Configuration Tasks
interface tunnel
tunnel checksum
240
To configure an IP tunnel:
Create or select a physical or loopback interface.
1.
This interface acts as an anchor for the source of the tunnel.
Assign an IP address to the physical or loopback interface.
2.
Create a tunnel interface.
3.
Set the source address for the tunnel.
4.
Set the destination address for the tunnel.
5.
(Optional) Enable error checking across a GRE tunnel.
6.
Set the maximum transmission unit (MTU) size for the tunnel.
7.
NOTE: On SM interfaces, issue only the commands listed below. Do not configure
protocols such as Multilink PPP or Multilink Frame Relay on SM interfaces.
Use to create an IP tunnel interface.
Specify the type and name of the tunnel you want to create.
You can use the transport-virtual-router keyword to establish the tunnel on a virtual
router other than the current virtual router.
Example
host1(config)#interface tunnel dvmrp:boston-tunnel-1 transport-virtual-router boston
Use the no version to remove the tunnel.
NOTE: When you delete a virtual router that has been configured as a transport virtual
router for a DVMRP tunnel, the show configuration output displays No Router for the
transport virtual router. To remove the DVMRP tunnel interface, simply omit any
reference to the transport virtual router. For example, to delete interface tunnel
dvmrp:boston-tunnel-1 transport-virtual-router No Router from the configuration,
issue the command, no interface tunnel dvmrp:boston-tunnel-1.
See interface tunnel.
Use to enable checksum computation across a GRE tunnel.
Checksum computation is not supported for DVMRP tunnels.
