Good idea Darren,
Perhaps your way could work, the problem is that when I try to put any
IP address from the /24's in a loopback I have:
>r4(config-if)#ip address 172.16.26.1 255.255.255.0
>172.16.26.0 overlaps with Ethernet0
This sounds logical because in this case we would have two interfaces in
the same /24 network
Louie Answer could be better the problem is that I have another OSPF
Router in the same mayor network and I'm not allowed to change it.
Thanks very much for your help, but I think there is no answer.
Alejandro.
