This is very poor reason to kill it for everyone, 'I recall I may have found platform where it maybe didn't work'. Yet, it's super common go have L3Termination - L2Aggregation - Customer. And sell various MTU options to customers, even use the L2Aggregation as core between two L3Termination. All of these require per logical-interface L3 MTU, while L2 MTU is usually set to max. >From Cisco, I've done this at least on 720x, 7301, 7304 NPE/NSE, 7600, 6500, GSR, CRS-1, ASR1k, ASR9k, 2600, 3600, ASR9k, probably some others too. -- ++ytti
