Well, we try to be fully 4861-compliant on the backbone. The backbone is supposed to be an Ethernet or a similar high-capacity link, so it should have little problem with that load. > Why cluttering the backbone? Because that's what 4861 does to you? :-) Of course, the ERs could speak a different protocol between themselves, but the idea was to enable other nodes to live on the backbone link and communicate with the 6lowpan nodes without requiring any 6lowpan-specific code. Those other nodes will speak 4861 only. Gruesse, Carsten _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
