Step 11, carries out cutover operation to the user on the first business router, makes the business of described user be transferred to the second business router；
Step 12, configure core router from described second business router to the described first business router first line of a couplet send described user secondary route, the figure place of described secondary route more than described core router originally preserved corresponding to described user the first via by；
It should be noted that the first via that core router originally preserved is by being that the first business router sends, before adding the second business router, core router is issued to the first business router according to the first via by by the flow of described user.After subscriber installation to the second business router, the second business router sends, to core router, the secondary route that figure place is higher, and secondary route is preserved by core router.When core router issues the flow of described user, according to the longest match principle of route, the secondary route that figure place is higher can be selected, therefore the flow of cutover user can be sent to the second business router.Meanwhile, other users that the first non-cutover of business router is walked are unaffected, and the flow of these users is the same as before, are still sent to the first business router by core router.
Visible, the method of the present embodiment can when not changing the first business router and issuing user gateway route, by on its whole users or a part of subscriber installation to the second business router, and core router is enable correctly to be issued on the second business router by the flow of cutover user.
Specifically, the business router of the present embodiment is specially Broadband Remote Access Server BRAS, after user transfers to the second business router, it is necessary to again cutover user is issued IP address.In the prior art, change IP address it is also desirable to configuration on corresponding change aaa server.Therefore, for avoiding aaa server is being modified, in above-mentioned steps 11, the second business router is carried out configuration operation by excellent needs, make the second business router that cutover user to be authenticated, and after the authentication has been successful, provide, to cutover user, the IP address that this user originally used on the first business router.
Additionally, as a feasible but nonessential preferred version, for convenience of implementing, if cutting user has gateway, directly the network segment cutting user can be route as secondary route, if not having the network segment to route, then can paste and not generate a secondary route for cutting user.That is, in performing above-mentioned steps 12, specifically determine whether described user has gateway；It is then configure described second business router and the network segment of described user is route as described secondary route, and send to described core router；No, then configuring described second business router is the route mask that described user generates one 32, and is sent to described core router as described secondary route by this route mask.
Below in conjunction with an implementation, the method for the present embodiment is described in detail.
In this implementation, service server is specially BRAS (BroadbandRemoteAccessServer, BAS Broadband Access Server), as shown in Figure 2, assume one new BRAS equipment of introducing in existing network, point walk all business on the user 1 on former BRAS (the IP address of user 1 is: 1.1.1.2), specifically by the process of subscriber installation as it is shown on figure 3, include:
The configuration of user 1 is converted into the configuration of new equipment, it is not necessary to the gateway of configuration user 1.
The second line of a couplet equipment of user 1 business is transferred on new BRAS.As shown in Figure 2, assume that second line of a couplet equipment is switch, and divide (the corresponding VLAN1 of user 1, the corresponding VLAN2 of user 2) of business between a user by VLAN, in this step, then on switches switch and on the new BRAS port being connected configure VLAN1.
User 1 normal dialing, user 1 cannot any change of perception here.
After user 1 reaches the standard grade, message identifying is delivered on new BRAS.
User 1 is authenticated by new BRAS by aaa server, and user 1 still provides IP address (1.1.1.2) as before.
New BRAS, according to Routing Protocol (such as open type shortest path priority protocol OSPF, link-state routing protocol ISIS), generates a secondary route for user 1, and notices the secondary route of user 1 to core router.
Core router CR this locality preserves the secondary route of user 1；Assume that core router currently saves the user 1 first via for former BRAS by 1.1.0.1/16 and newly added secondary route 1.1.1.2/32 (first via is before user 1 is by cutover by 1.1.0.1/16, former BRAS provide to core routing device) simultaneously.
User 2 (assuming that user DI address is 1.1.1.1) on former BRAS accesses in network development process, after its return packet arrives core router, 1.1.0.1/16 can be matched when core router query routing entry, the down hop of this route is former BRAS, so message can correctly be delivered on former BRAS；User 1 accesses in network development process, when its return packet arrives core router, can match 1.1.1.2/32 (neglecting 1.1.0.1/16) when query routing entry, the down hop of this route is new BRAS, so message can correctly be delivered on new BRAS；Consequently, it is possible to be achieved that the cutover of user 1, have no effect on former BRAS and normally receive the backhaul traffic of user.
Additionally, embodiments of the invention also provide for a kind of cut over device, as shown in Figure 4, including:
