Scenario Analysis
You can create two tunnels through a dynamic signaling protocol: tunnel A (Router A -> Router B
-> Router C) and tunnel B (Router A -> Router D -> Router C). The two tunnels have the same headend
and tailend. Thus you can configure tunnel B as the CR-LSP backup tunnel of tunnel A. Note: You
cannot configure CR-LSP backup for MPLS TE tunnels configured through the static CR-LSP protocol.
Operation Procedure
1. Import devices to the MPLS TE manager.
a.
Select the Service tab, and then select ResourceDevice from the navigation tree to enter
the MPLS TE device management page.
Click Import Device to import devices. For details, refer to Resource Management.
2. Configure dynamic MPLS TE tunnels.
a.
Select the Service tab, click MPLS TE Tunnel Management in the navigation tree to enter
the MPLS TE tunnel list page.
b. Click Add to perform dynamic tunnel configuration. For details, refer to MPLS TE Tunnel
Management.
3. Configure CR-LSP backup.
a.
Select the Service tab, and then click Protection Management in the navigation tree to
enter the protection management page.
b. Change the backup type and click the corresponding icon of the record to deploy the
configuration to the device.
Configure link protection for tunnels
Application Scenario
A company has five offices, office A through office E, which are connected with one another
through networks. It is required to protect the link between office B and office C, so that data
packets can be switched to another path quickly when the link fails, and switched back to the
original link after the original link resumes. Assume that the routers are reachable to each other
after being configured with IS-IS or OSPF and are properly configured with basic MPLS and MPLS
TE capabilities, as shown in the following figure:
•
Router A: LSR ID address is 1.1.1.1/32; address of Ethernet 1/0 is 2.1.1.1/24.
•
Router B: LSR ID address is 2.2.2.2/32; address of Ethernet 1/0 is 2.1.1.2/24; address of
Ethernet 1/1 is 3.2.1.1/24; address of POS 5/0 address is 5.2.1.1/24.
•
Router C: LSR ID address is 3.3.3.3/32; address of Ethernet 1/0 is 4.2.1.1/24; address of
Ethernet 1/1 is 3.2.1.2/24; address of POS 5/0 is 6.2.1.1/24.
