Hi community!
We have a couple of ASR 9901 with IOS XR 6.6.3 (all SP and SMUs, i hope). The ASR9k box is connected in a chain of PTP G.8275.1 and the chain is using SyncE as frequency synchronization. I my knowledge, we do have PTP and SyncE working. We have activated the interworking between PTP and NTP, but the box do not use it...it still uses a timeserver with only NTP. How can i get this to work and make ASR9k to choose PTP as best source?
