Hi all, I'm sort of stumped with our PTP configuration and looking for some advice.
We're using a Microsemi TP5000 Time Server as our dedicated GM, which references GNSS for its time. It's configured to use the g8265.1 unicast profile on domain 10, and I have no issues pointing devices to it's ipv4 listening address as slaves.
Since the TP5K only supports 1000 direct clients, I'm tasked to scale this out to some of our 9Ks to act as master clocks so everything isn't pointed to the TP5K directly. Here's a basic topology:
Presently, the ASR9000 and ASR920 are direct slaves of the TP5000 and PHASE_LOCKED. However, in this case, I only want the ASR9000 peered directly with the TP5000 and distributing PTP downward to the ASR920 and other devices.
Here's what my current configuration looks like:
TP5000 - 10.99.1.1
ASR9000 - 10.88.1.1
ASR920 - 10.77.1.1
Listening on IPv4 10.99.1.1, g8265.1, domain 10
master ipv4 10.99.1.1
ipv4 address 10.88.1.1/24

How do I configure 10.88.1.1 to be a master to 10.77.1.1?
