linux配置bridge (不同网段)

Posted 2020-12-09 -夏了夏天-

1.# brctl show

2.配置多个不同网段

# ifconfig fpp0-0 192.168.0.20
# ifconfig fpp0-1 192.168.1.20
# ifconfig fpp0-2 192.168.2.20
# ifconfig fpp0-3 192.168.3.20
#
# ifconfig fpp31-0 192.168.30.20
# ifconfig fpp31-1 192.168.31.20
# ifconfig fpp31-2 192.168.32.20
# ifconfig fpp31-3 192.168.33.20

3.把不同网段接口添加到虚拟bridge br0

# brctl addif br0 fpp0-0

# brctl addif br0 fpp0-1

# brctl addif br0 fpp0-2

# brctl addif br0 fpp0-3

# brctl addif br0 fpp31-0

# brctl addif br0 fpp31-1

# brctl addif br0 fpp31-2

# brctl addif br0 fpp31-3

4.使能端口up

# ifconfig fpp0-0 up
# ifconfig fpp0-1 up
# ifconfig fpp0-2 up
# ifconfig fpp0-3 up
# ifconfig fpp31-0 up
# ifconfig fpp31-1 up
# ifconfig fpp31-2 up
# ifconfig fpp31-3 up
5.vi /etc/dhcp/dhcpd.conf

ddns-update-style interim;
ignore client-updates;
authoritative;
allow booting;
allow bootp;
allow unknown-clients;

subnet 192.168.10.0 netmask 255.255.255.0 {
range dynamic-bootp 192.168.10.2 192.168.10.255;
option routers 192.168.10.1;
option broadcast-address 192.168.10.255;
default-lease-time 600;
max-lease-time 7200;
}

6.启动dhcp服务

#dhcpd
