Bridging different MTU networks

« on: October 06, 2020, 05:13:24 pm »

It it ok to bridge different local subnets from different switches that have different MTU's?
I assume OPNsense would handle the fragmentation internally, but maybe not.

Please advise.

Fragmentation can only occur at layer 3, e.g. routing.

So does that mean I shouldn't bridge different MTU networks?
