创建这两个网桥主要是为了让
kind上节点通过虚拟交换机连接到containerLab，为什么不直连接containerLab，如果10.1.5.10/24使用vethPair和containerLab进行连接，10.1.5.11/24就没有额外的端口进行连接

calico.yaml 参数解释
-
calico_backend: "vxlan"- 含义: 配置
calico_backend使用vxlan模式，默认是bird模式
- 含义: 配置
-
- name: CALICO_IPV4POOL_IPIP- 含义: 用于启用或禁用
IPIP（IP in IP）隧道。 value: "Never":IPIP会禁用，此处使用VXLAN模式
- 含义: 用于启用或禁用
-
- name: CALICO_IPV4POOL_VXLAN- 含义: 用于启用或禁用
VXLAN隧道。 value: "CrossSubnet":VXLAN隧道会在跨越不同子网的情况下启用，而在同一个子网内的流量不会使用VXLAN隧道。
- 含义: 用于启用或禁用

clab-calico-vxlan-crosssubnet-control-plane主机接受到数据包后，解封装数据包 - 解封装后发现内部的数据包，目的地址为

cali54c92472bff网卡，最终会把数据包送到cni-42v4l主机
总结
跨节点同

vxlan.calico 模式为 vxlan 模式，数据包会进行 vxlan 封装并送往 eth0 接口，那么 vxlan 封装的外层数据的目的 ip 又是谁？可以查看 fdb 表信息确定外层数据的目的 ip

- 总结：查看上面抓包图片，可以分析到，在
vxlan模式中，数据包的转发流程中：- 数据包在送到
vxlan接口之前，mac地址，每经过一个节点，源mac和 目标mac均会发生改变。送到vxlan接口之后，内层数据包源mac使用本机vxlan.calico网卡mac地址，目标mac使用目的Pod所在 Node 节点的vxlan.calico网卡mac地址， 目的Pod所在 Node 节点的vxlan.calico网卡mac地址通过FDB学习获得。外层数据包源mac使用本机net0网卡mac地址，目标mac使用目的网关节点的网关IP网卡mac地址 - 数据包在送到
vxlan接口之前，源ip和 目标ip不会发生改变。送到vxlan接口之后，内层源ip和 目标ip不会发生改变，会在原数据包网络层上进行封包，多一次封装外层源ip和 目标ip，源ip使用本机net0网卡ip地址，目标ip使用目的Pod所在 Node 节点的net0网卡ip地址， 目的Pod所在 Node 节点的net0网卡ip地址通过FDB获得

calibcba671fe41网卡，最终会把数据包送到cni-cmb4s主机
总结
vxlan模式是CrossSubnet的场景下: 跨节点同Node网段Pod网络通讯，数据包通过3层路由送到对端Node节点，而不会通过vxlan模式进行数据包封装
vxlan模式是CrossSubnet的场景下: 跨节点不同Node网段Pod网络通讯，数据包通过vxlan模式进行数据包封装送到对端Node节点
Pod间的通信经由vxlan的三层隧道转发，相比较ipip的二层隧道来说，vxlan隧道的开销较大，但其安全性也更高一些。
Service 网络通讯
可以查看此文档 Calico IPIP 模式 中，Service 网络通讯，数据包转发流程一致
