  29 | # | Issue                                           | Jira ID  | Description                                          |
  30 +---+-------------------------------------------------+----------+------------------------------------------------------+
  31 | 1 | DHCPv4 client: Client responses to DHCPv4 OFFER | CSIT-129 | Client replies with DHCPv4 REQUEST message when      |
  32 |   | sent with different XID.                        |          | received DHCPv4 OFFER message with different (wrong) |
  33 |   |                                                 |          | XID.                                                 |
  34 +---+-------------------------------------------------+----------+------------------------------------------------------+
  35 | 2 | Softwire - MAP-E: Incorrect calculation of IPv6 | CSIT-398 | IPv6 destination address is wrongly calculated in    |
  36 |   | destination address when IPv4 prefix is 0.      |          | case that IPv4 prefix is equal to 0 and IPv6 prefix  |
  37 |   |                                                 |          | is less than 40.                                     |
  38 +---+-------------------------------------------------+----------+------------------------------------------------------+
  39 | 3 | Softwire - MAP-E: Map domain is created when    | CSIT-399 | Map domain is created in case that the sum of suffix |
  40 |   | incorrect parameters provided.                  |          | length of IPv4 prefix and PSID length is greater     |
  41 |   |                                                 |          | than EA bits length. IPv6 destination address        |
  42 |   |                                                 |          | contains bits writen with PSID over the EA-bit       |
  43 |   |                                                 |          | length when IPv4 packet is sent.                     |
  44 +---+-------------------------------------------------+----------+------------------------------------------------------+
  45 | 4 | IPv6 RA: Incorrect IPv6 destination address in  | CSIT-409 | Wrong IPv6 destination address (ff02::1) is used in  |
  46 |   | response to ICMPv6 Router Solicitation.         |          | ICMPv6 Router Advertisement packet sent as a         |
  47 |   |                                                 |          | response to received  ICMPv6 Router Solicitation     |
  48 |   |                                                 |          | packet.                                              |
  49 +---+-------------------------------------------------+----------+------------------------------------------------------+
  50 | 5 | IPFIX: IPv6_src key name reported instead of    | CSIT-402 | The report contains IPv6_src key name instead of     |
  51 |   | IPv6_dst.                                       |          | IPv6_dst when classify session is configured with    |
  52 |   |                                                 |          | IPv6 destination address. Anyhow the correct IPv6    |
  53 |   |                                                 |          | destination address is reported.                     |
  54 +---+-------------------------------------------------+----------+------------------------------------------------------+
  55 | 6 | IPv4 + VLAN: Processing of tagged frame does    | CSIT-564 | Dot1q tagged packets are thrown away in case of IPv4 |
  56 |   | not work with virtio driver.                    |          | routing on interface binded to virtio driver. Issue  |
  57 |   |                                                 |          | with VIRL test simulation environment.               |
  58 +---+-------------------------------------------------+----------+------------------------------------------------------+
  59 | 7 | Vhost-user: QEMU reconnect does not work.       | CSIT-565 | Using QEMU 2.5.0 that does not support vhost-user    |
  60 |   |                                                 |          | reconnect. It requires moving CSIT VIRL environment  |
  61 |   |                                                 |          | to QEMU 2.7.0.                                       |
  62 +---+-------------------------------------------------+----------+------------------------------------------------------+
  63 | 8 | Centos7: LISP and VXLAN sporadic test failures. | CSIT-566 | Observing sporadic crashes of DUT1 VM during LISP    |
  64 |   |                                                 |          | and VXLAN test executions, what leads to failure of  |
  65 |   |                                                 |          | all other tests in the suite. NOTE: After upgrading  |
  66 |   |                                                 |          | one of the VIRL servers host from Ubuntu14.04 to     |
  67 |   |                                                 |          | 16.04, DUT1 VM stops crashing, but tests keep        |
  68 |   |                                                 |          | failing sporadically 1-in-100. Possible root cause   |
  69 |   |                                                 |          | identified - unexpected IPv6 RA packets upsetting    |
  70 |   |                                                 |          | some test component. Currently suspecting            |
  71 |   |                                                 |          | environment or CSIT issue, but can not exclude VPP,  |
  72 |   |                                                 |          | further troubleshooting in progress.                 |
