[c-nsp] bogus VPN info on cisco.com

[Robert E. Seastrom]

Yeah yeah, I know, Cisco getting it wrong in a sample config?  Oh,
that never happens, perish the thought!

But I do in fact have a need to accomplish exactly what is shown at:

http://www.cisco.com/en/US/products/sw/secursw/ps2308/products_configuration_example09186a00801c4246.shtml

Note the VPN pool is on the same subnet as Ethernet 0/1.  This means
that the router will have to respond to arps for interfaces in that
range when they are active.  It doesn't.  Tried arp blah blah blah
alias; the router responds to the arps fine then but the data doesn't
flow.

Anyone have any ideas or a similar config that they've actually gotten
to work?  I've tried a 1710 and a 2621, running 12.3 and 12.4
mainline.

Thanks,
