Hi folks...

This group is the best. Thanks to all who helped me with the question
below, and who help others. Collective knowledge does, indeed, exceed
the understanding of an individual.

I have a SS10 model 30 with running 4.1.3_U1 with two ethernet cards. We run
Sun Net Manager 2.2.1 to watch our very large network of servers, hubs and
routers. We have 3 Cisco routers, with the Sun station situated as shown...

                                          -------
                                         | Sun |
                                         -------
                        backbone | le0 subnet 67
                    -------------------------------------------------
                    | | |
                --------- --------- ---------
                | Cisco | | Cisco | | Cisco |
                --------- --------- ---------
                 | | | | | | | | | | | |
                 | | | | | | | | | | | |

                   hubs hubs WAN

The Sun is on the "backbone" of our network, and all the SNMP traffic is causing
much traffic and grief. What we want to do is the following....

                     subnet 25 ------- subnet 22
                     ------------------- | Sun |--------------------
                    | le0 ------- le1 |
                    | |
                    | |
                --------- subnet 67 ---------
                | Cisco |---------------------------------------| Cisco |
                --------- backbone ---------
                 | | | | | | | |
                 | | | | | | | |

                   hubs hubs

My question is this...can we use each enet interface (le0 and le1) to access
a different subnet, and if so, what do I need to change to make this so?
