DNS redirection

Hi My existing DNS server is getting decommissoned , and moved to new server . I have few location servers which are still talkin to my old DNS server which am not aware of and i want them to communciate to my new DNS server . Can i have a VIP created in F5 with the same IP as my old DNS server and have pool created with the new DNS server so that in the event any client still contacts my old DNS the requests can be served from my DNS server

 

Please help guys

    ok, depends on your network topology but you should just be able to use a forwarding VS, see below

    "Host IP forwarding virtual server

    A host IP forwarding virtual server forwards traffic to a single destination host address. For example, the following configuration defines a host IP forwarding virtual server that accepts any traffic arriving on the Virtual Local Area Network (VLAN) named external whose destination is 10.0.0.1 on any service port using any valid TCP/IP protocol. The traffic is forwarded from the external VLAN to the destination host at 10.0.0.1:"

    ltm virtual /Common/forward_vs {
    destination /Common/10.0.0.1:0
    ip-forward
    mask 255.255.255.255
    profiles {
        /Common/fastL4 { }
    }
    source 0.0.0.0/0
    translate-address disabled
    translate-port disabled
    vlans {
        /Common/external
    }
    vlans-enabled
}
