配置热备份CR-LSP动态带宽功能示例
组网需求
图4-56为MPLS VPN网络。要求从LSRA上建立一条TE隧道，目的地址为LSRC，并配置CR-LSP热备份（hot-standby）和逃生路径（best-effort）。其中：
主CR-LSP的路径为LSRA→LSRB→LSRC；
备份CR-LSP的路径为LSRA→LSRD→LSRC；
逃生路径为LSRA→LSRD→LSRB→LSRC。
当主CR-LSP故障时，流量切换到备份CR-LSP；当主CR-LSP故障恢复，延时15秒后再进行流量回切。如果主、备CR-LSP都故障，触发建立逃生路径，使流量切换到逃生路径上。
由于客户的带宽资源比较紧张，如果配置热备份CR-LSP，会降低客户的带宽使用效率，提高客户的成本。因为热备份CR-LSP占用的这部分带宽只有在流量切换到热备份时才会使用。
此时可以选择在入节点使能热备份CR-LSP动态带宽功能来解决以上的问题：
在主CR-LSP正常使用时，热备份CR-LSP将不占用带宽，节约了客户的带宽资源。
当主CR-LSP故障后，流量将切换到热备份CR-LSP上，此时隧道将采取尽力而为的方式进行流量传输。然后系统会采用Make-before-break机制并按照用户期望的带宽重建一条CR-LSP。当新的热备份CR-LSP建立成功后，流量就切换到新的CR-LSP上，然后将带宽值为0的热备份CR-LSP删除。
操作步骤
- 配置各接口的IP地址，并配置OSPF
# 配置LSRA。LSRB、LSRC和LSRD的配置与LSRA类似，不再赘述。
<Huawei> system-view [Huawei] sysname LSRA [LSRA] interface gigabitethernet 1/0/0 [LSRA-GigabitEthernet1/0/0] ip address 172.1.1.1 255.255.255.0 [LSRA-GigabitEthernet1/0/0] quit [LSRA] interface gigabitethernet 2/0/0 [LSRA-GigabitEthernet2/0/0] ip address 172.5.1.1 255.255.255.0 [LSRA-GigabitEthernet2/0/0] quit [LSRA] interface loopback 1 [LSRA-LoopBack1] ip address 1.1.1.9 255.255.255.255 [LSRA-LoopBack1] quit [LSRA] ospf 1 [LSRA-ospf-1] area 0 [LSRA-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0 [LSRA-ospf-1-area-0.0.0.0] network 172.1.1.0 0.0.0.255 [LSRA-ospf-1-area-0.0.0.0] network 172.5.1.0 0.0.0.255 [LSRA-ospf-1-area-0.0.0.0] quit [LSRA-ospf-1] quit
配置完成后，在各节点上执行display ip routing-table命令，应可以看到相互之间都学到了到对方Loopback1的路由。
- 配置MPLS基本能力，使能MPLS TE、RSVP-TE和CSPF
在各节点的MPLS视图和接口视图下使能MPLS TE、RSVP-TE。在入节点使能CSPF功能，在主CR-LSP和热备份CR-LSP经过的所有节点出接口配置链路最大可预留带宽为100Mbit/s，BC0带宽为100Mbit/s。
# 配置LSRA。LSRB、LSRC和LSRD的配置与LSRA类似，不再赘述。其中，只需在主隧道和旁路隧道的入节点上使能CSPF。即只需在LSRA上使能CSPF，LSRB、LSRC和LSRD上无需使能CSPF。带宽相关配置只需要在LSRB的GE2/0/0接口和LSRD的GE1/0/0接口进行配置即可。

- 配置OSPF TE
# 配置LSRA。LSRB、LSRC和LSRD的配置与LSRA类似，不再赘述。

- 配置主、备CR-LSP使用的显式路径
# 在LSRA上配置主CR-LSP使用的显式路径。
[LSRA] explicit-path pri-path [LSRA-explicit-path-pri-path] next hop 172.1.1.2 [LSRA-explicit-path-pri-path] next hop 172.2.1.2 [LSRA-explicit-path-pri-path] next hop 3.3.3.9 [LSRA-explicit-path-pri-path] quit
# 在LSRA上配置备份CR-LSP使用的显式路径。

完成以上配置后，可在LSRA上执行命令查看已经配置的显式路径。
[LSRA] display explicit-path pri-path Path Name : pri-path Path Status : Enabled 1 172.1.1.2 Strict Include 2 172.2.1.2 Strict Include 3 3.3.3.9 Strict Include [LSRA] display explicit-path backup-path Path Name : backup-path Path Status : Enabled 1 172.5.1.2 Strict Include 2 172.3.1.1 Strict Include 3 3.3.3.9 Strict Include
- 配置隧道接口
# 在LSRA上创建Tunnel接口，指定显式路径，配置隧道的CT0带宽为10Mbit/s。

完成以上配置后，在LSRA上执行display mpls te tunnel-interface tunnel 0/0/1命令，可发现主CR-LSP、备份CR-LSP建立成功。
