    Is it possible to have a packets from a specific internal source override
    the router's default route?

    Here's the scenario:
    Cisco 2520 router, no BGP

    Ser0: ISP #1, high speed link, the default route unless its down , NAT using
    ISP #1 address space
    Ser1: ISP #2, low speed link, become default route if Ser0 is down, NAT
    using ISP #2 address space
    Eth0: Several web servers and 2 DNS/SMTP relay servers are attached.
    Traffic from DNS/SMTP #1 should always go out Ser0, Traffic from DNS/SMTP #2
    should always go out Ser1

    Is it possible to set up a route that routes packets based on source IP
    address so that normally only DNS/SMTP Server #2's traffic goes out that
    way?
    What does the IP ROUTE VRF command do?

    Yes, use policy routing.
