Hi all,
in our embedded device we try to get ptp running on a prp network.
When I enable prp, ifconfig looks like ...
ip netns exec process ifconfig
eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 metric 1
inet6 fe80::2d0:93ff:fe37:758e prefixlen 64 scopeid 0x20<link>

So the first question is: is it possible to use ptp in such a configuration at
all?
If so, what would be the right configuration: one ptp4l listening on both eth
devices like
ptp4l -l 5 -f /var/run/timemaster/ptp4l.0.conf -H -i eth1 -i eth2
or one ptp4l and phc2sys for each eth device?
Is there some kind of documentation describing the correct configuration of ptp
on prp?
Thank you very much in advance
Alex
