team链路聚合，网桥的配置，IPV6
1.team
(1)
team也是链路聚和的一种方式
最多支持8块网卡
支持模式：
broadcast ##广播容错
roundrobin ##轮询
activebackup ##主备
loadbalance ##负载均衡
(2)配置
nmcli connection add con-name team0 ifname team0 type config '{"runner":{"name":"activebackup"}}' ip4 172.25.254.105/24
nmcli connection add con-name eth0 ifname eth0 type team-slave master team0
nmcli connection add con-name eth1 ifname eth1 type team-slave master team0
teamdctl team0 stat ##查看状态
(3)测试
watch -n 1 teamdctl team0 stat
ifconfig eth0 down
ifconfig eth0 up
2.网桥
配置方式
368 systemctl stop NetworkManager
369 systemctl status NetworkManager
370 cd /etc/sysconfig/network-scripts/
371 ls
372 vim ifcfg-enp0s25
373 cat ifcfg-enp0s25
DEVICE=enp0s25 ##设备名称
ONBOOT=yes ##开启服务设备自动**
BOOTPROTO=none ##网卡工作状态
BRIDGE=br0 ##网卡开启的网桥接口
374 vim ifcfg-br0
375 cat ifcfg-br0
DEVICE=br0
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.25.254.5
NETMASK=255.255.255.0
TYPE=Bridge ##网络接口类型是桥接
376 systemctl restart network ##这个必须在systemctl stop NetworkManager之后，否则会记录网络状态
377 systemctl start NetworkManager
378 ifconfig
br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.25.254.5 netmask 255.255.255.0 broadcast 172.25.254.255

ether 00:21:cc:69:48:08 txqueuelen 0 (Ethernet)
RX packets 32209 bytes 46860854 (44.6 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 16081 bytes 1067023 (1.0 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
379 reboot
成功！
命令管理方式
首先删除其他配置ifcfg-*,只留下lo
systenctl stop NetworkManager
brctl show
brctl addbr br0 ##添加网桥
brctl addif br0 eth0 ##给网桥添加网卡
ifconfig eth0 up ##使网卡**
ifconfig bro 172.25.254.X netmask 255.255.255.0
brctl show
ping 172.25.254.250
删除
ifconfig br0 down
brctl delif br0 eth0
brctl delbr br0
brctl show
3.ipv6
(1)
internet protocol version 6
ipv4 32/2 地址枯竭
ipv6 128/2
128/2--------> 128/8 16 --------->0-f
