CentOS7设置双网关

1.1 ip地址

ip地址192.168.235.132 网关192.168.235.254
ip地址192.168.233.5 网关 192.168.233.1

1.2 在最末尾增加两行配置

cat /etc/iproute2/rt_tables 
#
# reserved values
#
255	local
254	main
253	default
0	unspec
#
# local
#
#1	inr.ruhep
252 e1
251 e0

1.3 配置网关

cat network_two_gateway.sh 
ip route flush table e0
ip route add default via 192.168.235.254 dev eth0 src 192.168.235.132 table e0
ip rule add from 192.168.235.132 table e0
ip route flush table e1
ip route add default via 192.168.233.1 dev eth1 src 192.168.233.5 table e1
ip rule add from 192.168.233.5 table e1
