Example for Configuring Auto TE FRR
Networking Requirements
As shown in Figure 4-58, a primary tunnel is set up by using the explicit path LSRA -> LSRB -> LSRC -> LSRD. A bypass tunnel is set up on the ingress node LSRA to protect LSRB, and a bypass tunnel is set up on the transit node LSRB to protect the link between LSRB and LSRC.
Configuration Roadmap
The configuration roadmap is as follows:
Assign an IP address to each interface and configure OSPF to ensure that there are reachable routes between LSRs.
Configure an ID for each LSR and globally enable MPLS, MPLS TE, RSVP-TE, CSPF on each node and interface, and enable OSPF TE.
Enable auto TE FRR in the MPLS view of the ingress node of the primary tunnel and configure node protection. Enable auto TE FRR in the MPLS view of the ingress node of the bypass tunnel and configure link protection.
On the ingress node of the primary tunnel, create a tunnel interface, and specify the IP address, tunneling protocol, destination IP address, tunnel ID, and RSVP-TE for the tunnel interface.
Enable TE FRR on the tunnel interface of the ingress node of the primary tunnel.
Procedure
- Assign an IP address to each interface and configure OSPF.

After the configurations are complete, run the display ip routing-table command on each LSR. You can see that the LSRs learn the routes to Loopback1 of each other. The display on LSRA is used as an example.
