MPLS TE Management workflow
To use MPLS TE Management effectively in your network environment, it is helpful to understand the
recommended workflow, as shown in
Figure 35 .
Figure 35 MPLS TE Management workflow
Workflow tasks are summarized as follows:
1. Import and configure network devices, such as routers, switches, and other devices that support
MPLS TE. To ensure that a device can be imported to the MPLS TE system properly, perform the
following operations on the device:
a. Configure the loopback address and the LSR ID IP address.
b. Configure a static route or an IGP protocol (such as OSPF) to make sure that the device is
reachable on the network and the LSR ID of the device is advertised to the network through the
routing protocol.
c. Make sure that MPLS TE basic capabilities have been enabled on devices. Commands for
enabling MPLS TE basic capabilities differ from device to device, for detailed information
about how to enable MPLS TE basic capabilities on your device, see the configuration guide of
the device.
2. Adjust device configurations, such as the device CR-LSP arbitrage policy and the traffic forwarding
parameters.
3. Configure explicit path (optional). This step is not necessary in static CR-LSP tunnel configuration,
and is optional in dynamic tunnel configuration. An explicit path consists of a series of nodes and
is used to restrict the path that a tunnel is to pass. When configuring a tunnel, you can bind a
configured explicit path.
