Cisco 2800 - setting both ethernet ports to 10.0.0.x - Easy Points!
Posted on 2006-05-30
Very simple question. I am consolidating two cisco routers (a 2800 and a 1720). I already configured the Serial Port on the 2800 (the 1720 is going out of production), and that works, but when I try to set the OTHER gigabitE0/1 port, to 10.0.0.4, it says that 10.0.0.0 is already in use on GigabitE0/0 (GigabitE0/0 is 10.0.0.12). Is there anyway I can assign two different IPs to the two interfaces, but have those IPs in the same subnet?
the command I use is of course in interface config:
ip address 10.0.0.4 255.255.255.0
The reason why I need this, is because the 1720 used to have E0 be 10.0.0.4 and I need to have that same IP number 'answer' on the 2800 when clients that are configured to use that IP for their default gateway need to go outside the LAN.
Thanks in advance!
