In Juniper, NTP broadcast is set at system level, so two VRFs cannot use the same addressing and use NTP broadcast at the same time. Is there any alternative?

    Do you have a specific use case that requires NTP in broadcast mode? The best alternative may be to not use ntp broadcast.

I know that most of the type the same configuration you want in the default instance exists in the same config stanza within routing-instances, in this case it's the other way around.

Addressing shouldn't matter as routing instances are separate routing tables.

You can enable broadcast NTP in a VRF with:

set system ntp broadcast routing-instance-name VRFA
set system ntp broadcast routing-instance-name VRFB
set system ntp broadcast routing-instance-name VRFC
