  Looks like you've got a routing loop, so you're probably running a routing protocol such as RIP, EIGRP, OSPF, etc ?  A loop could be caused by an interface or router going up & down often, misconfigured routes, etc.  
   Check the routing tables & configs on your routers & layer-3 switches (if present), check for downed links or "flapping" links, ie an interface that persistently keeps going up/down, duplex mismatches on interfaces, etc.

Or there is no route configured for's network on your router. your router passes your ping request to its default gateway, and there it gets lost.

that sounds to me like a more possible reason..
