I have a question about vlangroup.
안녕하세요 최근에 vlangroup을 테스트 하다가 궁금한게 생겼습니다. vlangroup을 설정하고 icmp를 통과시키고 tcpdump를 확인하면 두가지 유형으로 나옵니다. 사례 1 17:34:00.673678 6c:29:d2:a4:5b:82 > c6:f7:d5:79:71:46, ethertype 802.1Q (0x8100), length 85: vlan 11, p 0, ethertype IPv4, 10.65.154.22 > 165.244.178.4: ICMP echo request, id 19, seq 10242, length 40 in slot1/tmm0 lis= 17:34:00.673744 6e:29:d2:a4:5b:82 > c4:f7:d5:79:71:46, ethertype 802.1Q (0x8100), length 95: vlan 30, p 0, ethertype IPv4, 10.65.154.22 > 165.244.178.4: ICMP echo request, id 19, seq 10242, length 40 out slot1/tmm1 lis=_vlangroup 17:34:00.675591 c4:f7:d5:79:71:46 > 02:00:0c:07:ac:0a, ethertype 802.1Q (0x8100), length 85: vlan 30, p 0, ethertype IPv4, 165.244.178.4 > 10.65.154.22: ICMP echo reply, id 19, seq 10242, length 40 in slot1/tmm0 lis= 17:34:00.675611 c6:f7:d5:79:71:46 > 00:00:0c:07:ac:0a, ethertype 802.1Q (0x8100), length 95: vlan 11, p 0, ethertype IPv4, 165.244.178.4 > 10.65.154.22: ICMP echo reply, id 19, seq 10242, length 40 out slot1/tmm1 lis=_vlangroup Case 2 If you look at the sequence number, there are 4 packets generated for each pass, sometimes only 2 vlangroups pass through at the end and sometimes all 4. What is the difference between the two? thank you
