[comp.protocols.appletalk] from class C to class B

jimbys@ccoroad.caltech.edu (James V. Bys) (09/27/89)

We are in the process of changing from a class C network (192.12.19)
to a class B subnetted network (131.215) with the subnet spanning the
usual 3rd byte.

We are running KIP 06/88 in a KFPS-2 with ROM revision 3.00.  

After the changeover, the KFPS acts as if it is on an unsubnetted Class B
network.  NCSA telnet 2.2 and MacIP 3.0 both can reach nodes on 131.215.139
(the KFPS's subnet) and anywhere not on 131.215

They can not reach nodes on any other subnet of 131.215

The subnet mask is set in both NCSA telnet and MacIP to FFFFFF00

The only thing slightly unusual is that during the changeover 192.12.19
and 131.215.139 are coexistent on the same ethernet cable.

The gateways on 131.215.139 are supposed to accept directed broadcasts
at 131.215.139.255

Here are the original class C files that worked, and the class B files
that don't.  Any help in tracking this problem would be appreciated!

The class B atalk.local is on the left, the class C atalk.local on the right.
