Configuration Roadmap
The configuration roadmap is as follows:

6.
Before establishing a unidirectional RSVP-TE tunnel, you must run the label advertise non-
null command to enable the egress of the unidirectional tunnel to allocate a non-null label to the
penultimate hop. Otherwise, bit-error-triggered RSVP-TE tunnel switching cannot take effect.
Data Preparation
To complete the configuration, you need the following data:

Configure an IP address and a routing protocol for each interface so that all nodes can
communicate at the network layer. This example uses Open Shortest Path First (OSPF) as
the routing protocol.
Enable Bidirectional Forwarding Detection (BFD) globally on each node.
Configure a bidirectional RSVP-TE tunnel with TE hot-standby protection between the
UPE and SPE.
Configure BFD for CR-LSP for the bidirectional RSVP-TE tunnel.
Enable bit-error-triggered RSVP-TE tunnel switching for the bidirectional RSVP-TE
tunnel and set the thresholds for bit-error-triggered protection switching and revertive
switching.
On each tunnel interface, specify the other unidirectional tunnel as the reverse tunnel of
the current unidirectional tunnel.
