I am waking through RFC3810 and playing with MLDv2.
From that RFC I thought when anyone send query for group
:: (all groups) and send it to address
ff02::1 all subscribers on segment should send its reports within maximum response delay. So I created and sent that query using scapy:
sendp(Ether()/IPv6(dst='ff02::1')/IPv6ExtHdrHopByHop(options=[RouterAlert()])/ICMPv6MLQuery2(mladdr="::", mrd=1000, QRV=2, QQIC=60) ,iface="USB-Eth", loop=0, inter=0)
I have win10 pc, Linux pc and Mikrotik all of them subscribed to group ff16::fe connected to same Lan (through dumb switch). I can see all of them sent correct listener report but none of those devices responds to my query. No matter if I send it from Linux or Win.
I compared my packet with some capture I found on the net and it differs only in source link local addr and check sums.
Is my expectation wrong?
