We have a need to have multiple IP networks recognized by an ethernet
interface on a cisco router.  Referring to the manual, cisco states
that you may have multiple secondary addresses on the ip address
subcommand line.  

We have tried this and it doesn't seem to work.  For instance,

ip address 128.196.250.1 255.255.255.0 128.196.252.1 128.196.254.1

results in no apparent change in the operation of the interace other
than changing the primary address.  A show interface command does not
show the secondary addresses, nor does the show interface command.

We must be doing something wrong.  Any ideas?
