Bug Description
Seen in r3.1-87 mitaka, icmp pkts were not sent to the analyzer vm when mirroring was configured. (logs uploaded to /cs-shared/bugs/)
- contrail-ha cluster with 2 computes (server4 and server5)
- src compute server4 -> dst compute server5 => analyzer compute server5
- Created 3 VNs ctest-vn1-
- Attached policy ctest-vn1_
- Attached policy ctest-vn1_
- Attached policy ctest-vn2_
- created VM ctest-src_
- created VM ctest-analyzer_
- tap interface default-
- Validated routes of VM ctest-dst_
- tap interface default-
- tap interface default-
- Compute/VM: SRC: server4 / 186.232.40.3, -> DST: server5 / 82.247.190.3 => ANALYZER: server5 / 4.72.227.3
- Started tcpdump to capture the mirrored packets.
- Ping to IP 82.247.190.3 from VM ctest-src_
- Ping from 186.232.40.3 to 82.247.190.3 executed with c=5, expected mirrored packets 5 Ingress,5 Egress count = 10
- Waited for the tcpdump write to complete but no ICMP packets mirrored to the analyzer VM ctest-analyzer_
