I was able to figure out the routing issue by adding the sub net instead of the IP for the next hop. However I am still unable to get the transparent clock working.
on the GM side I am using the followings ptp4l -P -i enp25s0f0 -f GM.cfg with GM.cfg being [global] dataset_comparison G.8275.x priority1 201 priority2 200 G.8275.defaultDS.localPriority 128 masterOnly 1 G.8275.portDS.localPriority 128 hybrid_e2e 0 inhibit_multicast_service 1 unicast_listen 1 unicast_req_duration 60 announceReceiptTimeout 20 delay_mechanism P2P [unicast_master_table] table_id 1 logQueryInterval 2 UDPv4 192.168.2.100 # [enp25s0f0] unicast_master_table 1 on the OC I have ptp4l -P -i enp25s0f0 -f OC.cfg -s -m with OC.cfg being [global] dataset_comparison G.8275.x G.8275.defaultDS.localPriority 128 priority1 221 priority2 220 masterOnly 0 G.8275.portDS.localPriority 128 hybrid_e2e 1 inhibit_multicast_service 1 unicast_listen 1 unicast_req_duration 60 announceReceiptTimeout 10 delay_mechanism P2P [unicast_master_table] table_id 1 logQueryInterval 2 UDPv4 192.168.2.100 [enp25s0f0] unicast_master_table 1 and on the TC (the node in the middle connecting GM to OC) ptp4l -i enp25s0f0 -i enp25s0f1 -s -f P2P-TC.cfg -m with P2P-TC.cfg being [global] priority1 254 free_running 1 freq_est_interval 3 tc_spanning_tree 1 summary_interval 1 clock_type P2P_TC network_transport L2 delay_mechanism P2P tx_timestamp_timeout 50000 My observation is, the OC works and syncs with the GM the moment I start the TC code but with high error (less than of 100us).
