Example for Setting Up CR-LSPs Using CR-LSP Attribute Templates
Networking Requirements
As shown in Figure 1, an MPLS TE tunnel is set up between LSRA and LSRC. The primary path of the tunnel is LSRA -> LSRB -> LSRC. When the primary CR-LSP fails, traffic must be switched to a backup CR-LSP.
LSRA needs to set up multiple MPLS TE tunnels to meet service requirements. The network administrator wants to simplify the MPLS TE tunnel configuration.
In this scenario, to avoid loops, ensure that all connected interfaces have STP disabled and connected interfaces are removed from VLAN 1. If STP is enabled and VLANIF interfaces of switches are used to construct a Layer 3 ring network, an interface on the network will be blocked. As a result, Layer 3 services on the network cannot run normally.
Configuration Roadmap
The configuration roadmap is as follows:
Assign IP addresses to interfaces and configure OSPF to ensure that public network routes between the nodes are reachable.
Configure LSR IDs for the nodes, enable MPLS, MPLS TE, RSVP-TE, and CSPF on the LSRs globally and on their interfaces, and enable OSPF TE on the LSRs.
Use CR-LSP attribute templates to simplify the configuration. Configure different attribute templates for the primary CR-LSP, hot-standby CR-LSP, and ordinary backup CR-LSP.
On the ingress node of the primary tunnel, create a tunnel interface, configure the tunnel IP address, tunneling protocol, destination IP address, tunnel ID, and RSVP-TE signaling protocol for the tunnel interface, and then apply the corresponding CR-LSP attribute template to set up the primary CR-LSP.
Configure hot-standby and ordinary backup CR-LSPs on the ingress node of the primary tunnel. In this way, traffic can be switched to the backup CR-LSP when the primary CR-LSP fails. Apply the CR-LSP corresponding attribute template to create the backup CR-LSP.
Procedure
- Assign IP addresses to interfaces and configure OSPF on
the LSRs.
# Configure LSRA. Assign IP addresses to interfaces of LSRB, LSRC, LSRE, and LSRF according to Figure 1. The configurations on these LSRs are similar to the configuration on LSRA, and are not mentioned here.

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