> The problem is, how’d the packet get so big that it was fragmented? HNCP relies on network-layer fragmentation: it uses UDP and has no application-layer mechanism for fragmenting large TLVs. See Section 4.2 and Appendix B.2 of RFC 7787.
(I seem to recall that an earlier version of DNCP included provisions for application-layer fragmentation of TLVs, but that was removed at some point. I don't remember why.) Let's please come back to my question. RFC 4443 paragraph 3.2 says A Packet Too Big MUST be sent by a router in response to a packet that it cannot forward because the packet is larger than the MTU of the outgoing link. If your tunnelling software violates this, how is it not buggy? -- Juliusz _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
