Hello you all knowlegdable networkers.
We need to set up a simple routed network. We've asked our Cisco gugrus
of this configuration, and the answers are just now : 4 = it works, 4 = it
doesn't.
Could somebody with experience of this give me a hint.
We've got a class B (non standard) subnet 147.14.90.0 with 7bit host addr
and a class C addr 192.121.128.0 (8bit hostaddr today). These are connected
together with two IGS routers. Now we need to get a subnet to another city.
As we are not in need to have more than about 20-30 nodes in the C net, we'd
like to split it to 7bit host addresses and use for routing to more IGS
routers. The way we like to connect it is as followed:


network 192.121.128.0
netmask 255.255.255.128       (existing)
|-----------------------------------------------------------------------|
	|
	|
   |-----------|
   |  IGS      |
   |-----------|	
        Z        <-------- leased 64k line         
   |-----------|
   |  IGS      |
   |-----------|
        |                                         network 147.14.90.0
        |                     (existing)          netmask 255.255.255.0
|-----------------------------------------------------------------------|
                       |
                       |
                 |-----------|
                 |   IGS     |
                 |-----------|                <---   NEW
                       Z                               |
                 |-----------|                         v 
                 |   IGS     |
                 |-----------|
                       |                          network 192.121.128.128
                       |                          netmask 255.255.255.128

Routing is to be static or IGRP.
Will this work, and if it does/doesn't, why?
