Hi Hongji,

IGMP messages received via if1 will need to be transformed and sent out using if2 in your example.

The proxy needs to be configured with mPREFXI64/uPREFIX64 for its stateless address translation matters.

Cheers,
Med

Objet : some questions about IGMP-MLD Interworking Function

Hi Med,

There is  an Figure 2: IGMP-MLD Interworking in section 6.1 of RFC8114.


+----------+ IGMP    +-------+ MLD        +---------+
| IPv4     |---------| mB4   |------------| PIM     |
| Receiver |     if1 |       |if2      if3| DR      |
+----------+       | +-------+ |        | +---------+
                   |           |        |
         IGMP enable?     MLD Proxy?   MLD enable?


To implement IGMP-MLD Interworking Function, it is needed to do the following configuration. Is it right?

if1 of mB4    ---  IGMP enable ?
if2 of mB4    ---  MLD Proxy ?
if3 of PIM DR ---- MLD enable?

Dear authors,

I do think that the module should be updated to take into account the considerations discussed in:
https://tools.ietf.org/html/rfc8114#section-6.1

Thank you.

Cheers,
Med
