The demonstrative structure of MS-update messages and MS-remove messages described in detail above, those skilled in the art
It is to be appreciated that this description is only exemplary, it is not used to form restriction to embodiment of the present invention.
With reference to specific networking, embodiment of the present invention is illustrated.
Fig. 2 is that the first schematic diagram is configured in the MS in embodiment of the present invention LISP networks.
As shown in Fig. 2, MS1, MS2 and MS3 are connected respectively to ALT networks.MS1 connection XTR1 and XTR2；MS2 connections XTR1
And XTR2；MS3 connections XTR3.
The upper EID prefixes of XTR1 include：10.0.0.0/24 and 20.0.0.0/24, belong to website 1；The upper EID prefixes packets of XTR2
It includes：20.0.0.0/24 and 21.0.0.0/24, belong to website 1；The upper EID prefixes of XTR3 include：10.0.0./24 and 30.0.0.0/
24；Wherein 10.0.0./24 belong to website 1, and 30.0.0.0/24 belongs to website n.
XTR1 is connected respectively to MS1 and MS2, therefore the EID prefixes hung under XTR1 will be safeguarded on MS1 and MS2.Similarly,
XTR2 is connected respectively to MS1 and MS2, therefore the EID prefixes hung under XTR2 will be safeguarded on MS1 and MS2.Therefore, MS1 and MS2
On the EID prefixes to be configured include：10.0.0.0/24 20.0.0.0/24 and 21.0.0.0/24.XTR3 is connected to MS3, therefore
The upper EID prefixes to be configured of MS3 include：10.0.0.0/24 with 30.0.0./24.It can be seen that the EID prefixes of MS3 and MS1 are handed over
Collection is 10.0.0.0/24.
Fig. 3 is MS configuration methods flow chart shown in Fig. 2.
As shown in figure 3, this method includes：
Step 301：Manual configuration is performed in MS1, is specifically included：The tunnel router of MS1 connections is included in MS1 receptions
The EID prefixes (i.e. 10.0.0./24,20.0.0.0/24 and 21.0.0.0/24) of (i.e. XTR1 and XTR2) and the website of website 1
The user configuration information of mark.MS1 is locally generated configuration list item based on the EID prefixes received and site identity, so as to really
Determine website and the EID prefixes that MS1 needs are safeguarded.Moreover, because MS2 and MS1 has EID prefix intersection 20.0.0.0/24, because
MS2 is determined as synchronous MS by this；Since MS3 and MS1 has EID prefix intersection 10.0.0.0/24, MS3 is also determined as
Synchronous MS.All EID prefixes safeguarded in MS1 equipment can be all synchronized to MS2, by the website 1 safeguarded in MS1 equipment
10.0.0.0/24 EID prefixes are synchronized to MS3.
It specifically, can be as follows to be configured in MS1 equipment：
site 1
eid-prefix 10.0.0.0 24 alternative-ms ip-address of MS2
eid-prefix 20.0.0.0 24 alternative-ms ip-address of MS2
eid-prefix 21.0.0.0 24 alternative-ms ip-address of MS2
eid-prefix 10.0.0.0 24 alternative-ms ip-address of MS3
Wherein, using alternative-ms orders for every EID prefix, the IP as the synchronization MS that backs up is specified
Location.
Step 302：MS1 sends MS-update messages to synchronous MS.
Specifically, MS-update messages use the basic format of LISP protocol message, and wherein Type is 6, MS-update
Site identity (i.e. website 1) is stored in message, and the EID prefixes of website are also stored in MS-update messages.MS-
The purpose IP address of update messages is the IP address that alternative-ms orders are configured.
Site identity (i.e. website 1) is stored with into the MS-update messages transmitted by MS2 in MS1.Moreover, MS-
The EID prefixes stored in update messages include：10.0.0.0/24 20.0.0.0 24 and 21.0.0.0 24.The MS-
The purpose IP address of update messages is the IP address of MS2.
Site identity (i.e. website 1) is stored with into the MS-update messages transmitted by MS3 in MS1.Moreover, MS-
The EID prefixes of update packet storages include：10.0.0.0/24.The purpose IP address of the MS-update messages is the IP of MS3
Address.
Since ALT networks have the routing iinformation of all MS, as long as MS-update messages are transmitted to ALT nets by MS1
Message can be correctly transmitted to MS2 and MS3 respectively by network, ALT networks.
Step 303：Synchronous MS respectively performs configuration based on MS-update messages.
After MS2 receives MS-update messages, according to EID prefixes and site identity that MS-update messages carry, at this
Machine generates the EID prefixes about website 1：10.0.0.0/24 the configuration list item of 20.0.0.0 24 and 21.0.0.0 24.As it can be seen that
Since the EID prefixes on MS2 have all been synchronized by MS1, manual configuration, therefore significantly drop are no longer needed on MS2
The low configuration work amount of MS2.
After MS3 receives MS-update messages, according to EID prefixes and site identity that MS-update messages carry, at this
Machine generates the EID prefixes about website 1：10.0.0.0/24 configuration list item.As it can be seen that due to the EID prefixes on MS3：
10.0.0.0/24 it is synchronized by MS1, therefore manual configuration EID prefixes is no longer needed on MS3：10.0.0.0/24,
And only need manual configuration EID prefixes：30.0.0./24, therefore the configuration work amount of MS3 is significantly reduced.Moreover, MS3 is only tieed up
The EID prefix informations of oneself connected website are protected, significantly mitigate this equipment pressure.
In addition, when MS1 breaks down, since MS2 still maintains the website of MS1 and EID prefixes, network still can
Normal operation.For another example, when MS2 breaks down, since MS1 still maintains the website of MS2 and EID prefixes, network is still
It so can normal operation.
When deleting configuration list item on MS1, other MS equipment can be synchronized to by controlling message MS-remove.
Step 304：MS1 sends MS-remove messages to synchronous MS.
For example, when deleting EID prefix 20.0.0.0/24 on MS1 by hand, message MS- will be controlled by ALT networks
Remove messages are sent to MS2.Due to deleting EID prefix 20.0.0.0/24 by hand on MS1, MS3 is had no effect on, therefore not
It needs to send MS-Remove messages to MS.
Specifically, MS-remove messages use the basic format of LISP protocol message, and wherein Type is 7, MS-remove
Site identity (i.e. website 1) is stored in message.Moreover, the EID prefixes of website 1 are also stored in MS-remove messages
(20.0.0.0/24)。
When MS-remove messages include site identity and EID prefixes, MS-remove messages are used to indicate synchronous MS
Delete the configuration list item of the EID prefixes comprising website corresponding to the site identity.
When MS-remove messages include site identity and do not include EID prefixes, MS-remove messages are used to indicate together
Step MS deletes all configuration list items of website corresponding to the site identity.
Step 305：Synchronous MS is based on MS-Remove messages and deletes configuration list item.
The MS-remove messages include site identity (i.e. website 1), and MS-remove messages also include EID prefixes：
20.0.0.0/24.After MS2 receives MS-remove messages, the site identity and EID prefixes in MS-remove messages are at this
The configuration list item of 20.0.0.0/24 is deleted in equipment.
Fig. 4 is that the second schematic diagram is configured in the MS in embodiment of the present invention LISP networks.
As shown in figure 4, MS1, MS2 and MS3 are connected respectively to ALT networks.MS1 connections XTR1；MS2 connections XTR2；MS3 connects
Meet XTR3.
The upper EID prefixes of XTR1 include：10.0.0.0/24 and 20.0.0.0/24, belong to website 1；The upper EID prefixes packets of XTR2
It includes：20.0.0.0/24 and 21.0.0.0/24, wherein 20.0.0.0/24 belong to website 1, and 21.0.0.0/24 belongs to website 2；
The upper EID prefixes of XTR3 include：10.0.0./24 and 30.0.0.0/24；Wherein 10.0.0./24 belong to website 1,30.0.0.0/24
Belong to website n.
XTR1 is connected to MS1, therefore the EID prefixes hung under XTR1 are safeguarded on MS1：10.0.0.0/24 and 20.0.0.0/
24.Similarly, XTR2 is connected to MS2, therefore the EID prefixes hung under XTR2 are safeguarded on MS2：20.0.0.0/24 and 21.0.0.0/
24.Therefore, the EID prefixes (i.e. EID prefixes intersection) that will be configured on MS1 and MS2 include：20.0.0.0/24.XTR3 is connected to
MS3, therefore the EID prefixes to be configured on MS3 include：10.0.0.0/24 with 30.0.0./24.It can be seen that MS3 and MS1
EID prefix intersections are 10.0.0.0/24.
Fig. 5 is MS configuration methods flow chart shown in Fig. 4.
As shown in figure 5, this method includes：
Step 501：Manual configuration is performed in MS1, is specifically included：The tunnel router of MS1 connections is included in MS1 receptions
The user configuration information of the EID prefixes (i.e. 10.0.0./24,20.0.0.0/24) of (i.e. XTR1) and the site identity of website 1.
MS1 is locally generated configuration list item based on the EID prefixes received and site identity, so that it is determined that the website that MS1 needs are safeguarded
And EID prefixes.Moreover, because MS2 and MS1 has EID prefix intersection 20.0.0.0/24, therefore MS2 is determined as synchronizing
MS；Since MS3 and MS1 has EID prefix intersection 10.0.0.0/24, MS3 is also determined as to synchronous MS.That is, it needs
The EID prefixes 20.0.0.0/24 safeguarded in MS1 equipment is synchronized to MS2, by maintenance site 1 in MS1 equipment
10.0.0.0/24 EID prefixes are synchronized to MS3.
It specifically, can be as follows to be configured in MS1 equipment：
site 1
eid-prefix 20.0.0.0 24 alternative-ms ip-address of MS2
eid-prefix 10.0.0.0 24 alternative-ms ip-address of MS3
Wherein, using alternative-ms orders for every EID prefix, the IP as the synchronization MS that backs up is specified
Location.
Step 502：MS1 sends MS-update messages to synchronous MS.
Specifically, MS-update messages use the basic format of LISP protocol message, and wherein Type is 6, MS-update
Storage site identifies (i.e. website 1).Moreover, MS-update is also stored with the EID prefixes of website.The purpose of MS-update messages
IP address is the IP address that alternative-ms orders are configured.
In MS1 into the MS-update messages transmitted by MS2, it is stored with site identity (i.e. website 1).Moreover, the MS-
The EID prefixes of update packet storages include：20.0.0.0/24.The purpose IP address of the MS-update messages is the IP of MS2
Address.
In MS1 into the MS-update messages transmitted by MS3, it is stored with site identity (i.e. website 1).Moreover, the MS-
The EID prefixes of update packet storages include：10.0.0.0/24.The purpose IP address of the MS-update messages is the IP of MS3
Address.
Since ALT networks have the routing iinformation of all MS, as long as MS-update messages are transmitted to ALT nets by MS1
Message can be correctly transmitted to MS2 and MS3 by network, ALT networks.
Step 503：Synchronous MS respectively performs configuration based on MS-update messages.
After MS2 receives MS-update messages, according to EID prefixes and site identity that MS-update messages carry, at this
Machine generates the EID prefixes about website 1：20.0.0.0/24 configuration list item.As it can be seen that due to the EID prefixes on MS2：
20.0.0.0/24 it is synchronized by MS1, therefore manual configuration EID prefixes is no longer needed on MS2：20.0.0.0/24,
And only need manual configuration EID prefixes：21.0.0./24, therefore the configuration work amount of MS2 is significantly reduced.
After MS3 receives MS-update messages, according to EID prefixes and site identity that MS-update messages carry, at this
Machine generates the EID prefixes about website 1：10.0.0.0/24 configuration list item.As it can be seen that due to the EID prefixes on MS3：
10.0.0.0/24 it is synchronized by MS1, therefore manual configuration EID prefixes is no longer needed on MS3：10.0.0.0/24,
And only need manual configuration EID prefixes：30.0.0./24, therefore significantly MS3 reduces configuration work amount.Moreover, MS3 is only maintained
Oneself connect the EID prefix informations of website, significantly mitigate this equipment pressure.
When deleting configuration list item on MS1, other MS equipment can be synchronized to by controlling message MS-remove.
Step 504：MS1 sends MS-remove messages to synchronous MS.
For example, when deleting EID prefix 20.0.0.0/24 on MS1 by hand, message MS- will be controlled by ALT networks
Remove messages are sent to MS2.Due to deleting EID prefix 20.0.0.0/24 by hand on MS1, MS3 is had no effect on, therefore not
It needs to send MS-Remove messages to MS.
Specifically, MS-update messages use the basic format of LISP protocol message, and wherein Type is 7, MS-update
Packet storage has site identity (i.e. website 1), and MS-update messages are also stored with the EID prefixes (20.0.0.0/ of website 1
24)。
When MS-update messages include site identity and EID prefixes, MS-remove messages are used to indicate synchronous MS and delete
