The higher you can get the better. You don't want to restrict your MPLS pipes unnecessarily. In case your platform counts L2 overhead into MTU leave some space for future L2 overheads (802.1ah) / label stacks (Segment Routing) and leave the rest for your customers.
See in case you'll provide carrier-ethernet services for Nick or myself we would require MTU 9100 so that we can still offer MTU 9000 to our customers in that particular region. adam _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
