How does a router and another router set up a connection?

1, everyone first look at a global map, b for the second route, we want to reach the target of the first route does not need to change any settings, only need to change the second route B

2, separate route B to the computer to set up, Bwan mouth first, only LAN access to the computer

3, the browser to open the management interface of the router, to change the B routed LAN port IP address

4, turn off the B routing DHCP function

5, the connection method, after the B is set, b Wan mouth idle (also can not idle, but the setting is different from this, personal feeling this way best)

6, B as no line by, as usual set, the last B LAN port to a LAN port successfully

Note:

1, two routing ip can not be the same

2, the second route does not open DHCP

3, third, four steps can not be reversed,
