Telecom Unicom dual-line IP Access service configuration

Nonsense don't say more, directly look at the configuration, I believe a bit of Linux based on all understand.

Unicom Network card:

[Email protected] ~]# CAT/ETC/SYSCONFIG/NETWORK-SCRIPTS/IFCFG-ENS4

Type=ethernet

Bootproto=static

Defroute=yes

Peerdns=yes

Peerroutes=yes

Ipv4_failure_fatal=no

Ipv6init=yes

Ipv6_autoconf=yes

Ipv6_defroute=yes

Ipv6_peerdns=yes

Ipv6_peerroutes=yes

Ipv6_failure_fatal=no

Name=ens4

Device=ens4

Onboot=yes

ipaddr=x.x.x.x # # #联通IP地址

netmask=x.x.x.x # # #联通掩码

gateway=x.x.x.x # # #联通网关

Telecom Network card:

[Email protected] ~]# CAT/ETC/SYSCONFIG/NETWORK-SCRIPTS/IFCFG-ENS5

Type=ethernet

Bootproto=static

Defroute=yes

Peerdns=yes

Peerroutes=yes

Ipv4_failure_fatal=no

Ipv6init=yes

Ipv6_autoconf=yes

Ipv6_defroute=yes

Ipv6_peerdns=yes

Ipv6_peerroutes=yes

Ipv6_failure_fatal=no

Name=ens5

Device=ens5

Onboot=yes

ipaddr=x.x.x.x # #电信ip

netmask=x.x.x.x # # #电信掩码

dns1=114.114.114.114

# # #注意不要配置网关, configured to not be able to surf the internet

Add in/etc/iproute2/rt_tables:

252 Tel

251 CNC

Below my:/etc/iproute2/rt_tables

#

# Reserved values

#

255Local

254Main

253Default

252 Tel

251 CNC

0Unspec

#

# Local

#

#1Inr.ruhep

Execute script:

IP route replace default via Telecom Gateway Dev ENS5

IP Route Flush Table Tel

IP route add default via telecom Gateway Dev ens5 src Telco IP Table Tel

IP rule add from Telco IP table Tel

IP route flush Table CNC

IP route add default via unicom Gateway dev ens4 src unicom ip table cnc

IP rule add from unicom IP table CNC

Double line completion (some machines need to be restarted)

Note: The first script should specify that there is no gateway to configure the network card, such as I do not configure the gateway, then the telecommunications traffic does not know so go, you can go to the default gateway, so you can pass, Unicom has a gateway naturally can pass
