Creating multiple subnets - Linksys RV Series

Posted on 2009-12-16

Can someone help me understand how to better use the Multiple subnets feature available on Linksys RV Series routers?

I know I can break my network in to 4 segments.  I believe I can break my network in "departmental" groups with upto 62 hosts per subnet starting at xxx.0/26, xxx.64/26, xxx.128/26 and xxx.192/26 all of which I understand to this point.  

Question is; how do I now take advantage of these multiple subnets and how are the addresses (dhcp) assigned according to the group?

    Accepted Solution

    just to clarify you want to segement 4 different networks within a /24 network right?
    DHCP address leases will take effect by pointing to the correct GW for each segement. I'm not sure about link sys RV series but in a simple network devices you can take advantage by segregating each network so one network can;t talk to the others. I would think it would be the same as using a vlan with a switch. you might want to give your network some room for growth because reconfig of this type of network might be a headache down the road.

    You could also use any of the other 192.168.X.0/24 networks so you are not restricting yourself to so few host addresses per subnet.

    Actually, I am just trying to understand this feature, I don't plan to use it just yet.  If I understand  kak1004 correctly, dhcp will issue automatically according to the designated subnet.  But how would you tell the router which device is on which subnet?  I didn't see anywhere on this router where you can define the ports and assign a subnet to them?

    Assisted Solution

    You apply the IP address for its own subnet to the VLAN and that puts that routed interface in the whole VLAN. Any PC on a port in that VLAN becomes a node in that subnet. Then you configure the router to accept and forward DHCP requests from each subnet and it puts its address as relay agent into the DHCP packets to the server so the server knows which scope to use to assign an address.

    The solution was not "complete" because the advice was not specific to the RV Series I had asked about, however, the solutions provided by both respondents did provide a better understanding of how this all would work and how to apply this feature effectively.  I would have like a more direct solution to actually configuring the RV082 router I have but I didn't actually ask for that.  So, quite happy to split the points award between two separately detailed responses.  

    Thanks to both!
