Hello Jeroen, Thanks for the feedback. If you can find the bug IDs, please do not hesitate to send them, it come in handy sometimes.
I have been thinking of upgrading to SXI3 (why not SXI4, hey ;-) for a long time and have labed it, all my configs were correctly accepted. We are running some basic BGP / MPLS and route reflection on this router, have experienced any weird things regarding theese on SXI3 / SXI4 ? Thanks again. Best regards.
