Yes, the core switch is indeed the default router for all these
servers.

Anoop's suggestion is good, though. Whatever you find to be the router's
MAC address should have been learned by any switch in the path between
this host and the router, so it should be in the forwarding tables of
all these switches.

I believe that is the case - the MAC address for the default router
does show up in the tables of all the switches.
