In this manner, when the primary CR-LSP becomes faulty, traffic can be switched to the hot-
standby CR-LSP. Traffic is switched back to the primary CR-LSP 15 seconds after the fault on
the primary CR-LSP is rectified.
But if the hotstandby CR-LSP is faulty and therefore is unable to carry the traffic that is switched
from the primary CR-LSP, the hotstandby CR-LSP needs to be detected. NQA LSP Trace can
be used to detect the connectivity of the hotstandby CR-LSP. This function can detect the
connectivity of the hotstandby CR-LSP and its performance in real time. This helps detect and
identify faults on the hotstandby CR-LSP.

Data Preparation
To complete the configuration, you need the following data:
Issue 01 (2012-03-15)
OSPF is configured on Switch A, Switch B, Switch C, and Switch D to enable them to learn
the 32-bit host addresses of the loopback interfaces from each other.
MPLS, MPLS TE, and MPLS RSVP-TE are enabled on Switch A, Switch B, Switch C,
and Switch D.
MPLS, MPLS TE, and MPLS RSVP-TE are enabled on the POS interfaces connected to
Switch A, Switch B, and Switch C. Then, a TE tunnel is set up from Switch A to Switch
C.
The primary CR-LSP is Switch A-Switch B-Switch C.
The hotstandby CR-LSP is Switch A-Switch D-Switch C.
