IP address overlapping ?

try enabling 'ip subnet zero' It should be on by default since v12.0

I am not familiar with the Boson Simulator but do I assume that the default commands that are enabled on an actual 2501 are on in the simulator such as 'ip routing' etc..? Since this is a simulator have you just for the sake of identifying whether this is a limitation of the simulator (which I doubt but never know). reconfigure the with classful addressing.. say 192.168.1.x 255.255.255.0 and 192.168.2.x

i tried, but still the same problem. Here is my config:

Rmain#show ru Building configuration...

! Version 12.1 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Rmain ! ! ! ip subnet-zero ! ! ! ! interface Serial0 ip address 223.0.0.2 255.255.255.252 no ip directed-broadcast ! interface Serial1 no ip address no ip directed-broadcast clock rate 125000 ! interface Ethernet0 no ip address no ip directed-broadcast shutdown ! interface Bri0 no ip address no ip directed-broadcast shutdown ! ! ip classless no ip http server ! ! line con 0 transport input none line aux 0 line vty 0 4 ! no scheduler allocate end

Where is the problem ?
