That is in RAs, and pertains to a prefix. Also, if a device can't use the advertised MTU, they will keep lower MTU which might be causing MTU mismatch.
For instance, if I announce 9000 as MTU and a device is bridged via wifi, wifi chips generally only supports around 2300 in MTU, so you'll have MTU mismatch with MTU blackholing within the same L2 network. This is bad.
