uip-mcast6.h File Reference

This header file contains configuration directives for uIPv6 multicast support.

We currently support 2 engines:

• 'Stateless Multicast RPL Forwarding' (SMRF) RPL does group management as per the RPL docs, SMRF handles datagram forwarding
• 'Multicast Forwarding with Trickle' according to the algorithm described in the internet draft: http://tools.ietf.org/html/draft-ietf-roll-trickle-mcast
