MTR（Multi-Topology Routing，多拓扑路由）是指将一个物理拓扑划分成多个逻辑的拓扑，这些逻辑的拓扑可能是交叉或者重叠的。不同拓扑运行各自的路由计算，实现网络的互通。
例如，IS-IS MTR就是指在一个IS-IS自治域内运行多个独立的IP拓扑，例如IPv4拓扑和IPv6拓扑，而不是将它们视为一个集成的单一拓扑。这有利于IS-IS在路由计算中根据实际组网情况来单独考虑IPv4和IPv6网络。
图1-1 MTR工作机制
如图1-1所示，可以根据需要对全局拓扑进行划分，分为多个子拓扑，这样不同的流量就可以走不同的拓扑。例如，语音流可以走子拓扑A，视频流可以走子拓扑B。
对于子拓扑A而言，Router B并不存在；而对于子拓扑B而言，它认为Router A和Router D之间，以及Router B和Router C之间并没有可用的链路相连。每一个单独的拓扑都根据路由协议计算出自己的路由，属于本拓扑的流量则根据本拓扑的路由表进行转发。
· IS-IS MTR：详细情况请参见“三层技术-IP路由配置指导”中的“IS-IS”和“IPv6 IS-IS”。
· 静态路由支持MTR：详细情况请参见“三层技术-IP路由配置指导”中的“静态路由”。
表1-1 配置MTR
|
操作 |
命令 |
说明 |
|
进入系统视图 |
system-view |
- |
|
进入拓扑地址族视图 |
address-family ipv4 |
- |
|
创建拓扑，并进入拓扑视图 |
multiple-topology topology-name |
必选 缺省情况下，没有创建任何拓扑 |
|
配置拓扑的访问控制列表号 |
acl acl-number |
必选 |
|
配置拓扑支持的最大路由数 |
routing-table limit number { warn-threshold | simply-alert } |
可选 |
|
退回系统视图 |
quit |
- |
|
进入接口视图 |
interface interface-type interface-number |
- |
|
将接口与指定拓扑进行关联 |
multiple-topology topology-name enable |
必选 缺省情况下，接口不关联到任何拓扑 |
在完成上述配置后，在任意视图下执行display命令可以显示配置后MTR的运行情况，用户可以通过查看显示信息验证配置的效果。
表1-2 MTR显示和维护
|
命令 |
|
|
显示拓扑信息 |
display multiple-topology [ multiple-topology-name ] [ | { begin | exclude | include } regular-expression ] |
