The nexthop command allows an administrator the ability to specify a forwarding address in an iRule. The form which takes an IP address may be rejected by the validator with an error message of the form: 01070151:3: Rule [/Common/irule_example] error: Unable to find vlan, vlangroup or tunnel (10.0.0.1) referenced at line 2: [nexthop 10.0.0.1]
The iRule containing the 'nexthop IP_ADDR' command cannot be associated with a virtual server.
This occurs when the nexthop command contains only the IP address, for example: when HTTP_REQUEST { nexthop 10.0.0.1 }
The 'nexthop VLAN IP_ADDR' form of the command does pass the validator. Choose the named vlan on which IP_ADDR can be reached. For example: when HTTP_REQUEST { nexthop internal 10.0.0.1 }
Validator now allows 'nexthop IP_ADDR' in iRules.
