I have two CCR1036-12G-4S in production use with ROS v6.25 on each. SFP4 of the first router and SPF1 of the second router is connected to a fiber E-LINE between the two. I am able to pass all traffic normally except that the two CCR1036-12G-4S routers cannot ping each other. The first CCR1036-12G-4S has ports ETH1-ETH12, SPF3, and SPF4 bridged and an IP of 100.64.0.1/10 on the bridge interface. The second CCR1036-12G-4S has ALL ports bridged with an IP of 100.64.0.2/10 on the bridge interface. Is this a bug or am I missing something?

OK I know why its not working now but I'm at a loss as to why its like this. both of the CR1036-12G-4S routers have the same MAC addresses on the ports. Shouldn't the MAC addresses be different between devices? Why would this be like this?

You must have made a backup on one and restored that backup on the other.

Do an '/interface ethernet reset-mac-address [find]' on both, and the one whose MACs have been changed will revert back to factory addresses.

Thank you for the response. I did figure out to reset them. I've been meaning to post back on this for a bit. I would love to see a feature added to ROS to allow the ability to choose whether to use the old devices MAC addresses or just accept the MAC addresses of the new device. Unless there is way to do this already somehow. I can understand there would be reasons to keep the preexisting MAC addresses but I would have never expected this normally. I'll have to add that bit of knowledge to my memory banks. I'm sure I'll run into it again.
