Ubuntu 22.04.5 配置vlan子接口和网桥

使用bond为物理接口，bond配置可以参考：https://blog.csdn.net/qq_50247813/article/details/143630081

实验一、配置vlan子接口

1. 创建bond0，模式为802.3ad；从网卡，ens37，ens38，添加子接口 bond0.10，配置vlanid 10

   root@ubuntu22:/etc/netplan# cat bond0.yaml
   network:
       version: 2
       renderer: networkd
       ethernets:
         ens37:
           addresses: []
           dhcp4: no
           optional: true
         ens38:
           addresses: []
           dhcp4: no
           optional: true
       bonds:
         bond0:
           interfaces: [ens37,ens38]
           parameters:
             mode: 802.3ad
             lacp-rate: fast
             mii-monitor-interval: 100
             transmit-hash-policy: layer3+4
       vlans:
         bond0.10:
           id: 10
           link: bond0
           addresses: [192.168.1.100/24]
           routes:
             - to: 0.0.0.0
               via: 192.168.1.1
           nameservers:
             addresses: [114.114.114.114]
   

2. 查看子接口和vlan信息

   root@ubuntu22:/etc/netplan# netplan apply
   root@ubuntu22:/etc/systemd# ip addr show bond0.10
   6: bond0.10@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
       link/ether 1a:40:de:5e:c3:0c brd ff:ff:ff:ff:ff:ff
       inet 192.168.1.100/24 brd 192.168.1.255 scope global bond0.10
          valid_lft forever preferred_lft forever
       inet6 fe80::1840:deff:fe5e:c30c/64 scope link
          valid_lft forever preferred_lft forever
   root@ubuntu22:/etc/systemd# cat /proc/net/vlan/
   bond0.10  config
   root@ubuntu22:/etc/systemd# cat /proc/net/vlan/config
   VLAN Dev name    | VLAN ID
   Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
   bond0.10       | 10  | bond0
   

实验二、创建网桥

1. 正常绑定接口

   root@ubuntu22:/etc/netplan# cat br0.yaml
   network:
       version: 2
       renderer: networkd
       ethernets:
         ens37:
           addresses: []
           dhcp4: no
           optional: true
         ens38:
           addresses: []
           dhcp4: no
           optional: true
       bonds:
         bond0:
           interfaces: [ens37,ens38]
           parameters:
             mode: 802.3ad
             lacp-rate: fast
             mii-monitor-interval: 100
             transmit-hash-policy: layer3+4
       bridges:
         br0:
           interfaces: [bond0]  # 将物理接口绑定到网桥
           dhcp4: yes		# 如果希望通过DHCP获取IP地址
           # 如果使用静态IP地址，可以配置如下：
           # addresses: [192.168.1.100/24]
           # gateway4: 192.168.1.1
           # nameservers:
           # addresses: [8.8.8.8, 1.1.1.1]
   

   查看网桥接口，已经网桥信息

   root@ubuntu22:/etc/netplan# ifconfig br0
   br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
           inet 192.168.119.130  netmask 255.255.255.0  broadcast 192.168.119.255
           inet6 fe80::7c7a:a7ff:fecb:de52  prefixlen 64  scopeid 0x20<link>
           ether 7e:7a:a7:cb:de:52  txqueuelen 1000  (Ethernet)
           RX packets 548  bytes 72415 (72.4 KB)
           RX errors 0  dropped 0  overruns 0  frame 0
           TX packets 493  bytes 60078 (60.0 KB)
           TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
   
   root@ubuntu22:/etc/netplan# brctl show
   bridge name     bridge id               STP enabled     interfaces
   br0             8000.7e7aa7cbde52       no              bond0
   

2. 绑定子接口

   root@ubuntu22:/etc/netplan# cat br0.yaml
   network:
       version: 2
       renderer: networkd
       ethernets:
         ens37:
           addresses: []
           dhcp4: no
           optional: true
         ens38:
           addresses: []
           dhcp4: no
           optional: true
       bonds:
         bond0:
           interfaces: [ens37,ens38]
           parameters:
             mode: 802.3ad
             lacp-rate: fast
             mii-monitor-interval: 100
             transmit-hash-policy: layer3+4
       vlans:
         bond0.10:
           id: 10
           link: bond0
           addresses: []
       bridges:
         br0:
           interfaces: [bond0.10]
           dhcp4: no
           addresses: [192.168.1.100/24]
           routes:
             - to: 0.0.0.0
               via: 192.168.1.1
           nameservers:
             addresses: [8.8.8.8]
   

   这里和配置vlan 子接口配置很像，但是配置网桥，子接口地址就无需要配置，地址配置在网桥上，子接口作为网桥的一个端口。

   查看接口、vlan、网桥信息

   root@ubuntu22:/etc/netplan# ifconfig br0
   br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
