Configuring imported devices
This function helps you configure the CR-LSP arbitrage policy, configure traffic forwarding parameters, set
the FRR scanning interval, configure auto bandwidth adjustment, enable or reset auto bandwidth
adjustment, and enable MPLS TE for devices that are already imported to the MPLS TE Management. You
can decide which configurations to make according to real needs.
To configure an imported device:
1. Click Service > MPLS TE Manager from the tabular navigation system on the top of the IMC main
page.
2. Click Resource Mng > Device Mng in the left navigation tree.
3. In the Device List section of the page, click the Operation icon on the same line as the device
that you want to configure. A list appears, as shown in Figure 39 .

4. In the list, you can:
a. Select the Configure CR-LSP Arbitrage Policy option to configure the CR-LSR arbitrage policy
for the device.
CR-LSP Arbitrage Policy—When CSPF is calculating the shortest path to the end of a tunnel, if
multiple paths are present with the same metric value, only one is selected according to the
CR-LSP arbitrage policy. CR-LSP arbitrage policy prioritizes the selection in the following order:
Min Bandwidth (path with the lowest bandwidth usage ratio is preferred), Max Bandwidth
(path with the highest bandwidth usage ratio is preferred), and Random (one of the remaining
paths is picked at random. This rule tends to place an equal number of LSPs on each link,
regardless of the available bandwidth ratio).
b. Select the Configure Traffic Forwarding Parameters option to configure the invalid link timer
and the link metric type for the device. The invalid link timer starts once a link goes down. If IGP
removes or modifies the link before the timer expires, CSPF is informed of the change and it
then updates information about the link in TEDB and stops the timer. If IGP does not remove or
