HP 7000 dl Router manual Tunnel destination ip address

Command Reference Guide Tunnel Configuration Command Set

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>	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).

Default Values

By default, no tunnel destinations are defined.

Command Modes

(config-tunnel x)# Tunnel Interface Configuration Mode

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. Be 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 if 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 192.22.73.101:

(config)#interface tunnel 1

(config-tunnel 1)#tunnel destination 192.22.73.101
