tunnel key
<value>
Use the
tunnel key
command to specify a value shared by both endpoints of the tunnel that will provide
minimal security and differentiate between tunnels with the same source and destination addresses. Use the
no
form of this command to disable the key.
Syntax Description
<value>
Defines the key value for this tunnel (valid range: 1 to 4,294,967,294).
Default Values
By default, a key is not configured.
Functional Notes
When enabled, the key will be stored in the GRE header and the key present bit will be set. If tunnel keys
are used, a matching key value must be defined on both endpoints of the tunnel or packets will be
discarded.
Usage Examples
The following example sets the key on a tunnel interface to a value of 1234:
ProCurve(config)#
interface tunnel 1
ProCurve(config-tunnel 1)#
tunnel key 1234
