SROS Command Line Interface Reference Guide
tunnel destination <ip address>
Use the tunnel destination command to specify the IP address to use as the destination address for all
packets transmitted on this interface. Use the no form of this command to clear the tunnel destination
address.
Syntax Description
<ip address>
Default Values
By default, no tunnel destinations are defined.
Functional Notes
Until a tunnel interface has a destination IP address defined, it is not operational.
The tunnel destination IP address will be the value put into the destination field of the outer IP header after
GRE encapsulation of the original packet. A route must be defined for the destination address. Make
certain there are no recursive routes by ensuring that a tunnel's destination address will be routed out a
physical interface. There is a possibility of creating a routing loop when tunnel interface traffic gets routed
back to the same tunnel interface or to another tunnel interface, which in turn, does not have a route out a
physical interface. In either case, the tunnel will go down for a period of one minute, after which it will come
back up to determine whether the recursive routes have been resolved. This allows time for routing
protocols to converge on a valid route. If a static route has caused the recursive routing loop, the tunnel
status may oscillate until the route is changed.
Usage Examples
The following example sets the tunnel destination IP address to 192.168.73.101:
ProCurve(config)#interface tunnel 1
ProCurve(config-tunnel 1)#tunnel destination 192.168.73.101
5991-2114
Specifies the IP address in dotted decimal notation to use as the destination
address for all packets transmitted on this interface (for example: 192.22.73.101).
