CISCO routers achieve dual-line access

The first step for a CISCO router to implement dual-line access: configure the cnc interface: interface GigabitEthernet5/1 ip address 60.10.135.11 255.255.255.255.255.ip nat outside to configure the tel interface: interface GigabitEthernet5/9 ip address 219.148.157.22 255.255.255.255.252 ip nat outside configure Intranet interface: interface GigabitEthernet5/2 ip address 192.168.0.1 255.255.255.0 ip nat inside Step 2: configure accelist-listaccess-list 100 permit ip 192.168.0.0 0.0.255 any step 3: configure the address pool ip address nat pool pool2 of the cnc and tel respectively 60.10.135.11 60.10.135.11 netmask bandwidth nat pool pool1 bandwidth netmask bandwidth limit 252 Step 4: configure two route-maproute-map isp2 permit 10 match ip address 100 match interface GigabitEthernet5/1! Route-map isp1 permit 10 match ip address 100 match interface GigabitEthernet5/9 Step 5: configure two natip nat inside source route-map isp1 pool pool1 overload ip nat inside source route-map isp2 pool pool2 overload Step 6: configure the default route from China Telecom: ip route 0.0.0.0 0.0.0.0 219.148.157.21 the destination address is China Netcom's access network. For example, ip route 202.99.168.0 255.255.248.0 60.10.135.1 adds all China's network segment.
