I have a problem with NTP on a couple of 3750 switches which are routing between VLANs.
Switch A is connected to Switch B (via a trunk port with no pruning) and both are running NTP. Both have multiple IP addresses and act as gateways to the VLANs they serve. They are running OSPF to share their routing information.
Switch A will respond to NTP requests from a machine routed by Switch B.
Switch B will respond to NTP requests from a machine routed by Switch A.
Switch A will NOT respond to NTP requests from a machine routed by Switch A.
Switch B will NOT respond to NTP requests from a machine routed by Switch B.
When I enable debugging on NTP packets. I don't even see the request from a machine the switch is responsible for routing. I do however see the requests from machines that the switch is not responsible for routing.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
