service slot command.
• The tunnel bandwidth command sets a bandwidth value for dynamical routing protocols to
calculate the cost of the tunnel and does not affect the actual interface bandwidth. You can
determine the value according to the bandwidth of the actual output interface.
Configuration procedure
To configure a tunnel interface:
Ste
p
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. Specify the service card for
forwarding the traffic on the
tunnel interface.
• In standalone mode:
service slot slot-number
• In IRF mode:
service chassis chassis-number
slot slot-number
Optional.
Not specified by default.
If the tunnel source is a Layer 3
aggregate interface, you must
execute this command to specify
the service card for forwarding
traffic on the tunnel interface.
See the following table to view
the feature and router
compatibility.
The service command does not
take effect when a GRE tunnel
uses the SAP-4EXP interface
module for hardware forwarding
5. Set the MTU of the tunnel
interface.
• Set the MTU for IPv4 packets
sent over the interface:
mtu size
• Set the MTU for IPv6 packets
sent over the interface:
ipv6 mtu size
Optional.
