Hi, From the man page for bridge (4): If an IP packet is too large for the outgoing interface, the bridge will perform IP fragmentation. This can happen when bridge members have different MTUs or when IP fragments are reassembled by pf. Non-IP packets which are too large for the outgoing interface will be dropped.
Is it somehow possible (maybe with different features?) to fragment a layer2 frame for reassembly on the other side of a bridge? This would be for use with MPLS, so using pf's scrub directive would not be applicable. The desired behavior would be to take in 1500 bytes of IP payload with an added MPLS label and transport this inside a gif/ipsec tunnel over the internet (with a wan-link MTU of 1500). --Doug
