4. Create a tunnel. You can configure an MPLS TE tunnel using static CR-LSP, a dynamic signaling
protocol RSVP TE or CR-LDP. Configuring an MPLS TE tunnel through a static CR-LSP requires no
tunnel constraints and involves no TE extension of any IGP or CSPF calculation. Configuring a
tunnel through a dynamic signaling protocol is more complicated. The dynamic signaling protocol
can dynamically adjust the path of the TE tunnel according to the network performance, and
supports advanced features such as backup and Fast Reroute (FRR).
5. Configure protection (optional). MPLS TE Management allows you to configure a backup path and
FRR protection for a network node or link. Once the node or link fails, traffic is rerouted to the
backup path for forwarding.
6. Configure traffic access. Data can be forwarded along the tunnel only after you introduce the
traffic to the tunnel.
7. View the MPLS TE network topology (optional). You can zoom in or out of the topology view,
display the vertical view of the topology, display the TE link information, and filter links by tunnel
and by administrative group.
Configuring traffic engineering in MPLS TE
Management
MPLS TE Management works with the devices that form the basis of your network infrastructure. After you
install and deploy MPLS TE Management through the H3C Intelligent Deployment Monitoring Agent, you
can launch IMC in your browser, access MPLS TE Management, and work with supported devices.
You need to make sure that the devices have been imported into IMC basic platform and that MPLS and
MPLS TE basic capabilities are enabled on your devices before you can manage your TE networks using
MPLS TE Management. The configuration instructions for enabling MPLS and MPLS TE basic capabilities
may differ from device to device. For detailed configuration instructions, see the configuration guide of
your device.
Configuring MPLS basic capabilities
Before you configure MPLS basic capabilities, complete the following tasks:
• Configure link layer protocols to ensure the connectivity at the link layer.
• Assign IP addresses to interfaces, making all neighboring nodes reachable at the network layer.
• Configure static routes or an IGP protocol, ensuring that LSRs can communicate with each other at
the network layer.
Configuring MPLS TE basic capabilities
After configuring the basic capabilities, you need to make additional configurations in order to use MPLS
TE depending on the actual requirements.
