Example for Configuring a Hybrid SEP+RRPP Ring Network

Networking Requirements

Generally, redundant links are used to connect an Ethernet switching network to an upper-layer network to provide link backup and enhance network reliability. The use of redundant links, however, may produce loops, causing broadcast storms and rendering the MAC address table unstable. As a result, communication quality deteriorates, and services may even be interrupted. SEP can be deployed on the ring network to eliminate loops and restore communication if a link fault occurs.

In this example, you can configure SEP at the access layer to implement redundancy protection switching and configure the topology change notification function on an edge device in a SEP segment. This enables an upper-layer network to detect topology changes in a lower-layer network in time.

Figure 1 Hybrid rings running SEP and RRPP

In Figure 1, multiple Layer 2 switching devices at the access layer and aggregation layer form a ring network to access the core layer. RRPP has been configured at the aggregation layer to eliminate loops. In this case, SEP needs to run at the access layer to implement the following functions:

  • Eliminates loops when there is no faulty link on the ring network.
  • Rapidly restores communication between nodes when a link fault occurs on the ring network.

  • Provides the topology change notification function on an edge device in a SEP segment. This function enables an upper-layer network to detect topology changes in a lower-layer network in time.

    After receiving a message indicating the topology change in a lower-layer network, a device on an upper-layer network sends TC packets to instruct other devices to delete original MAC addresses and learn new MAC addresses after the topology of the lower-layer network changes. This ensures uninterrupted traffic forwarding.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure basic SEP functions.

    1. Configure SEP segment 1 on PE1, PE2, and LSW1 to LSW3 and configure VLAN 10 as the control VLAN of SEP segment 1.

    2. Add PE1, PE2, and LSW1 to LSW3 to SEP segment 1, and configure interface roles on edge devices (PE1 and PE2) of the SEP segment.

    3. Set an interface blocking mode on the device where a primary edge interface is located to specify an interface to block.

    4. Configure the preemption mode to ensure that the specified interface is blocked when a fault is rectified.

    5. Configure the topology change notification function so that the topology change in the local SEP segment can be notified to the upper-layer network where RRPP is enabled.

  2. Configure basic RRPP functions.

    1. Add PE1 to PE4 to RRPP domain 1, create control VLAN 5 on PE1 to PE4, and configure a protected VLAN.

    2. Configure PE1 as the master node and PE2 to PE4 as transit nodes on the major ring, and configure the primary and secondary interfaces of the major ring.

    3. Create a VLAN on PE1 to PE4, and add the interfaces on the RRPP ring network to the VLAN.

  3. Configure the Layer 2 forwarding function on the CE, LSW1 to LSW3, and PE1 to PE4.

Procedure

  1. Configure basic SEP functions.

    1. Configure SEP segment 1 on PE1, PE2, and LSW1 to LSW3 and configure VLAN 10 as the control VLAN of SEP segment 1.

    2. Add PE1, PE2, and LSW1 to LSW3 to SEP segment 1 and configure interface roles.

      By default, STP is enabled on an interface. Before adding an interface to a SEP segment, disable STP on the interface.

      [PE2-GigabitEthernet0/0/1] sep segment 1 edge secondary
      [PE2-GigabitEthernet0/0/1] quit

      After completing the preceding configurations, run the display sep topology command on PE1 to view the topology of the SEP segment. The command output shows that the blocked interface is one of the two interfaces that complete neighbor negotiations last.

    3. Set an interface blocking mode.

      # In SEP segment 1, block the interface in the middle of the SEP segment on PE1 where the primary edge interface resides.

      [PE1] sep segment 1
      [PE1-sep-segment1] block port middle

    4. Set the preemption mode.

      # In SEP segment 1, set manual preemption on PE1 where the primary edge interface resides.

      [PE1-sep-segment1] preempt manual

    5. Configure the topology change notification function.

      # Configure devices in SEP segment 1 to notify topology changes to the RRPP ring network.

      # Configure PE1.

      [PE1-sep-segment1] tc-notify rrpp
      [PE1-sep-segment1] quit

      # Configure PE2.

      [PE2] sep segment 1
      [PE2-sep-segment1] tc-notify rrpp
      [PE2-sep-segment1] quit

    After the preceding configurations are successful, perform the following operations to verify the configurations. PE1 is used as an example.

    • Run the display sep topology command on PE1 to view the topology of the SEP segment.

      The command output shows that the status of GE 0/0/2 on LSW3 is discarding and the status of the other interfaces is forwarding.

    • Run the display sep interface verbose command on PE1 to view detailed information about the interfaces added to the SEP segment.

  2. Configure basic RRPP functions.

    1. Add PE1 to PE4 to RRPP domain 1, create control VLAN 5 on PE1 to PE4, and configure a protected VLAN.

      # Configure PE1.

      [PE1] stp region-configuration

  3. Configure the Layer 2 forwarding function on the CE, LSW1 to LSW3, and PE1 to PE4.

    For the configuration details, see the configuration files.

  4. Verify the configuration.

    After the previous configurations, run the following commands to verify the configuration when the network is stable. LSW1 is used as an example.

    • Run the shutdown command on GE0/0/1 of LSW2 to simulate an interface fault, and then run the display sep interface command on LSW3 to check whether the status of GE0/0/2 changes from blocked to forwarding.
