Multicast Routing Daemon v6

The Multicast Routing Daemon v6 is an IPv6 multicast routing daemon developed by Hugo Santos. Its main features include:

Extensible modular design
MLDv1 and MLDv2 support
PIM-SM support
Partial MBGP support
Supports both native and virtual interfaces
Abstract Multicast Forwarding Interface with user-space forwarding
CLI support via telnet or local access

The project is unsupported since 2013. The author states as a reason that native multicast forwarding support is available in Linux since 2005 and pim6sd could be used to manage it.
