Hello, I am trying to configure VPP for IGMP, but with this configuration it seems doesn't work:
vpp# igmp listen enable int GigabitEthernet0/3/0 > vpp# sh igmp config > vpp# trace add dpdk-input 10 > vpp# sh trace > 16:38:35:357591: dpdk-input > GigabitEthernet0/3/0 rx queue 0 > buffer 0x3666: current data 14, length 46, free-list 0, clone-count 0, > totlen-nifb 0, trace 0x0 > ext-hdr-valid > l4-cksum-computed l4-cksum-correct l2-hdr-offset 0 > PKT MBUF: port 1, nb_segs 1, pkt_len 60 > buf_len 2176, data_len 60, ol_flags 0x0, data_off 128, phys_addr > 0x928d9a00 > packet_type 0x0 l2_len 0 l3_len 0 outer_l2_len 0 outer_l3_len 0 > rss 0x0 fdir.hi 0x0 fdir.lo 0x0 > IP4: 00:50:06:00:03:00 -> 01:00:5e:00:00:16 > IGMP: 172.16.1.1 -> 224.0.0.22 > version 4, header length 24 > tos 0xc0, ttl 1, length 40, checksum 0x57e2 > fragment id 0x0000, flags DONT_FRAGMENT > 16:38:35:357630: ip4-input > IGMP: 172.16.1.1 -> 224.0.0.22 > version 4, header length 24 > tos 0xc0, ttl 1, length 40, checksum 0x57e2 > fragment id 0x0000, flags DONT_FRAGMENT > 16:38:35:357648: ip4-options > option:[0x94,0x4,0x0,0x0] > 16:38:35:357649: ip4-local > IGMP: 172.16.1.1 -> 224.0.0.22 > version 4, header length 24 > tos 0xc0, ttl 1, length 40, checksum 0x57e2 > fragment id 0x0000, flags DONT_FRAGMENT > 16:38:35:357657: igmp-input > sw_if_index 2 next-index 0 > membership_report_v3: code 0, checksum 0xeaec > 16:38:35:357660: error-drop > igmp-input: IGMP not enabled on this interface Source host: Linux a 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux, IP 172.16.1.1 Target: VPP v18.10-rc0~248-g4553c95a on VM, compiled with GCC 6.3.0 20170516, IP 172.16.1.2 Multicast group address: 224.0.0.22 As you can see, the command "sh igmp config" shows nothing, and trace is reported error: IGMP not enabled on this interface. Could you help me with this? Thanks a lot. Regards, Aleksander
