defaultroute problem with multiple network interfaces

[Steve Sizemore]

We have four subnets to be managed by cfengine. Following the examples
in the documentation, my cf.main contains

    defaultroute:

        128_32_183::
            128.32.183.254

        169_229_58::
            169.229.58.1

        169_229_140::
            169.229.140.1

        169_229_248::
            169.229.248.160

and this works fine for hosts with a single NIC.

A few of our servers, however, are connected to multiple subnets,
and therefore belong to more than one of these classes - e.g.
128_32_183 and 169_229_58. On those hosts, cfagent fails -

    cf:cfengine::/var/cfengine/inputs/cf.main:134: Multiple declaration of 
variable defaultroute
    cfengine::/var/cfengine/inputs/cf.main:Redefinition of basic system variable

which makes sense, more or less. (Except that it happens even when
netconfig is not in the actionsequence.)

To fix this, I tried the following,

        128_32_183.!169_229_58::
            128.32.183.254

        169_229_58::
            169.229.58.1

However, this gives exactly the same error message.

Assigning the default route is not that important to me, but this
failure suggests a lack in my understanding of cfengine. In
particular, the fact that this happens even when netconfig is not in
the actionsequence list, is disturbing.

Can anyone help me understand what's happening and maybe fix it?
(BTW, this is cfengine-2.1.17, and the host I'm testing on is running
FreeBSD 6.0.)

Thanks.
Steve
