Configure NTP source ip

[ElCap]

I am running EXOS 15.7.1 on an X670-G2 and im trying to configure NTP.
the ntp server is a few hops away and the connection from the switch to next router is using a point to point /30 vlan.
when it sends an ntp request it uses the source ip of the /30 point to point vlan, but i need it to use a different self ip.
is anyway to configure what ip to use to when sending ntp requests?

...or static routes/PBR all along the path.

I have the similar situation.

I have a p2p / 30 net and mgmt network without NAT and several SVIs that are connected to the Internet(NAT). In this case, my NTP does not work, because the switch sends packets through these networks(/30 or mgmt) without NAT. Is there a simple way to configure the source IP for NTP after 3 years? (XOS 16.2.5.4 for G1 or XOS 21.1.5.2 for G2)

We are currently thinking of something similar. If I do just that, it will be redirected at the next hop back to original router and then routed again to next hop... so it has to be combined with an ACL as well, overwriting the static route in case it comes back.

Just a thought but could you set a static route in the routing table to force it out of a specific interface via next hop?
