Would you want a different DF for v4 and v6 devices? Maybe no -- because this is layer 2 forwarding, but maybe yes. If the answer is no, then this should be documented, I think, even if it's in a different doc. :-) Russ _______________________________________________ BESS mailing list [email protected] https://www.ietf.org/mailman/listinfo/bess
