配置MPLS TE隧道属性示例（亲和属性）
组网需求
如图3-13所示，共用链路LSRA→LSRB的带宽50Mbit/s，其余各链路的最大可预留带宽均是100Mbit/s，BC0带宽是100Mbit/s。
LSRA上存在两条到达LSRC的RSVP TE隧道Tunnel1和Tunnel2。两隧道的带宽要求都是40Mbit/s。两条隧道的带宽总和（80Mbit/s）大于共用链路LSRA→LSRB的带宽50Mbit/s，且Tunnel2的优先级高于Tunnel1，允许发生抢占情况。
要求根据各链路上的管理组属性，使用隧道的亲和属性及掩码，使LSRA上的Tunnel1使用LSRB→LSRC的一条物理链路，Tunnel2使用LSRB→LSRC的另一条。
配置思路
采用如下的思路配置隧道属性：
配置RSVP TE隧道，请参见配置RSVP-TE隧道示例中的配置思路。
在各节点的隧道出接口上配置链路的管理组属性。
通过查看链路的管理组属性及组网需求，确定并配置各隧道的亲和属性及掩码。
根据需求配置各隧道的优先级。
数据准备
为完成此配置例，需准备如下的数据：
各节点的OSPF进程号、所在的OSPF区域
隧道沿途的链路最大可预留带宽和各BC带宽
LSRA→LSRB的管理组属性、LSRB→LSRC的管理组属性
各隧道的亲和属性及掩码
隧道接口的接口编号、IP地址、目的地址、隧道带宽、隧道的优先级分别、隧道信令协议（取缺省的RSVP-TE）
操作步骤
- 配置各接口的IP地址
按照图3-13配置各接口的IP地址和掩码，包括各Loopback接口。
具体配置过程略。
- 配置IGP协议
在所有节点上配置OSPF协议，发布各网段及LSR ID主机路由。
具体配置过程略。
- 配置MPLS基本能力，使能MPLS TE、RSVP-TE及OSPF TE，并在入节点使能CSPF

Tunnel1的亲和属性的掩码是0x11011，因此亲和属性值需比较的是前两位和后两位；Tunnel1的亲和属性值为0x10101，因此Tunnel1在选路时会选择管理组属性值前两位是10且后两位是01的链路。根据上述规则，Tunnel1选择的链路是LSRA的GE0/1/0（管理组属性值为0x10001）、LSRB的GE0/2/0（管理组属性值为0x10101）。
配置完成后，可在LSRA上查看Tunnel的状态：

也可在LSRB上用display mpls te tunnel diagnostic命令来检查隧道的出接口。

- 检查配置结果
配置完成后，可用display interface tunnel或display mpls te tunnel-interface命令在LSRA上查看Tunnel的状态，可以看到Tunnel1的状态为Down，这是由于链路的最大可预留带宽不够，带宽被高优先级的Tunnel2抢占。
用display mpls te cspf tedb node命令再次查看TEDB，跟踪各链路上带宽的变化情况，证实Tunnel2经过LSRB的GE0/3/0。
或者直接在LSRB上用display mpls te tunnel diagnostic命令来查看隧道的出接口。
