Example for Configuring Bit-Error-Triggered Protection Switching on an NG MVPN

This section provides an example for configuring bit-error-triggered protection switching in an NG MVPN scenario.

Networking Requirements

In an NG MVPN scenario, multicast data flows must be transmitted on a link that has no or few bit errors because even low bit error rates may cause black screen, erratic display, or frame interruption. You can configure IS-IS bit error detection and bit-error-triggered protection switching, allowing the mLDP tunnel end to select a new outbound interface if the interface in use is suffering a high bit error rate.

If no bit error occurs on the links, the primary NG MVPN mLDP link is Leaf-P1-Root. If bit errors occur on interface 2 of the leaf node, the link Leaf-P2-Root becomes the primary one. P2 receives the bit error rate information sent by the leaf node, triggering the mLDP tunnel to select interface 1 as the downstream outbound interface. In this example, the advanced IS-IS topology is configured across the entire network, and the primary LSP tunnel of MPLS mLDP is created in the advanced topology.

Interfaces 1 through 4 in this example represent GE 0/1/0, GE 0/1/1, GE 0/1/2, and GE 0/1/3, respectively.

Figure 1 Configuring bit-error-triggered protection switching on an NG MVPN

Configuration Roadmap

The configuration roadmap is as follows:

  1. Bind the interfaces connecting P1 and the leaf node to Eth-Trunk 1. Bind the interfaces connecting P2 and the root node to Eth-Trunk 1.

  2. Establish a VLL PW between P1 and the root node.

  3. Configure the interfaces Eth-Trunk 1.1 of the leaf node and P2 as AC interfaces for the access to the root node and P1.

  4. Configure an IP address for each interface and routing protocols, so that all devices can communicate at the network layer. This example uses the advanced topology of IS-IS routes.

  5. Establish an NG MVPN neighbor relationship between the root and leaf nodes. Configure the leaf node as the mLDP leaf node, and the root node as the mLDP root node.

  6. Enable BFD globally, enable IS-IS bit error detection on the logical direct interfaces Eth-Trunk 1.1 of the leaf node and P2. Enable bit-error-triggered IGP route switching on the interfaces Eth-Trunk 1 of the leaf node and P1.

Data Preparation

To complete the configuration, you need the following data:

  • IP address of each interface as listed in Figure 1

  • IS-IS instance ID: 1; advanced topology name: advancedtop; network entity names of P1, root node, leaf node, and P2: 10.0000.0000.0001.00, 10.0000.0000.0002.00, 10.0000.0000.0003.00, and 10.0000.0000.0004.00, respectively

  • VPN instance name: vpna; RD and vpn-target: 100:100

  • MPLS L2VPN VSI name: VSI1; VSI ID: 1112

  • BGP instance ID: 100

  • VLAN ID of Eth-Trunk 1.1: 100

Procedure

  1. Bind the interfaces connecting P1 and the leaf node to Eth-Trunk 1. Bind the interfaces connecting P2 and the root node to Eth-Trunk 1.

    # Bind GE 0/1/1 and GE 0/1/2 of the leaf node to Eth-Trunk 1.

  2. Configure the sub-interfaces Eth-Trunk 1.1 on the leaf node and P2. Configure IP addresses for the interfaces according to Figure 1. For details, see the configuration files.
  3. Establish a VLL PW between P1 and the root node.

    # Configure the VLL on P1.

  4. Configure the sub-interfaces Eth-Trunk 1.1 on the leaf node and P2. Configure the sub-interfaces as AC interfaces for the access to P1 and the root node.

    # Configure the AC interface on P1.

    [~P1] interface Eth-Trunk 1.1

[*Root-Eth-Trunk1.1] commit

  5. The sub-interfaces of the leaf node and P2 reside on the same network segment. Run the ping 10.1.3.2 command on the leaf node. The ping operation succeeds.

  6. Enable IS-IS on the interfaces of P1, P2, root node, and leaf node. Bind the interfaces to the advanced IS-IS topology. On the leaf node, set the cost values of Eth-Trunk 1.1 and GE 0/1/0 to 100 in the advanced IS-IS topology, so that P1 is preferentially selected as the next hop on the route from the leaf node to the root node 4.4.4.4. Enable LDP and mLDP globally on the four devices. Enable LDP on interfaces. For details, see the configuration files. Configure an advanced IS-IS topology across the entire network. Create the primary LSP of MPLS mLDP in the advanced topology.

P2 learns the bit error rate through IGP association. mLDP excludes Eth-Trunk 1.1 from the outbound interface selection list and selects GE 0/1/0 as the outbound interface.
