Situation is that the party a by unicom pulled a special line, special line data of 13 counties and cities,
And for each of the counties and cities divided the vlan and the special line together to connect to the center room core switch (core switch Settings for each of the counties and cities respectively corresponding vlan,
Such as a county LAN addresses itself for 192.168.0. X

Core interface VLAN is configured on the switch center room 108
No IP proxy arp
-IP address 192.168.108.1 255.255.255.0
The description of a county), the room is also the 192.168.0. X 192.168.1. X segment address, such as the following before 13 counties because of the network planning, there is also the same network segment and address and center machine room, because of various reasons (one of the most important thing is that each of the counties and cities are independent business system before, because all the year round out software maintenance costs, lead to can't change the network address database, and database connection way has already written to death in the cs architecture software, can't change the network segment address),

At present the connection of the counties are special line transfer through light cat call each county of layer 2 switches on line access to the room after the summary of the core switches on,

Requirements: how to do can be in various counties city itself under the condition of invariable LAN address can access to the room of the business system (192.168.0. X segment address), center can take to a server of various data,


In each of the counties and cities can you add a router, the router is added to what position, what needs to be carried out on the router configuration, wan address, vlan needs to consider what you
If the counties and cities have layer 3 switches can not add the router is implementation requirements ideas about what is
There are more economic way to solve the problem

CodePudding user response:

Branch can't move that can only move at the center of the conflict segment all change, no choice,

CodePudding user response:

Add a routing between branch network and special line, branch address remains the same, routing do NAT translation, and the branch server mapping needs to be accessed

CodePudding user response:

Routers can do NAT converts the network segment of branch and the center, this online is out other segment visited each other; Buy a firewall or NAT, but a firewall generally support flow is not big, see your branch of the business flow of general county flow is possible.
