  12. Hello you all knowlegdable networkers.
  13. We need to set up a simple routed network. We've asked our Cisco gugrus
  14. of this configuration, and the answers are just now : 4 = it works, 4 = it
  15. doesn't.
  16. Could somebody with experience of this give me a hint.
  17. We've got a class B (non standard) subnet 147.14.90.0 with 7bit host addr
  18. and a class C addr 192.121.128.0 (8bit hostaddr today). These are connected
  19. together with two IGS routers. Now we need to get a subnet to another city.
  20. As we are not in need to have more than about 20-30 nodes in the C net, we'd
  21. like to split it to 7bit host addresses and use for routing to more IGS
  22. routers. The way we like to connect it is as followed:
  23.  
  24.  
  25. network 192.121.128.0
  26. netmask 255.255.255.128       (existing)

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