Scenario Analysis
Configure dynamic MPLS TE tunnel Router A -> Router B -> Router C -> Router D through a dynamic
signaling protocol (such as RSVP-TE) and reserve resources on the devices along the tunnel, so that
data from Route A to Router D is always serviced.
Operation Procedure
1. Import devices to the MPLS TE manager.
a.
Select the Service tab, select ResourceDevice from the navigation tree to enter the MPLS
TE device management page.
b. Click Import Device to import devices. For configuration details, refer to Resource
Management.
2. Configure an explicit path.
a.
Select the Service tab, and then click Explicit Path Management in the navigation tree to
enter the explicit path management page.
b. Click Add to perform explicit path configuration. For details, refer to Explicit Path
Management.
3. Configure a dynamic MPLS TE tunnel.
a.
Select the Service tab, and then click MPLS TE Tunnel Management in the navigation tree
to enter the MPLS TE tunnel list page.
b. Click Add to enter the page for adding an MPLS TE tunnel.
c. Type the basic configuration information, select RSVP-TE from the Protocol drop-down
list, and then click Next to enter the page for adding a dynamic tunnel.
d. Type the basic attributes of the tunnel and click Next to enter the page for configuring
the routing policy.
e. Type the routing policy information of the tunnel and click Next to enter the page for
configuring advanced attributes.
f. Type the advanced attributes of the tunnel and click Finish to enter the summary page.
g. Click Finish.
Configure CR-LSP backup for tunnels
Application Scenario
A company has four offices, office A through office D, which are connected with one another
through networks. It is required to backup the forwarding of service data from office A to office
C. 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; address of
POS 5/1 is 5.2.1.1./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.
•
Router C: LSR ID address is 3.3.3.3/32; address of Ethernet 1/0 is 3.2.1.2/24; address of
POS 5/1 is 4.2.1.1/24.
•
Router D: LSR ID address is 4.4.4.4/32; address of POS 5/0 is 5.2.1.2/24; address of POS
5/1 is 4.2.1.2/24.
