Step Command Remarks By default, no tunnel interface is created. When you create a new tunnel 2. Create a tunnel interface, specify the tunnel mode, and enter tunnel interface view. interface tunnel number mode { gre [ ipv6 ] | ipv4-ipv4 | ipv6 | ipv6-ipv4 [ 6to4 | isatap ] } interface, you must specify the tunnel mode. When you enter the view of an existing tunnel interface, you do not need to specify the tunnel mode. The two ends of a tunnel must use the same tunnel mode. Otherwise, packet tunneling will fail. 3. (Optional.) Configure a description for the interface. description text 4. (Optional.) Specify an IRF member device for forwarding the service slot slot-number traffic on the interface. By default, the description of a tunnel interface is Tunnel number Interface. By default, no IRF member device is specified. 5. Set the MTU of the tunnel interface. mtu mtu-size By default, the MTU is 64000 bytes. Set an appropriate MTU to avoid fragmentation. The MTU for the tunnel interface applies only to unicast packets. An MTU set on any tunnel interface is effective on all existing tunnel interfaces. 6. Set the bandwidth for the tunnel interface. tunnel bandwidth bandwidth-value The default setting is 64 kbps. This command sets a bandwidth for dynamical routing protocols to calculate the cost of the tunnel and does not affect the actual interface bandwidth. You can set the value according to the bandwidth of the egress interface. 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. 9. (Optional.) Restore the default settings of the tunnel interface. tunnel ttl ttl-value default The default TTL for tunneled packets is 255. N/A 10. (Optional.) Shut down the tunnel interface. shutdown By default, a tunnel interface is in UP state.
