Ok, I have what should be a fairly simple situation here, but I am unsure as to how *exactly* to do it. I have a CAT 4006, sup II engine that is presently acting only as a layer 2 switch. There is nothing fancy on it at all..... In fact, about the only configuration that was done (other than some security )to it was to set up this:
set interface sc0 1 172.16.130.192/255.255.255.0 172.16.130.255
set ip route 0.0.0.0/0.0.0.0 172.16.130.1
So it's been plodding along just fine, but now I need to make interfaces 3/1, 3/2, and 3/3 be on the 172.16.138.0/23 network. I then need to be able to get those three ports to use the same default gateway of 172.16.130.1
How do I go about doing that?
