Example for Configuring VPLS PW Redundancy in an HVPLS Scenario

This section provides an example for configuring VPLS PW redundancy in an HVPLS scenario.

Networking Requirements

As shown in Figure 1, access and aggregation rings are deployed on the MAN. End-to-end LDP LSPs are deployed between PEs. An HVPLS network is established among the UPE, SPEs, and NPEs to carry multicast services, such as IPTV, on the MAN. Upstream traffic on the MAN is aggregated on the NPEs for transmission to the egress. CE2 is deployed at the egress of the MAN to assign IP addresses to users and provide IPTV services.

The service provider requires that multicast services be reliably transmitted even if an NPE or a PW fails, or an AC of CE2 fails. The service provider also requires that the deployed features be not vendor-specific and consume as less bandwidth as possible.

To meet the preceding requirements, configure VPLS PW redundancy in the HVPLS scenario. Connect the UPE to SPE1 and SPE2 using two PWs and configure the two PWs to work in backup mode. Connect the SPEs and NPEs using hub PWs. Configure an Eth-Trunk between CE2 and NPE1 and between CE2 and NPE2. Configure an E-Trunk between the NPEs and add the two Eth-Trunks to the E-Trunk. This configuration enhances network reliability with non-vendor-specific features. Meanwhile, the HVPLS networking reduces required PWs and bandwidth.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IP address and a routing protocol for each interface so that all PEs can communicate at the network layer. This example uses OSPF as the routing protocol.

  2. Configure MPLS and public network tunnels.

    In this example, LDP LSPs are used as tunnels between PEs.

    • Enable MPLS and MPLS LDP globally on each PE.
    • Enable MPLS on each PE interface.
    • Enable MPLS LDP on the ingress and egress PE interfaces of each LDP LSP.

  3. Configure PWs on the HVPLS network.

    • Enable MPLS L2VPN on each PE.
    • Create a VSI on each PE.
    • Specify the VSI peer on each PE. Configure two spoke PWs between the UPE and SPEs. Configure four hub PWs between the SPEs and NPEs.

  4. Add the PWs between the UPE and SPEs to a PW protection group for the two PWs to work in backup mode.

    • Configure a PW protection group on the UPE.
    • Configure the master/slave PW redundancy mode.
    • Add the PWs to the PW protection group and specify the priorities of the PWs.
    • Set the revertive switching delay to 60s.

  5. Configure CE1 and CE2 to access the HVPLS network so that CE1 and CE2 can communicate.

    • Connect CE2 to the NPEs over two Eth-Trunks and add the Eth-Trunks to the E-Trunk configured between the NPEs.
    • Connect CE1 to the UPE over a VLAN.

  6. Configure BFD for PW to detect the faults of the primary PW, so that services can be immediately switched to the secondary PW if the primary PW fails.

    • Enable BFD globally on both ends of the primary PW.
    • Establish a BFD session between the end PEs of the primary PW.

Data Preparation

To complete the configuration, you need the following data.

  • IP address, OSPF process ID (1), and OSPF area ID (0) of each interface

  • LSR ID of each node and the names and numbers of the interfaces on which LDP sessions are to be set up

  • VSI name (vsi1), member discovery mode (static), VSI signaling type (LDP), VSI ID (1), VSI peer IP address, and AC interface types and numbers

  • PW protection group name (vsi1), PW redundancy mode (master), revertive switching mode (delayed switching), revertive switching delay (60s), and PW priorities (1 and 2)

  • E-Trunk ID (1), system ID (0000-0000-0001), LACP priority (1), Eth-Trunk ID (10), E-Trunk priorities (150 and default 100), local and peer IP addresses, VLAN ID (10), and VLAN encapsulation type (dot1q)

  • BFD configuration name, peer IP address of the PW tracked by BFD, local interface name and number, and local and remote BFD session discriminators

Procedure

  1. Configure an IP address and a routing protocol for each interface on the backbone network so that PEs can communicate at the network layer.

    This example uses OSPF. For configuration details, see Configuration Files in this section.

    After the configuration is complete, run the display ip routing-table command on the UPE, SPEs, and NPEs to verify that the UPE, SPEs, and NPEs have learned each other's loopback interface IP address.

  2. Configure MPLS and public network tunnels.

    This example uses LDP LSPs as public network tunnels. For configuration details, see Configuration Files in this section.

    After the configuration is complete, run the display mpls ldp session command on the UPE, SPEs, and NPEs. If Status of the peer relationship between the UPE and SPE or between the NPE and SPE is Operational, the peer relationship has been established. Run the display mpls lsp command to check that LSPs have been established.

  3. Configure PWs.

    # Create a VSI on the UPE and specify SPE1 and SPE2 as the VSI peers.

    <UPE> system-view

    # Enable MPLS L2VPN.

    [~UPE] mpls l2vpn
[*UPE-l2vpn] quit
[*UPE] commit

    # Create a VSI on the UPE and configure the LDP signaling type and VSI ID.

    [~UPE] vsi vsi1 static
[*UPE-vsi-vsi1] pwsignal ldp
[*UPE-vsi-vsi1-ldp] vsi-id 1

    # Specify VSI peers so that two PWs can be established between the UPE and SPEs.

    [~UPE-vsi-vsi1-ldp] peer 2.2.2.2
[*UPE-vsi-vsi1-ldp] peer 3.3.3.3
[*UPE-vsi-vsi1-ldp] quit
[*UPE-vsi-vsi1] quit
[*UPE] commit

    You do not need to specify the secondary parameter for the secondary PW, because the PW protection group determines the primary/secondary status of PWs based on PW priorities.

    # Create a VSI on each SPE and specify the UPE and NPEs as VSI peers. The following example uses SPE1. The configuration of SPE2 is similar to the configuration of SPE1. For configuration details, see Configuration Files in this section.

    <SPE1> system-view

[*SPE1] commit

    # Create a VSI on each NPE and specify the SPEs as VSI peers. The following example uses NPE1. The configuration of NPE2 is similar to the configuration of NPE1. For configuration details, see Configuration Files in this section.

    <NPE1> system-view
[~NPE1] mpls l2vpn
[*NPE1-l2vpn] quit

[*NPE1-vsi-vsi1-ldp] quit
[*NPE1-vsi-vsi1] quit
[*NPE1] commit

  4. Add the PWs between the UPE and SPEs to a PW protection group.

    # Configure a PW protection group on the UPE and configure the PW redundancy mode as master/slave. Add the PWs to the PW protection group and specify the priorities of the PWs. Set the revertive switching delay to 60s.

    [~UPE] vsi vsi1 static
[*UPE-vsi-vsi1] pwsignal ldp
[*UPE-vsi-vsi1-ldp] protect-group vsi1
[*UPE-vsi-vsi1-ldp-protect-group-vsi1] protect-mode pw-redundancy master
[*UPE-vsi-vsi1-ldp-protect-group-vsi1] peer 2.2.2.2 preference 1
[*UPE-vsi-vsi1-ldp-protect-group-vsi1] peer 3.3.3.3 preference 2
[*UPE-vsi-vsi1-ldp-protect-group-vsi1] reroute delay 60
[*UPE-vsi-vsi1-ldp-protect-group-vsi1] quit
[*UPE-vsi-vsi1-ldp] quit
[*UPE-vsi-vsi1] quit
[*UPE] commit

    Before adding PWs to a PW protection group, ensure that the PW protection group already exists and its PW redundancy mode is specified. The revertive switching policy can be configured for only PW protection groups with the master/slave PW redundancy mode.

  5. Configure CE2 to interconnect with the NPEs.

    # Configure an E-Trunk between the NPEs.

    [~NPE1] lacp e-trunk system-id 0000-0000-0001
[*NPE1] lacp e-trunk priority 1
[*NPE1] e-trunk 1

    # Configure the local and peer IP addresses of the E-Trunk.

    [*NPE1-e-trunk-1] peer-address 5.5.5.5 source-address 4.4.4.4
[*NPE1-e-trunk-1] quit
[*NPE1] commit

    NPE1 uses the default E-Trunk priority of 100 and the default revertive switching delay of 120s.

    # Add an Eth-Trunk to the E-Trunk.

    [~NPE1] interface eth-trunk 10

  8. Verify the configuration.

    After the configuration is complete, run the following commands to check the configuration.

    1. Ping the VLANIF interface address of CE2 from CE1.

      # Configure the IP address of CE2.

      [~CE2] interface vlanif 10
[*CE2-Vlanif10] ip address 10.1.1.2 255.255.255.0
[*CE2-Vlanif10] quit
[*CE2] commit

      # Perform the ping operation.

    round-trip min/avg/max = 140/178/220 ms

    2. Run the display vsi name protect-group command on the UPE to check PW protection group information. The command output shows that the forwarding state is Active for the primary PW and Inactive for the secondary PW.

      [~UPE] display vsi name vsi1 protect-group vsi1

Protect-group: vsi1
-------------------------------------------------------------------------------
PeerIp:VcId                Pref   Active

3.3.3.3:1                  2      Inactive

    3. Run the display vsi name vsi1 verbose command on the UPE to check information about the VSI and corresponding PWs. The command output shows that VSI State is up, and PW State is up for the primary PW and backup for the secondary PW.

    4. Simulate that the primary PW between the UPE and SPE1 fails. Then service traffic is switched to the secondary PW between the UPE and SPE2.

      Run the display vpls forwarding-info vsi command on the UPE. The command output shows that PW State is up for the secondary PW and backup for the primary PW.

      [~UPE] display vpls forwarding-info vsi vsi1

    5. Simulate that the primary PW between the UPE and SPE1 recovers. Then service traffic is switched back to the primary PW after the specified revertive switching delay expires.

      Run the display vpls forwarding-info vsi command on the UPE. The command output shows that PW State is up for the primary PW and backup for the secondary PW.

      [~UPE] display vpls forwarding-info vsi vsi1
