Where is this routing to?

Hey, all. I'm trying to trace out the route on one of my networks and it is hitting a Big IP that is configured quite differently than any of the other Big IPs I use. Typically when something gets routed through my Big IP I take the self IP, navigate to the correct partition, review the routing table, and take whatever route is listed... Easy.

On this Big IP under the Self IP section I see (IPs changed, but all other information is the same) (I left out the "application" field as it is empty):

Name      IP Address    Netmask            VLAN / Tunnel    Traffic Group              Partition / Path
10.1.1.1  10.1.1.1      255.255.255.0      prod100          traffic-group-local-only   Common

I then go to the Routes section and look under the "Common" partition and see ("netmask" field removed as it was empty):

Name                   Destination     Route Domain    Resource Type     Resource       Partition / Path
default_prod_200       Default IPv4    3               Gateway           10.15.1.1%3    Common
default_trans_202_203  Default IPv4    1               Gateway           10.15.2.1%1    Common
default_trans_204_205  Default IPv4    1               Gateway           10.15.3.1%2    Common

Which route is this going to be taking? How can I confirm? Are there any CLI commands that would make determining the route easier than my current method of navigating the multiple screens of the GUI?

Thanks.
