Hello everyone,

I am pleased to announce the public release of pimbd, the PIM implementation 
that was demonstrated during the last Bits and Bites in Prague.

https://github.com/Oryon/pimbd <https://github.com/Oryon/pimbd>

It is a compliant IPv6 PIM-BIDIR implementation which also does:
- IPv4 multicast routing in a non-compliant way by including IPv4 groups in 
IPv6 Join/Prunes (Because it works although it is forbidden by the specs). It 
is obviously disabled if you don’t enable IGMPv3 listener.
- Implements the PIM-SSBIDIR extensions: 
https://tools.ietf.org/html/draft-pfister-pim-ssbidir-00 
<https://tools.ietf.org/html/draft-pfister-pim-ssbidir-00>
- Implements the PIM border proxy extensions: 
https://tools.ietf.org/html/draft-pfister-pim-border-proxy-00 
<https://tools.ietf.org/html/draft-pfister-pim-border-proxy-00>
- Can be configured by HNCP in order to function without any human 
configuration: https://tools.ietf.org/html/draft-pfister-homenet-multicast-00 
<https://tools.ietf.org/html/draft-pfister-homenet-multicast-00>

It runs on any Linux (given it has the required multicast routing support).
An OpenWrt package has been published in the routing feed: 
https://github.com/openwrt-routing/packages 
<https://github.com/openwrt-routing/packages>.

As stated above, pimbd can be configured by HNCP, and will if you install both 
pimbd and hnetd (https://github.com/sbyx/hnetd <https://github.com/sbyx/hnetd>) 
packages on your OpenWrt router.

You will notice that the three above drafts have expired.
I have no intention to revive them unless there is a strong support from the 
homenet working group to keep moving this way. I do believe that a routed home 
network will need routed multicast to work ‘somehow’. One of the purpose of 
this implementation was to provide a possibly-temporary patch to this missing 
part in our homenet implementation. At least, now, we can route multicast ! As 
for the IETF work, BIER based solutions might be interesting to consider.

Thanks to all those who contributed.

Pull requests are welcome.

Have a nice day,

- Pierre
