ubuntu18.04系统bond mode4的多网卡绑定测试

测试过程

虚拟机使用kvm创建，名称为bond-mode4，操作系统为ubuntu18.04

1、宿主机创建虚拟网桥，由于为测试用，并无实际的物理连接。

brctl addbr br-test1
brctl addbr br-test2
brctl addbr br-test3
brctl addbr br-test4

2、给虚拟机挂载虚拟网卡

virsh attach-interface --type bridge --source br-test1 vm_domain
virsh attach-interface --type bridge --source br-test2 vm_domain
virsh attach-interface --type bridge --source br-test3 vm_domain
virsh attach-interface --type bridge --source br-test4 vm_domain

3、使用kvm创建虚拟机bond-mode4

3、给bond-mode4的netplan配置

root@bond-mode4:/etc/netplan# cat 50-cloud-init.yaml 
network:
  ethernets:
    eth0:
      dhcp4: no
    eth1:
      dhcp4: no
    eth2:
      dhcp4: no
    eth3:
      dhcp4: no
  bonds:
    bond1:
      dhcp4: no
      optional: true
      interfaces:
      - eth0
      - eth1
      - eth2
      - eth3
      parameters:
        mode: 802.3ad
  version: 2
root@bond-mode4:/etc/netplan# ip a

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether fa:16:3e:cf:02:de brd ff:ff:ff:ff:ff:ff
    inet 100.114.0.22/16 brd 100.114.255.255 scope global noprefixroute eth4
       valid_lft forever preferred_lft forever
    inet6 fe80::610:43eb:15d4:3b4d/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
7: bond1: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether fa:16:3e:9c:dc:d3 brd ff:ff:ff:ff:ff:ff
    inet 169.254.217.204/16 brd 169.254.255.255 scope link noprefixroute bond1
       valid_lft forever preferred_lft forever
    inet6 fe80::f816:3eff:fe9c:dcd3/64 scope link 
       valid_lft forever preferred_lft forever

由于bond1获取不到ip地址，所以ip地址为169.254

测试结论

从测试过程来看，可以直接配置多网卡的mode4,后续测试需要交换机端配合测试。
