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?
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 10.1.0.0 routing-instance-name VRFA set system ntp broadcast 10.2.0.0 routing-instance-name VRFB set system ntp broadcast 10.3.0.0 routing-instance-name VRFC
