Configure NTP source ip

Configure NTP source ip

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?

Thanks for your quick reply!

I can't do that: The provider is blocking traffic from that IP, as it's for BGP transit only.

Will let you know when (if) I have a solution...

i didnt find a way... i ended up using the p2p ip and had to get the ntp server to allow it.

Exactly my problem as well - is there a way to change the source ip-address, e.g. via ACL?

Hi,

There isn't a feature to specify the source VLAN to carry the NTP request.
