3、Routing

3.1 启动虚机

——host1

在前面的练习中，已经启动该虚机。如果没有启动，执行：

virsh start host1

添加网关配置：

$ sudo ip route add default via 10.100.0.254 dev eth0
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000link/ether 52:54:00:3f:15:ea brd ff:ff:ff:ff:ff:ffinet 10.100.0.10/24 scope global eth0valid_lft forever preferred_lft foreverinet6 fe80::5054:ff:fe3f:15ea/64 scope link valid_lft forever preferred_lft forever
$ ip route
default via 10.100.0.254 dev eth0 
10.100.0.0/24 dev eth0  src 10.100.0.10 
$

——host2

在前面的练习中，已经启动该虚机。如果没有启动，执行：

virsh start host2

添加网关配置：

$ ip route
default via 10.100.0.254 dev eth0 
10.100.0.0/24 dev eth0  src 10.100.0.20 
$ 
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000link/ether 52:54:00:3e:93:2d brd ff:ff:ff:ff:ff:ffinet 10.100.0.20/24 scope global eth0valid_lft forever preferred_lft foreverinet6 fe80::5054:ff:fe3e:932d/64 scope link valid_lft forever preferred_lft forever
$ ip route
default via 10.100.0.254 dev eth0 
10.100.0.0/24 dev eth0  src 10.100.0.20 
$

 ——host3

在前面的练习中，已经完成host3的配置。host3是首次启动：

root@server1:~# virsh start host3
Domain 'host3' started

配置IP地址和网关：

root@server1:~# virsh console host3
Connected to domain 'host3'
Escape character is ^] (Ctrl + ])login as 'cirros' user. default password: 'gocubsgo'. use 'sudo' for root.
cirros login: cirros
Password: 
$ 
$ sudo ip addr add 10.200.0.10/24 dev eth0
$ sudo ip route add default via 10.200.0.254 dev eth0
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host valid_lft forever preferred_lft forever

$ ip route
default via 10.200.0.254 dev eth0 
10.200.0.0/24 dev eth0  src 10.200.0.10

3.2 设置日志

——设置 vconn 模块的日志级别为 dbg

为了查看流表下发情况，设置 vconn 模块的日志级别为 dbg：

ovs-appctl -t ovs-vswitchd vlog/set vconn:fIle:dbg

查看是否修改成功：

ovs-appctl -t ovs-vswitchd vlog/list

root@server1:~# ovs-appctl -t ovs-vswitchd vlog/set vconn:fIle:dbgroot@server1:~# ovs-appctl -t ovs-vswitchd vlog/listconsole    syslog    file-------    ------    ------
backtrace          OFF        ERR       INFO

...
vconn              OFF        ERR        DBG

——开启实时日志

faucet.log：

root@server1:~/faucet/inst# tail -f faucet.log

ovs-vswitchd.log： 

root@server1:/var/log/openvswitch# tail -f ovs-vswitchd.log | grep -v -e "OFPT_ECHO_REQUEST" -e "OFPT_ECHO_REPLY"

  3.3 编辑控制器yaml文件

dps:switch-1:dp_id: 0x1timeout: 8000arp_neighbor_timeout: 3600interfaces:1:native_vlan: 1002:native_vlan: 1003:native_vlan: 1004:native_vlan: 2005:native_vlan: 200

3.4 重启faucet

docker restart faucet

root@server1:~/faucet/inst# docker restart faucet
faucet

这段日志记录了 sw1 交换机与位于 127.0.0.1:6653 的 OpenFlow 控制器之间的一次完整连接与流表下发过程。以下是关键行为及其含义逐步解析：

✅ 连接建立过程

  1. connection closed by peer
    控制器主动断开了连接。

  2. connecting... → sent OFPT_HELLO → received OFPT_HELLO
    双方开始新的 OpenFlow 握手，协商版本成功为 OpenFlow 1.3（0x04）。

  3. connected
    握手完成，连接建立成功。

✅ 基本能力交换

  1. 控制器下发了 OFPT_FEATURES_REQUEST，交换机回应其 DPID 及能力（支持 flow/table/port/group/queue stats 等）。

  2. 控制器请求端口信息 OFPST_PORT_DESC，OVS 返回所有端口状态，包括 sw1p1~sw1p5。

✅ 控制器配置行为

  1. 控制器设置异步消息策略 SET_ASYNC 和配置帧 SET_CONFIG。

    • 初始设置所有异步消息类型为关闭（off），之后更新为开启部分消息（如 PORT_STATUS, PACKET_IN）。

✅ 流表下发分析（共45条 ADD，2条 DEL）

这是控制器对交换机下发的一套完整 pipeline，流表涵盖多个表（table 1~5），每条匹配条件清晰、优先级明确定义。

流表设计概览：

表号用途简述
table:0设置入口vlan
table:1入端口/入 VLAN 处理，分发到后续表
table:2路由处理，根据 VLAN 和 IP dst 决定走向
table:3控制类包（ARP、ICMP）交由控制器处理或进入下一表
table:4二层转发
table:5L2 广播、组播、未知单播处理等出口逻辑

部分重点流项解释：

  • VLAN打标签处理（从物理口进入无 VLAN 的报文）：

    ADD priority=4096,in_port=1,vlan_tci=0x0000/0x1fff actions=push_vlan,set_field:4196->vlan_vid,goto_table:1

    表示从 sw1p1（port=1）进入的裸包将打上 VLAN 100（0x100 + 100 = 4196），然后跳转到 table 1。

  • L2 广播处理：

    table:5, dl_vlan=100, dl_dst=ff:ff:ff:ff:ff:ff actions=pop_vlan,output:1,2,3

    表示 VLAN 100 内的广播包去往对应端口。

  • ARP、ICMP、IP 控制包处理：
    table:3 中匹配对应类型后送至 CONTROLLER:64 表示发给控制器处理。

  • drop 规则：
    每个表尾都有一条优先级为 0 的 actions=drop 规则，作为默认匹配兜底。

🔄 连接恢复过程小结

连接断开→重连→成功握手→控制器重新同步流表，这整个过程说明：

  • 控制器具有“状态恢复”能力。

  • OVS 与控制器兼容良好，使用的是 OpenFlow 1.3（非常主流版本）。

  • 所有行为正常，没有明显错误。

✅ 总结诊断结论

  1. 连接和握手状态良好。

  2. 控制器主动下发了详细完整的流表管线配置，逻辑严密。

  3. 流表功能涵盖 VLAN 入端口处理、L2 广播组播控制、L3 控制包引导等，是典型的多表 pipeline 架构。

  4. 若你遇到“控制器掉线”、“ovs-vswitchd 不执行规则”等情况，这里看起来都没有异常。

  5. 如果你是为了调试 diff-flows 等问题，这时控制器已经更新了整个 flow 状态，应该作为基准。

     这种行为 非常典型地说明控制器在首次收到 ICMP 流量时触发了 Packet-In，然后下发 FlowMod 建立流表。由于这个过程有少许延迟，第一个 Echo Request 没来得及完成匹配和转发，所以丢了。

    后续包则走了 datapath 缓存（megaflow / fastpath），转发流畅，不再需要交互控制器。

    这是 预期中的正常行为，并不是配置错误。OpenFlow 控制器收到第一包 packet-in 后来不及下发规则，导致第一个包掉。后续因流表下发成功，通信恢复正常。

    非常好，这段 Faucet 日志和你前面的抓包、OVS 日志一起，已经完整验证了首次 Ping 丢包（25%）是“正常的首次流表学习行为”，没有任何异常。

    Faucet 控制器从 OVS 收到了 packet-in：

    这段 ovs-vswitchd 日志清晰地展示了 一个典型的基于 SDN 控制器的 ARP 学习 + 流表下发 + 流量处理的完整闭环。我们来逐步还原这段过程发生了什么。

    🧠 网络场景概述（推测）

    你模拟了两个 VLAN 网络（100 和 200）之间的通信：

    • 10.100.0.10（VLAN 100） → ping → 10.200.0.10（VLAN 200）

    • MAC 地址和端口：

      • 52:54:00:3f:15:ea 绑定 10.100.0.10（in_port=1）

      • 52:54:00:29:ef:e9 绑定 10.200.0.10（in_port=4）

      • 控制器 MAC 是 0e:00:00:00:00:01

    🧾 关键事件流程还原

    1️⃣ 10.100.0.10 发 ARP 请求（查 10.100.0.254）

    2025-06-22T13:01:37.782Z|03629|vconn|DBG|tcp:127.0.0.1:6653: sent (Success): OFPT_PACKET_IN (OF1.3) (xid=0x0): table_id=3 cookie=0x5adc15c0 total_len=46 in_port=1 (via action) data_len=46 (unbuffered)
arp,dl_vlan=100,dl_vlan_pcp=0,vlan_tci1=0x0000,dl_src=52:54:00:3f:15:ea,dl_dst=ff:ff:ff:ff:ff:ff,arp_spa=10.100.0.10,arp_tpa=10.100.0.254,arp_op=1,arp_sha=52:54:00:3f:15:ea,arp_tha=00:00:00:00:00:00

    控制器收到后回应：

    2025-06-22T13:01:37.793Z|03634|vconn|DBG|tcp:127.0.0.1:6653: received: OFPT_PACKET_OUT (OF1.3) (xid=0x23dc1560): in_port=CONTROLLER actions=output:1 data_len=60
arp,vlan_tci=0x0000,dl_src=0e:00:00:00:00:01,dl_dst=52:54:00:3f:15:ea,arp_spa=10.100.0.254,arp_tpa=10.100.0.10,arp_op=2,arp_sha=0e:00:00:00:00:01,arp_tha=52:54:00:3f:15:ea

    并顺势下发一组流表（说明控制器做了 learning）：

    • table 4：VLAN100 → MAC 52:54:00:3f:15:ea 的 output:1 规则

    • table 2：匹配 nw_dst=10.100.0.10，准备发给该主机（从两条 VLAN：100/200 来）

    • table 1：从 in_port=1 学到该主机属于 VLAN100，goto_table:4

    2️⃣ 10.100.0.10 发 ping 到 10.200.0.10

    2025-06-22T13:01:37.794Z|03635|vconn|DBG|tcp:127.0.0.1:6653: sent (Success): OFPT_PACKET_IN (OF1.3) (xid=0x0): table_id=3 cookie=0x5adc15c0 total_len=102 in_port=1 (via action) data_len=102 (unbuffered)
icmp,dl_vlan=100,dl_vlan_pcp=0,vlan_tci1=0x0000,dl_src=52:54:00:3f:15:ea,dl_dst=0e:00:00:00:00:01,nw_src=10.100.0.10,nw_dst=10.200.0.10,nw_tos=0,nw_ecn=0,nw_ttl=64,nw_frag=no,icmp_type=8,icmp_code=0 icmp_csum:85a7

    这时控制器还没学到目标主机 10.200.0.10，所以先下发两条 drop 流表

    2025-06-22T13:01:37.796Z|03636|vconn|DBG|tcp:127.0.0.1:6653: received: OFPT_FLOW_MOD (OF1.3) (xid=0x23dc1561): ADD table:2 priority=12320,ip,dl_vlan=200,nw_dst=10.200.0.10 cookie:0x5adc15c0 hard:668 out_port:0 actions=drop

    同时控制器开始广播ARP 请求找目标主机：

    控制器回复 ARP：

    2025-06-22T13:01:43.787Z|03647|vconn|DBG|tcp:127.0.0.1:6653: received: OFPT_PACKET_OUT (OF1.3) (xid=0x23dc1568): in_port=CONTROLLER actions=output:4 data_len=60

    并补充完整流表：

    • table 4: VLAN200 → MAC 52:54:00:29:ef:e9 → output:4

    • table 2: nw_dst=10.200.0.10 → 修改 VLAN + MAC + goto table 4

    • table 1: in_port=4 → MAC 学习流

    ✅ 总结判断

    这一段日志里，控制器完成了以下事情：

    操作说明
    接收 ARP 和 ICMP 的 packet-in来自 sw1p1（port 1） 和 sw1p4（port 4）
    发出 ARP reply 和广播使用 OFPT_PACKET_OUT
    下发精细的流表3 张表联合处理，完成 VLAN 切换和地址重写
    处理 ICMP 前的防御性 drop控制器还没掌握 MAC 前，先下发 drop，避免意外转发

    📌 你可以从这看出：

    1. vconn 日志非常适合跟踪 OpenFlow 控制器收发细节；

    2. 控制器的行为是符合逻辑的，按照 packet-in → ARP 学习 → flow_mod 下发 → packet-out → data plane 安静的流程推进；

    3. 每条 packet-in 都对应控制器响应措施，有“实效性”强的控制器在后台逻辑起作用。

    ✅ 表结构设计分析（table 1 → 2 → 4）

    表职责分配逻辑推测如下：

    表匹配字段作用
    Table 1in_port + dl_vlan + dl_src做MAC 学习，将入口端口与源MAC、VLAN绑定，用于 host tracking
    Table 2dl_vlan + nw_dst做三层转发决策（IP 目的地址），并设置 VLAN、MAC（做出方向逻辑）
    Table 4dl_vlan + dl_dst做二层转发出接口匹配，并 pop VLAN，最终转发出去
    这种分表结构非常常见于 Faucet/SONiC/ONOS 等控制器生成的流表：
    Table 1 负责 host 学习 → Table 2 负责三层处理 → Table 4 作为出接口查找。

    这两条是 路由转发（L3 forwarding）相关的 megaflow，表现出 Faucet 已成功为两个 VLAN 之间下发了路由规则。 

    ✅ 说明：Faucet 实现了典型的 Router-on-a-stick 模式

    这就是 Faucet IPv4 路由模式的正常表现：

    • 每个 VLAN 配置了一个虚拟 IP（VIP）：

      • 10.100.0.254/24 on VLAN 100

      • 10.200.0.254/24 on VLAN 200

    • Faucet 在 datapath 层下发转发表，实现不同 VLAN 之间的路由

    • 流量进入一个 VLAN，匹配目的 IP 后：

      • 修改 MAC 地址

      • TTL 减一

      • 输出到另一个端口

    3.5.2 匹配流表分析

    host1 ping host3，host1和host3处于不同网段。

    host1首先需发出arp请求，请求解析网关10.100.0.254的mac。此时匹配流表（完整流表flows-1）：

    • priority=4096,in_port=sw1p1,vlan_tci=0x0000/0x1fff actions=push_vlan:0x8100,set_field:4196->vlan_vid,goto_table:1
    • table=1, priority=16384,arp,dl_vlan=100 actions=goto_table:3
    • table=3, priority=12320,arp,dl_dst=ff:ff:ff:ff:ff:ff,arp_tpa=10.100.0.254 actions=CONTROLLER:64

    此arp request将送到控制器处理，控制器回复arp reply，此时，控制器已经学习到host1的mac和ip，下发流表：

    • +table=1 priority=8191,in_port=1,dl_vlan=100,dl_src=52:54:00:3f:15:ea hard_timeout=7786 actions=goto_table:4
    • +table=2 priority=12320,ip,dl_vlan=200,nw_dst=10.100.0.10 actions=dec_ttl,set_field:4196->vlan_vid,set_field:0e:00:00:00:00:01->eth_src,set_field:52:54:00:3f:15:ea->eth_dst,goto_table:4
    • +table=2 priority=12320,ip,dl_vlan=100,nw_dst=10.100.0.10 actions=dec_ttl,set_field:4196->vlan_vid,set_field:0e:00:00:00:00:01->eth_src,set_field:52:54:00:3f:15:ea->eth_dst,goto_table:4
    • +table=4 priority=8192,dl_vlan=100,dl_dst=52:54:00:3f:15:ea idle_timeout=11786 actions=pop_vlan,output:1
       

    host1获得网关mac后，发出IP报文（目的IP：10.200.0.10，目的mac，即网关mac，0e:00:00:00:00:01)，此时匹配流表（完整流表flows5）：

    • priority=4096,in_port=sw1p1,vlan_tci=0x0000/0x1fff actions=push_vlan:0x8100,set_field:4196->vlan_vid,goto_table:1
    • table=1, priority=16384,ip,dl_vlan=100,dl_dst=0e:00:00:00:00:01 actions=goto_table:2
    • table=2, priority=12312,ip,dl_vlan=100,nw_dst=10.200.0.0/24 actions=goto_table:3
    • table=3, priority=12317,ip,dl_dst=0e:00:00:00:00:01 actions=CONTROLLER:194

    此IP报文将送到控制器处理。控制器还没有10.200.0.10的mac地址，暂时无法直接封装此报文。控制器将发出arp request，请求host3的mac地址。此时控制器发出的arp request匹配流表（完整流表flows5):

    • table=5, priority=8240,dl_vlan=200,dl_dst=ff:ff:ff:ff:ff:ff actions=pop_vlan,output:sw1p4,output:sw1p5

    host3收到are request后，回复arp reply，此arp reply匹配流表：

    • priority=4096,in_port=sw1p4,vlan_tci=0x0000/0x1fff actions=push_vlan:0x8100,set_field:4296->vlan_vid,goto_table:1
    • table=1, priority=16384,arp,dl_vlan=200 actions=goto_table:3
    • table=3, priority=12320,arp,dl_dst=0e:00:00:00:00:01 actions=CONTROLLER:64

    此arp reply将送到控制器处理。控制器收到arp reply后，已经学习到host3的mac和ip，下发host3的流表：

    • +table=1 priority=8191,in_port=4,dl_vlan=200,dl_src=52:54:00:29:ef:e9 hard_timeout=7798 actions=goto_table:4
    • +table=2 priority=12320,ip,dl_vlan=200,nw_dst=10.200.0.10 actions=dec_ttl,set_field:4296->vlan_vid,set_field:0e:00:00:00:00:01->eth_src,set_field:52:54:00:29:ef:e9->eth_dst,goto_table:4
    • +table=2 priority=12320,ip,dl_vlan=100,nw_dst=10.200.0.10 actions=dec_ttl,set_field:4296->vlan_vid,set_field:0e:00:00:00:00:01->eth_src,set_field:52:54:00:29:ef:e9->eth_dst,goto_table:4
    • +table=4 priority=8192,dl_vlan=200,dl_dst=52:54:00:29:ef:e9 idle_timeout=11798 actions=pop_vlan,output:4

    ✅ 最终效果：

    • faucet 控制器已完成 host1 到 host3 的双向转发路径准备

    • 后续所有 IP 报文将直接通过 datapath 下发的 flow 表处理，无需控制器介入

    你现在提供的日志已经把控制器和 OVS 在连接初期的行为展现得非常清楚了，下面是对这段日志的整体分析与判断：

    ✅ 当前网络行为状态总结：

    1️⃣ 控制器和交换机成功协商 OpenFlow 1.3

    unix#63: negotiated OpenFlow version 0x04

    这表明控制器与交换机的通信协议为 OpenFlow 1.3，是当前主流版本。

    2️⃣ 控制器成功获取交换机的 pipeline 能力

    received: OFPST_TABLE_FEATURES request → sent: OFPST_TABLE_FEATURES reply

    多条 flags=[more] 的回应说明交换机有很多表（table 0～47），且表的功能非常丰富，支持复杂匹配和转发行为。

    3️⃣ 控制器已下发完整的多表流表规则（至少覆盖 table 0～6）

    你贴出来的 OFPST_FLOW reply 是控制器下发后，ovs-vswitchd 查询当前流表的响应输出，格式符合 ovs-ofctl dump-flows 的结果。

    观察流表内容：

    🔸 table=0：

    • 根据 in_port 和 tcp,tp_dst=8080 匹配

    • 动作为 goto_table:1 或 drop

    → 表示做 端口入口分类和基础过滤

    🔸 table=1：

    • 匹配无 vlan 的报文，打 tag（push_vlan + set_vlan_vid）

    • 将其送入 table 2

    → 实现 vlan 标记逻辑

    🔸 table=2：

    • 匹配 IP / ARP / VLAN / MAC / 特殊源，部分 drop，部分 CONTROLLER:96,goto_table:5

    • 存在对 dl_type=0x9000 的 drop（可能是 LLDP）

    → 做 ARP 策略、反向控制路径、广播控制等

    🔸 table=3：

    • 明显是路由选择：基于 nw_dst 做下一跳判断

    → 类似 L3 routing table

    🔸 table=4：

    • 多种协议打给 CONTROLLER，含 ARP, IP, ICMP 等

    • 存在专门处理 0e:00:00:00:00:01 的地址

    → 常见于 Faucet / RYU 的 host learning 或 reactive forwarding

    🔸 table=5：

    • 所有流直接转 goto_table:6，没做判断

    → 起过渡跳板作用

    🔸 table=6：

    • 对不同 VLAN/广播/组播地址的帧进行 pop_vlan + output

    • 同时显式 drop 一些特定广播 / Cisco CDP / STP / 多播 MAC

    → 最终转发表，决定数据帧去哪几个口

    🚨 当前存在的问题：n_packets = 0

    所有流表项都是：

    n_packets=0, n_bytes=0

    说明到目前为止：

    • OVS datapath 没有匹配到任何一个报文

    • 或者 控制器刚刚启动，网络刚刚连通，还没有真实流量发生

    ✅ 当前判断结论：

    • 控制器已成功连接并下发了完整的多表 pipeline

    • 流表设计功能完善，覆盖入口处理 → vlan 标记 → 路由 → controller → 最终输出

    ✅ 当前流表结构快速解读（按 table 顺序）

    表功能说明
    table=0入口ACL +初筛检查 in_port 和 tcp,tp_dst=8080，其余流量放行至 table 1
    table=1VLAN封装把裸包打上 VLAN tag（4196 / 4296）
    table=2二层地址学习包括广播 drop、学习行为（送 controller）、ARP 转发
    table=3路由选择按 nw_dst 决定下一跳
    table=4控制器（router)本地路由/本地地址ARP、IP、ICMP 打给 controller，继续分类或跳转
    table=5二层转发直接跳到 table=6，无实际处理
    table=6BUM转发pop VLAN 后根据 dst MAC 决定 output 到哪些端口

    4.3 host1  ssh host3测试

    host1 ssh host3，这个过程和host1 ping host3相似，只是增加入口ACL检查。由于ACL测试，重启了控制器，所以hos1/host3的mac地址需要重新学习。

    ——host1执行ssh host3操作

    table 5：host1和host3的二层转发

    ovs-dpctl dump-flows 显示 datapath 层的流量状态。

    datapath 使用了掩码匹配方式（tcp(dst=0/0xf000)）下推了一个 TCP megaflow。因为控制面 table=0 中存在一条高优先级规则明确地 drop 了 tp_dst=8080 的 TCP 流量。这会阻止 datapath 生成一个可能“放过”被 drop 的 TCP 流量的 megaflow。OVS 为了安全策略优先，会缩小 datapath 匹配范围，只允许部分端口段的缓存。

    所以ACLOVS某种程度会影响转发性能。
