no sure what version you run on - just had a bad fall with ccr trying to bond to cisco switch. cisco lacp channel falls over after 30 seconds complaining about miss configuration of ethernet interfaces - not port channels - looks like low level packet scrambling/loop at ethernet interface on CCR. All works fine on a RB750G 6.10 - so just have to wait what MT will pick up over time to fix it. sadly, my ccr1016 is in production so really stuck with further testing - though might have to get one to open support tickets.
I have moved it to balanced and turn the ports on switch to port-channel (not lacp).
Do I need to do that ?
I get the feeling I don’t
when i check my /interface print output there are 2 mac’s on the SPF+ interfaces, I thought it was meant to write the same on both !
