Hi, we have a 2611xm and we have three subnets that pass thru it. Our problem is that we want to separate the subnet traffic so that they are "routed" thru the router and not "switched".
Currently all subnets "see" each other and we want to stop that.
FE0/0 is connected to our office and FE0/1 is connected to two other offices with a primary and secondary ip for them respectivily. I've just discovered that the 2611xm only does "inter Vlan" routing. Does anyone know that best way to stop these three subnets from seeing each other.?
The ip subnets off the 2611xm are:
Office 1: 192.168.53.0/24 via 192.168.53.240
Office 2: 192.168.40.0/30 via 192.168.40.240
Office 3: 192.168.20.0/23 via 192.168.20.230
The main reason we want to do this is that we have a RIS client (via RIS bootdisk) on Office 1 getting DHCP + scope settings from Office 3. RIS client is getting the ip address and scope settings (to find RIS Server etc..) then is failing in trying to connect to RIS server in Office 2. We think it's because all the traffic from all subnets is viewable from each different subnet and the RIS client is getting "lost" finding it's way from the 192.168.53.0 subnet to the 192.168.20.0 subnet where the RIS server is.
Any help would be appreciated.
regards
