Networking Requirements

As shown in Figure 4-57, the primary CR-LSP is along the path LSRA -> LSRB -> LSRC -> LSRD, and the link between LSRB and LSRC needs to be protected by FRR.

A bypass CR-LSP is set up along the path LSRB -> LSRE -> LSRC. LSRB functions as the PLR and LSRC functions as the MP.

The primary and bypass MPLS TE tunnels need to be set up by using explicit paths. RSVP-TE is used as the signaling protocol.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Assign an IP address to each interface, enable IS-IS globally, configure the NET, and enable IS-IS on each interface including the loopback interface.

  2. Configure an ID for each LSR and globally enable MPLS, MPLS TE, RSVP-TE, and CSPF on each node and interface. Enable IS-IS TE and change the cost type.

  3. 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 dynamic signaling protocol RSVP-TE for the tunnel interface.

  4. Enable TE FRR on the interface of the primary tunnel on the ingress node.

  5. Create a tunnel interface on the ingress node LSRB of the bypass tunnel of the protected link, set the IP address, tunnel protocol, destination IP address, tunnel ID, and RSVP-TE for the tunnel interface, and specify the interface of the protected link.

Procedure

  1. Assign IP addresses to interfaces.

    # Configure LSRA. The configurations of LSRB, LSRC, LSRD, and LSRE are similar to the configuration of LSRA, and are not mentioned here. 

    <Huawei> system-view
[Huawei] sysname LSRA
[LSRA] interface gigabitethernet 1/0/0
[LSRA-GigabitEthernet1/0/0] ip address 172.1.1.1 255.255.255.0
[LSRA-GigabitEthernet1/0/0] quit
[LSRA] interface loopback 1
[LSRA-LoopBack1] ip address 1.1.1.9 255.255.255.255
[LSRA-LoopBack1] quit

  2. Configure IS-IS to advertise routes.

    # Configure LSRA. The configurations of LSRB, LSRC, LSRD, and LSRE are similar to the configuration of LSRA, and are not mentioned here. 

    [LSRA] isis 1
[LSRA-isis-1] network-entity 00.0005.0000.0000.0001.00
[LSRA-isis-1] is-level level-2
[LSRA-isis-1] quit
[LSRA] interface gigabitethernet 1/0/0
[LSRA-GigabitEthernet1/0/0] isis enable 1
[LSRA-GigabitEthernet1/0/0] quit
[LSRA] interface loopback 1
[LSRA-LoopBack1] isis enable 1
[LSRA-LoopBack1] quit

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

    [LSRA] display ip routing-table

  3. Configure basic MPLS functions and enable MPLS TE, CSPF, RSVP-TE, and IS-IS TE.

    # Configure LSRA. The configurations of LSRB, LSRC, LSRD, and LSRE are similar to the configuration of LSRA, and are not mentioned here. CSPF needs to be enabled only on the ingress node of the primary tunnel (LSRA) and the ingress node LSRB of the bypass tunnel (LSRB); CSPF does not need to be enabled on LSRC, LSRD, or LSRE.

  4. On LSRA, create an MPLS TE tunnel for the primary CR-LSP.

    # Configure the explicit path of the primary CR-LSP.

    [LSRA] explicit-path pri-path
[LSRA-explicit-path-pri-path] next hop 172.1.1.2

    # Configure the MPLS TE tunnel interface of the primary CR-LSP.

    After the configurations are complete, run the display interface tunnel command on LSRA. You can see that the status of Tunnel0/0/1 is Up.

    [LSRA] display interface tunnel 0/0/1

    After the configurations are complete, run the display interface tunnel command on LSRB. You can see that the status of Tunnel0/0/2 is Up.

    Run the display mpls lsp command on all the LSRs. You can view the LSP entry and that two LSPs pass through LSRB and LSRC.

    NOTE:

    Run the display mpls te tunnel-interface command to view detailed information about tunnel interfaces. You can view two CR-LSPs in Up state. This is because FRR establishes a new LSP by using the make-before-break mechanism. The original LSP is deleted only after the new LSP is established successfully.
