Example for Connecting an E-Trunk to a VPLS Network

Overview

Enhanced Trunk (E-Trunk) is an extension to LACP (a link aggregation protocol for a single device) and implements link aggregation among multiple devices. E-Trunk achieves device-level link reliability but not card-level link reliability.

When a CE is dual-homed to a VPLS, VLL, or PWE3 network, an E-Trunk can be configured to protect the links between the CE and PEs and implement backup between PEs. If no E-Trunk is configured, a CE can be connected to only one PE using an Eth-Trunk. If the Eth-Trunk or the PE fails, the CE cannot communicate with the PE. After the E-Trunk is used, the CE can be dual-homed to two PEs to implement backup.

Configuration Notes

  • Devices must use link aggregation in LACP mode.

  • In Figure 1, the E-Trunk configuration on PE1 and PE2 must be the same. The Eth-Trunks between PE1 and CE1 and between PE2 and CE1 must use the same rate and duplex mode (key values must be the same) and join the same E-Trunk. After the Eth-Trunks are added to the E-Trunk, ensure that the LACP priorities and system IDs of PE1 and PE2 are the same. On CE1, interfaces directly connected to PE1 and PE2 must be added to the same Eth-Trunk. The Eth-Trunk can have a different Eth-Trunk ID from that on the PEs. For example, the CE is configured with Eth-Trunk 20, while both PEs are configured with Eth-Trunk 10.

  • You must specify an IP address (loopback address recommended) for each PE to ensure Layer 3 connectivity. Ensure that the peer IP address of a PE is the local IP address of the other PE.

  • The E-Trunk must be bound to a BFD session.

  • You must set the same protocol packet password for PE1 and PE2.

  • For applicable product models and versions, see Applicable Product Models and Versions.

    For details about software mappings, visit Hardware Query Tool and search for the desired product model.

Networking Requirements

If no E-Trunk is configured, a CE can be connected to only one PE using an Eth-Trunk. If the Eth-Trunk or the PE fails, the CE cannot communicate with the PE. After an E-Trunk is configured, the CE can be dual-homed to PEs. E-Trunk achieves device-level link reliability but not card-level link reliability.

In Figure 1, CE1 is connected to PE1 and PE2 using two Eth-Trunks in LACP mode and is dual-homed to a VPLS network.

Initially, CE1 communicates with CE2 on the VPLS network through PE1. If PE1 or the Eth-Trunk between CE1 and PE1 fails, CE1 cannot communicate with CE2. To prevent service interruption, configure an E-Trunk on PE1 and PE2. When communication between CE1 and PE1 fails, traffic is switched to PE2 so that CE1 can communicate with CE2 through PE2. When PE1 or the Eth-Trunk between CE1 and PE1 recovers, traffic is switched back to PE1.

The E-Trunk implements backup of link aggregation groups (LAGs) between PE1 and PE2 and therefore improves network reliability.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an E-Trunk.

    • Create Eth-Trunks in LACP mode between CE1 and PE1 and between CE1 and PE2. Add member interfaces to the Eth-Trunks.

    • Create an E-Trunk on PE1 and PE2 and add the two Eth-Trunks in LACP mode to the E-Trunk.

    • Set E-Trunk parameters:

      • E-Trunk priority

      • LACP system ID and LACP priority of the E-Trunk

      • Interval at which Hello packets are sent

      • Time multiplier for detecting Hello packets

      • IP addresses of the local and remote ends

    • Bind the E-Trunk to a BFD session.
  2. Configure CE1 to connect to the VPLS network as follows:

    • Configure a routing protocol on the backbone network to implement the interworking between devices.

    • Configure basic MPLS functions and LDP.

    • Enable MPLS L2VPN on PEs.

    • Configure a VSI and specify LDP as the signaling protocol.

    • Create Eth-Trunk sub-interfaces and bind the VSI to the sub-interfaces.

Procedure

  1. Configure VLANs and IP addresses on the PW-side interfaces according to Figure 1. Configure a routing protocol on the backbone network to implement the interworking between devices. OSPF is used in this example.

[PE3-ospf-1-area-0.0.0.0] quit
[PE3-ospf-1] quit

    After the configuration is complete, PE1, PE2, and PE3 use OSPF to discover IP routes to each other's Loopback1 interface, and can ping one another. Run the display ip routing-table command on PE1, PE2, and PE3 to determine whether the PEs have learned the routes to one another.

    • The AC-side interface and PW-side interface of a PE cannot be added to the same VLAN; otherwise, a loop may occur.
    • When configuring OSPF, configure PE1, PE2, and PE3 to advertise 32-bit loopback addresses.

  2. Configure Eth-Trunks in LACP mode on user-side switch CE1, PE1, and PE2, and add member interfaces to the Eth-Trunks. Configure Layer 2 forwarding on CE1.

[PE3-GigabitEthernet1/0/3.1] l2 binding vsi ldp1 //Bind GE1/0/3.1 to the VSI ldp1.
[PE3-GigabitEthernet1/0/3.1] quit

  7. Verify the configuration.

    • Run the display eth-trunk command on CE1 to check the Eth-Trunk configuration.

    • Run the display e-trunk command to check information about the E-Trunk.

      # Check information about E-Trunk 1 on PE1.
