We have Cisco ASR9K running as NTP master (stratum 3) server on a loopback interface which is part of a VRF. This ASR syncs to a NTP server in global VRF. I am unable to sync any other ASR9K to this loopback IP, even when we have proper routing within VRF.
Can you guide if NTP server and client is allowed within VRF? The VRF loopbacks communicate with each other via L3 MPLS VPN.
