I currently have a G.8032 ring of 5170 connected to a pair of 100G packet cards in a 6500. There is also 10G packet cards connected to our core router. I created a ringed management service that goes around the ring and has an end point on the 6500 facing our core router. While I am able to see all mac-addresses from the core router and on the PKT-OTN, I am unable to ping any of them from core router. To add to this, I broke the ring to see if it was an 8032 issue, and find I cannot ping management addresses on either side of the 6500 from the other side from the nodes. So it looks like the 6500 is not passing traffic across the ring.
