园区网主要包括终端层、接入层、汇聚层以及核心层，如图1所示，其中，终端层包括接入园区网的终端设备，如：智能终端、手机、个人计算机(personal computer，PC)、打印机等。接入层为终端设备提供园区网接入功能，是园区网的边界。接入层包括接入设备，接入设备可与终端设备通讯连接。接入设备与汇聚层的网络设备通过接口连接。汇聚层将接入层和核心层连接起来，汇聚层包括汇聚设备。核心层为园区网的骨干区域，可与汇聚层以及园区网的其他组成部分(如果有的话)连接。园区网的其他组成部分例如数据中心。核心层可以为园区网的出口，核心层包括核心设备。
此外，核心层的网络设备是通过出口区的网络设备与园区外的网络(Internet(互联网)或广域网(wide area network，WAN))建立连接，从而实现数据信息的交互，其中，园区网中各层的网络设备可以为交换机也可以为路由器，在此不做具体限定。
通常园区网中的网络设备配置有链路状态协议，基于链路状态协议可发现路由，确定路由转发表，指导报文的转发。为了使得园区网中的设备能够转发报文信息，通常各设备的LSDB中存储有园区网中所有设备的链路状态信息。如背景技术所述，为了减少各设备LSDB中存储的链路状态信息，可人为将配置有OSPF协议的网络设备的各个接口添加到指定的OSPF区域中，在不同的区域中单独配置LSDB，但是该方式通过人工配置各个网络设备接口添加到OSPF区域中，费时费力。另外，人在疲劳时，配置大量接口信息易出现配置错误，一旦配置错误，重新配置接口所属的区域，人工作业压力过大。
基于此，本申请提出一种园区网中设备的接口配置方法，以提高园区网中设备接口的配置效率。
应理解，本申请实施例中，设备角色也即网络设备在园区网中的身份标识，该身份标识用于指示网络设备在园区网的网络拓扑中所处的位置，针对本申请而言，设备角色包括：汇聚设备、核心设备以及接入设备。若设备角色为汇聚设备，则与其连接的网络设备可包括核心设备、接入设备以及汇聚设备；若设备角色为核心设备，则与其连接的网络设备可包括核心设备以及汇聚设备；若设备角色为接入设备，则与其连接的网络设备可包括接入设备以及汇聚设备。
OSPF邻居设备也即与网络设备连接且支持OSPF协议的网络设备，可与网络设备通过OSPF报文进行信息交互的网络设备。
OSPF区域，也即在网络设备支持OSPF协议的基础上，将各网络设备分成多个区域，在不同的区域中独立生成LSDB。
其中，“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。
在本申请说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个 或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
园区网中网络设备的设备角色包括汇聚设备、核心设备以及接入设备，下面本申请分别站在不同设备角色的角度来说明各设备如何配置接口所属的OSPF区域的。
图2为站在设备角色为汇聚设备的角度，示意的描述园区网中设备的接口配置方法的流程，汇聚设备可先执行步骤201，获取网络设备的各个接口连接的OSPF邻居设备的设备角色，其中，OSPF邻居设备的设备角色可以包括接入设备或核心设备。
之后执行步骤202，汇聚设备将与设备角色为核心设备的OSPF邻居设备连接的接口添加至第一OSPF区域中。
步骤203，汇聚设备将与第一OSPF邻居设备连接的接口添加至第二OSPF区域中，第一OSPF邻居设备的设备角色为接入设备。
此外，图2中的步骤202和步骤203可以不区分先后顺序，可同时执行，也可按照次序，先执行步骤203后执行步骤202，亦或者先执行步骤202后执行步骤203，在执行顺序上本申请不作具体的限定。
例如，如图3所示，汇聚设备1的接口包括接口1至接口12。OSPF邻居设备包括：核心设备1、核心设备2、接入设备1以及接入设备2。汇聚设备1通过接口1、接口2与核心设备1连接；汇聚设备1通过接口3、接口4与核心设备2连接；汇聚设备1通过接口5、接口6与接入设备1连接；汇聚设备1通过接口7、接口8与接入设备2连接。根据图2示意的园区网中设备的接口配置方法，汇聚设备1可将接口1、接口2、接口3以及接口4添加到OSPF区域1中，可将接口5、接口6、接口7以及接口8均添加到OSPF区域2中。
通过该方式汇聚设备可根据OSPF邻居设备的设备角色，将其与OSPF邻居设备连接的接口自动添加到指定的区域中，而无需一一配置网络设备的各个接口所属的区域，通过该方式既可实现网络设备LSDB中信息的隔离，又可提高园区网中接口的配置效率。
在一个实施例中，网络设备还可将与第二OSPF邻居设备连接的接口添加至第三OSPF区域中，第二OSPF邻居设备的设备角色可以为接入设备。通过该方式可将汇聚设备与不同的接入设备连接的接口，分别添加到不同的OSPF区域，通过该方式将网络设备的与各接入设备连接的接口隔离在不同的OSPF区域中，进一步地减少网络设备LSDB中的链路状态信息。
基于图3中的汇聚设备1的OSPF邻居设备包括：核心设备1、核心设备2、接入设备1以及接入设备2。其中，汇聚设备1还可将汇聚设备1与接入设备1连接的接口5以及接口6添加至OSPF区域2中，将汇聚设备1与接入设备2连接的接口7以及接口8添加至OSPF区域3中，如图4所示。此外，若汇聚设备1还包括接口13以及接口14，且汇聚设备1通过接口13和接口14同接入设备3连接，则汇聚设备1可将接口13以及接口14添加至OSPF区域4中，也即汇聚设备与多个接入设备连接时，则将汇聚设备与各接入设备连接的接口分别添加在不同的OSPF区域中。
在一个实施例中，OSPF邻居设备的设备角色还可以包括汇聚设备；网络设备可将与 设备角色为汇聚设备的OSPF邻居设备连接的接口添加至第一OSPF区域中。如图5所示，仅在图3的基础上进行的具体示意，汇聚设备1的OSPF邻居设备还可以包括汇聚设备2以及汇聚设备3。其中，汇聚设备1通过接口9、接口10与汇聚设备2连接；汇聚设备1通过接口11、接口12与汇聚设备3连接。汇聚设备1可将接口9、接口10、接口11以及接口12添加到OSPF区域1。通过将设备角色为汇聚设备的OSPF邻居设备添加至第一OSPF区域中可以提高设备接口在园区网中的配置效率。
在一个实施例中，网络设备可通过如下方式确定网络设备的OSPF邻居设备的设备角色：
汇聚设备首先获取OSPF邻居设备发送的报文；其中，报文为OSPF协议的报文；OSPF协议的报文中携带有用于指示OSPF邻居设备的设备角色的字段；之后汇聚设备可以根据报文中用于指示OSPF邻居设备的设备角色的字段，获取OSPF邻居设备的设备角色。
园区网中网络设备是通过OSPF协议的报文与OSPF邻居设备来交互信息的，汇聚设备可接收OSPF邻居设备的报文，通过对报文中用于指示OSPF邻居设备的设备角色的字段进行解析，就可以确定OSPF邻居设备的设备角色，如：汇聚设备1接收到OSPF邻居设备发送的报文1，汇聚设备1通过对报文1中用于指示OSPF邻居设备的设备角色的字段进行解析，获悉该OSPF邻居设备的设备角色的为接入设备，汇聚设备1则根据该OSPF邻居设备的设备角色将其与OSPF邻居设备连接的接口添加到指定的OSPF区域中。
本申请与需要人工将网络设备成千上万的接口一一配置所属的OSPF区域的方案相比，仅需人工配置网络设备的设备角色信息，网络设备仅需获取OSPF邻居设备发送的报文中设备角色字段，则可根据OSPF邻居设备的设备角色信息，自动将其接口添加到对应的OSPF区域。相对于需要人工一一配置接口信息，本申请仅需人工配置网络设备的设备角色信息。相对人工一一配置接口所属的OSPF区域，本申请通过网络设备自动配置接口所属的OSPF区域，显著提高了接口的配置效率。此外，由于人工配置成千上万接口信息时出错的可能大，而本申请通过网络设备自动配置接口信息，降低了接口信息的配置错误的可能。
图6为站在设备角色为核心设备的角度，示意的描述园区网中设备的接口配置方法的流程，核心设备可先执行步骤601，获取网络设备的各个接口连接的OSPF邻居设备的设备角色，其中，OSPF邻居设备的设备角色可以包括：汇聚设备以及核心设备。
之后执行步骤602，核心设备将与设备角色为核心设备的OSPF邻居设备连接的接口添加至第一OSPF区域中。
步骤603，核心设备将与第一OSPF邻居设备连接的接口添加至第二OSPF区域中，第一OSPF邻居设备的设备角色为汇聚设备。
此外，图6中的步骤602和步骤603不区分先后顺序，可同时执行，也可按照次序，先执行步骤603后执行步骤602，亦或者先执行步骤602后执行步骤603，再执行顺序上本申请不做具体的限定。
例如，如图7所示，核心设备1的接口包括：接口1至接口8。实际应用时，核心设备不仅包括8个接口，该图仅做例子，并不限定核心设备的接口数量。OSPF邻居设备包括：核心设备2、核心设备3、汇聚设备1以及汇聚设备2。核心设备1通过接口1、接口2与核心设备2连接；核心设备1通过接口3、接口4与核心设备3连接；核心设备1通 过接口5、接口6与汇聚设备1连接；核心设备1通过接口7、接口8与汇聚设备2连接。根据图6示意的园区网中设备的接口配置方法，核心设备1可将接口1、接口2、接口3以及接口4添加到OSPF区域1中，可将接口5、接口6、接口7以及接口8均添加到OSPF区域2中。
通过该方式核心设备可根据OSPF邻居设备的设备角色，将其与OSPF邻居设备连接的接口添加到指定的区域中，将与核心设备连接的接口添加到第一OSPF区域，将与接入设备连接的接口添加到第二OSPF区域，提高园区网中接口的配置效率。
在一个实施例中，核心设备还可将与第二OSPF邻居设备连接的接口添加至第三OSPF区域中，第二OSPF邻居设备的设备角色为汇聚设备。也即，可将图7中与汇聚设备1连接的接口5以及接口6添加到OSPF区域2，将与汇聚设备2连接的接口7以及接口8添加到OSPF区域3中如图8所示，也即核心设备与多个汇聚设备连接时，则将核心设备与各汇聚设备连接的接口分别添加在不同的OSPF区域中。通过该方式可将汇聚设备与各接入设备连接的接口隔离在不同的OSPF区域中，进一步地减少网络设备LSDB中的链路状态信息。
在一个实施例中，网络设备可通过如下方式确定网络设备的OSPF邻居设备的设备角色：
核心设备首先获取OSPF邻居设备发送的报文；其中，报文为OSPF协议的报文；OSPF协议的报文中携带有用于指示OSPF邻居设备的设备角色的字段；之后核心设备根据报文中用于指示OSPF邻居设备的设备角色的字段，获取OSPF邻居设备的设备角色。
园区网中网络设备是通过OSPF协议的报文与OSPF邻居设备来交互信息的，汇聚设备可接收OSPF邻居设备的报文，通过对报文中用于指示OSPF邻居设备的设备角色的字段进行解析，确定OSPF邻居设备的设备角色。如：核心设备1接收到OSPF邻居设备发送的报文2，汇聚设备1通过对报文2中用于指示OSPF邻居设备的设备角色的字段进行解析，获悉该OSPF邻居设备的设备角色的为汇聚设备，核心设备1则根据该OSPF邻居设备的设备角色将其与OSPF邻居设备连接的接口添加到指定的OSPF区域中。
本申请与需要人工将网络设备成千上万的接口一一配置所属的OSPF区域的方案相比，仅需人工配置网络设备的设备角色信息，网络设备仅需获取OSPF邻居设备发送的报文中设备角色字段，则可根据OSPF邻居设备的设备角色信息，自动将其接口添加到对应的OSPF区域。相对于需要人工一一配置接口信息，本申请仅需人工配置网络设备的设备角色信息。相对人工一一配置接口所属的OSPF区域，本申请通过网络设备自动配置接口所属的OSPF区域，显著提高了接口的配置效率。此外，由于人工配置成千上万接口信息时出错的可能性较大，而本申请通过网络设备自动配置接口信息，降低了接口信息的配置错误的可能。
图9为站在设备角色为接入设备的角度，示意的描述园区网中设备的接口配置方法，接入设备可先执行步骤901，获取网络设备的各个接口连接的OSPF邻居设备的设备角色，其中，所述OSPF邻居设备的设备角色可以包括：接入设备以及汇聚设备。
步骤902，如果网络设备的OSPF邻居设备中包括设备角色为接入设备的OSPF邻居设备，则网络设备将与设备角色为汇聚设备的OSPF邻居设备连接的接口添加至第一OSPF区域中，并将与设备角色为接入设备的OSPF邻居设备连接的接口添加至第二OSPF区域 中。
步骤903，如果网络设备的OSPF邻居设备中仅包括设备角色为汇聚设备的OSPF邻居设备，则网络设备将与设备角色为汇聚设备的OSPF邻居设备连接的接口添加至第二OSPF区域中。
此外，图9中的步骤902和步骤903不区分先后顺序，可同时执行，也可按照次序，先执行步骤903后执行步骤902，亦或者先执行步骤902后执行步骤903，再执行顺序上本申请不做具体的限定。
例如，如图10所示，接入设备1的OSPF邻居设备仅包括：汇聚设备1以及汇聚设备2。接入设备1通过接口1、接口2与汇聚设备1连接；接入设备1通过接口3、接口4与汇聚设备2连接。汇聚设备1可将接口1、接口2、接口3以及接口4添加到OSPF区域2中。
园区网的规模不断的扩大，园区网的网络拓扑也会发生变化，接入设备在与汇聚设备连接后，其还可与接入设备连接，由于接入设备除了与汇聚设备连接还与其他接入设备连接，则可将该接入设备与汇聚设备连接的接口从OSPF区域2中移动到OSPF区域1中，其中，OSPF区域1的LSDB相对OSPF区域2的LSDB可以存储更多的链路状态信息。在接入设备连接了汇聚设备后还与接入设备连接时，将接入设备与汇聚设备连接的接口添加到OSPF区域1，而非将该接口与接入设备与其他接入设备连接的接口均配置在OSPF区域2，该方式可以减少OSPF区域2中各网络设备LSDB中存储的链路状态信息。
例如，如图11所示，接入设备1的接口包括：接口1至接口8。实际接入设备不仅包括8个接口，该图仅做例子，并不限定接入设备的接口数量。接入设备1的OSPF邻居设备包括：汇聚设备1、汇聚设备2、接入设备2以及接入设备3。接入设备1通过接口1、接口2与汇聚设备1连接；接入设备1通过接口3、接口4与汇聚设备2连接；接入设备1通过接口5、接口6与接入设备2连接；接入设备1通过接口7、接口8与接入设备3连接。根据图9示意的园区网中设备的接口配置方法，汇聚设备1可将接口1、接口2、接口3以及接口4添加到OSPF区域1中，可将接口5、接口6、接口7以及接口8均添加到OSPF区域2中。
另外，还可将接入设备1与接入设备2连接的接口5、接口6添加到OSPF区域2中，将接入设备1与接入设备3连接的接口7、接口8添加到OSPF区域3中如图12所示，也即接入设备与多个接入设备连接时，则将接入设备与各接入设备连接的接口分别添加在不同的OSPF区域中。通过该方式将网络设备的与各接入设备连接的接口隔离在不同的OSPF区域中，进一步地减少网络设备LSDB中的链路状态信息。
在一个实施例中，网络设备可通过如下方式确定网络设备的OSPF邻居设备的设备角色：
接入设备首先获取OSPF邻居设备发送的报文；其中，报文为OSPF协议的报文；OSPF协议的报文中携带有用于指示OSPF邻居设备的设备角色的字段；之后接入设备根据报文中用于指示OSPF邻居设备的设备角色的字段，获取OSPF邻居设备的设备角色。
园区网中网络设备是通过OSPF协议的报文与OSPF邻居设备来交互信息的，接入设备可接收OSPF邻居设备的报文，通过对报文中用于指示OSPF邻居设备的设备角色的字段进行解析，确定OSPF邻居设备的设备角色，如：核心设备1接收到OSPF邻居设备发送的报文3，接入设备1通过对报文2中用于指示OSPF邻居设备的设备角色的字段进行 解析，获悉该OSPF邻居设备的设备角色为汇聚设备，接入设备1则根据该OSPF邻居设备的设备角色将其与OSPF邻居设备连接的接口添加到指定的OSPF区域中。
本申请与需要人工将网络设备成千上万的接口一一配置所属的OSPF区域的方案相比，仅需人工配置网络设备的设备角色信息，网络设备仅需获取OSPF邻居设备发送的报文中设备角色字段，则可根据OSPF邻居设备的设备角色信息，自动将其接口添加到对应的OSPF区域。相对于需要人工一一配置接口信息，本申请仅需人工配置网络设备的设备角色信息。相对人工一一配置接口所属的OSPF区域，本申请通过网络设备自动配置接口所属的OSPF区域，显著提高了接口的配置效率。此外，由于人工配置成千上万接口信息时出错的可能性较大，而本申请通过网络设备自动配置接口信息，降低了接口信息的配置错误的可能。
