Using 1 DC with 2 router different ISP RRS feed

  • Question

  • Hi,

    This is my network picture:

    DC running DHCP superscope: 192.168.12.10-253 & 192.168.13.6-253

    And these are my problems which I want to:

    - All my subnets can reach each other (ex: Client: 192.169.22.100 can connect to subnet 192.168.12.x)

    - PCs of subnet 192.168.22.x to join DC and receive DHCP from this DC but only 192.168.22.x range (Off DHCP from Router ISP 2). Default gateway of these PC should be lead to ISP 2 .

    Then how should I wire it ? I really want to wire 2 switches since I don't want to use both NICs of DC :(

    My current solution is using load balance both ISP1&2 on 1st router; 2nd router wired to 1st and using routing.
    Vlan can be another solution but I'm not familiar with vlan so much.

    Can anyone help me :(

    Thank you, guys

  • Hello.

    Some questions for you that may help me understand your problem better.

    Your network diagram is not accurate because according to it there is no illustrated way for network traffic to route between the two networks. Can you provide an accurate diagram?

    Are these systems all on the same site?

    Why are you using a superscope on the DC?

    What are your network configurations on the routers?

    Stepping away from the "how do I..." stuff for a moment, what are you trying to accomplish as a business goal? Are you trying to have a redundant ISP connection in case one fails? Are you trying to segregate PCs into using different ISPs to relieve WAN congestion?

    Thanks

    Ed

  • Hi,


    I am a bit confused as well but I think what you are looking for is a static route between 192.168.22.x and 192.168.10.x  so that you have have traffic traverse the two subnets?

    If YES, then connect an Ethernet cable between the two routers 192.168.10.x and 192.168.22.x and create a static route between the two.

    I am not familiar with creating static routes on your brand router, but I did look it up and here it is:

    http://serverfault.com/questions/484874/routing-between-two-routers-with-static-routes

    BTW, you are correct in not adding a second NIC/subnet to Windows, Windows cannot load balance between two gateways, also... DHCP will not traverse the subnets.

    Why this design? It's too complex. If you want load balancing and redundancy, why not get a single router that supports load balancing two WAN? I am not sure what you are trying to accomplish here either.
