########team链路聚合###

1.team也是链路聚合的一种方式
最多支持8块网卡
支持模式：
广播容错 broadcast
轮询 roundrobin
主备 activebackup
负载均衡 loadbalance
2.配置
nmcli connection add con-name team0 ifname team0 type team config '{"runner":{"name":"activebackup"}}' ip4 172.25.254.106/24
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
3.测试
watch -n 1 teamdctl team0 stat
ifconfig eth0 down

ifconfig eth0 up

########网桥######

配置方式
vim /etc/sysconfig/network-scripts/ifcfg-enp0s25
DEVICE=enp0s25       ##设备名称
ONBOOT=yes       ##开启服务设备自动激活
BOOTPROTO=none       ##网卡工作状态
BRIDGE=br0       ##网卡开启的网桥接口
vim /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.25.254.6
NETMASK=255.255.255.0
TYPE=Bridge       ##网络接口类型是桥接

systemctl stop NetworkManager.service
systemctl restart network
systemctl start NetworkManager.service
[root@foundation6 network-scripts]# ifconfig
br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        inet 172.25.254.6 netmask 255.255.255.0 broadcast 172.25.254.255
        inet6 fe80::221:ccff:fe71:13d0 prefixlen 64 scopeid 0x20<link>
        ether 00:21:cc:71:13:d0 txqueuelen 0 (Ethernet)
        RX packets 58 bytes 6962 (6.7 KiB)
        RX errors 0 dropped 0 overruns 0 frame 0
        TX packets 25 bytes 3421 (3.3 KiB)
        TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
命令管理方式
添加
systemctl stop NetworkManger
brctl show       ##显示桥接的设备
brctl addbr br0       ##添加桥接设备
brctl addif br0 eth0   ##将网卡加入桥接设备
ifconfig eth0 up
ifconfig br0 172.25.254.x netmask 255.255.255.0   ##添加ip地址
brctl show
ping 172.25.254.250   ##测试结果
删除
ifconfig br0 down
brctl delif br0 eth0
brctl delbr br0

brctl show

#########ipv6########

1.
internet proto version 6
ipv4 32/2        ##地址枯竭子网掩码24 16 8
ipv6 128/2       ##子网掩码16 32 48 64 80
128/2----------------> 128/8 16 -----> 0-f
2017:0:0:0:f:0:0:1/48   ##
2017::f:0:0:1       ##
2017:0:0:0:f::1       ##代表相同的网络（：：代表省略中间的0，只能使用一次）

2.IPV6的设置

vim /etc/sysconfig/network-scripts/ifcfg-eth0

systemctl restart network

测试：
[root@localhost ~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        inet 172.25.254.106 netmask 255.255.255.0 broadcast 172.25.254.255
        inet6 2017::d prefixlen 64 scopeid 0x0<global>
        inet6 fe80::5054:ff:fe00:60a prefixlen 64 scopeid 0x20<link>
        ether 52:54:00:00:06:0a txqueuelen 1000 (Ethernet)
        RX packets 11859 bytes 716655 (699.8 KiB)
        RX errors 0 dropped 0 overruns 0 frame 0
        TX packets 651 bytes 34081 (33.2 KiB)
        TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

[root@localhost ~]# ping6 2017::a       ##用ping6测试IPV6地址在同一网段结果
