In my IP6 implementation I did not do anything with the
mld_mac_filter parameter. It is just set to null in netif_add. FF02::1
is the all nodes multicast group so I think by default you are already
joined to that group.
The only thing I can think of that you haven't mentioned is to make
sure your MAC is set up to accept multicast packets. It may be set to
receive broadcast already but IP6 won't work if it is not set to
receive multicast.

Subject: [lwip-users] IPv6 porting, need help in netif->mld_mac_filter
Hi,
I am new to LWIP IPv6 implementation.
I am trying to port it for my device, I have set below netif param
and #define to respective values
#define LWIP_IPV6 1
#define LWIP_IPV6_DHCP6 1
#define LWIP_ICMP6 1
#define LWIP_IPV6_AUTOCONFIG 1
#define LWIP_IPV6_NUM_ADDRESSES 6
netif->ip6_autoconfig_enabled = 1;
netif->output_ip6 = ethip6_output;
With this setting I could see LWIP is sending
a> "Multicast Listner Report"
b> Neighbour solicitation
c> Router Solicitation (to ff02::2)
Also I can see my router is sending me Router advertisement (to
ff02::1) which I am not able to receive. I feel this is because I
haven't set below parameter in netif
netif->mld_mac_filter = ?????;
I am not sure what this function should be, As I know I have to join
this multicast group to receive the advertisement packet.
Can someone help me in what this function should point to and is some
example already available?
Thanks and Regards,
Manoj
