Hi Benoit, Because of VPP's crash, I'm afraid i can't capture the pcap. But I'll share with you a packet trace of a normal interface with an IGMP packet. Normally yes, the packet goes through `ip4-lookup`, but here the path is: `ip4_input_inline`-> `ip4_input_check_x2`->`check_ver_opt_csum`. and since it has a Router Alert option, it goes to `ip4-options` then from there it goes to `ip4-local`.
In this attached pcap, `sootap-tx` is my plugin node that is registered to get IGMP packets.
igmp.pcap
Description: application/vnd.tcpdump.pcap
