SPBM with tandem replication configuration example

As shown in Figure 12, deploy an SPBM network to meet the following requirements:

• Use I-SID 3001 to extend VLAN 100 across customer sites 1, 2, and 3.

• Use tandem replication for multicast in the SPBM network.

• Assign B-VLAN 3001 to I-SID 3001.

1. Configure BEB 1:

   # Create VLAN 100 and B-VLAN 3001.

   <BEB1> system-view
   [BEB1] vlan 100
   [BEB1-vlan100] quit
   [BEB1] vlan 3001
   [BEB1-vlan3001] quit
   

   # Configure MST region parameters on BEB 1. Make sure B-VLAN 3001 is mapped to MSTI 4092.

   [BEB1] stp region-configuration
   [BEB1-mst-region] region-name spb
   [BEB1-mst-region] instance 4092 vlan 3001
   [BEB1-mst-region] active region-configuration
   [BEB1-mst-region] quit
   

   # Enable SPBM both globally and on the provider network port on BEB 1. Assign the provider network port to B-VLAN 3001.

   [BEB1] spbm
   [BEB1-spbm] quit
   [BEB1] interface ten-gigabitethernet 1/0/2
   [BEB1-Ten-GigabitEthernet1/0/2] port link-type trunk
   [BEB1-Ten-GigabitEthernet1/0/2] port trunk permit vlan 3001
   [BEB1-Ten-GigabitEthernet1/0/2] spbm enable
   [BEB1-Ten-GigabitEthernet1/0/2] quit
   

   # Enable L2VPN.

   [BEB1] l2vpn enable
   

   # Create an SPB VSI (I-SID 3001).

   [BEB1] vsi test
   [BEB1-vsi-test] spb i-sid 3001
   

   # Assign B-VLAN 3001 to the SPB VSI.

   [BEB1-vsi-test-3001] b-vlan 3001
   

   # Enable tandem multicast replication for the SPB VSI.

   [BEB1-vsi-test-3001] multicast replicate-mode tandem
   [BEB1-vsi-test-3001] quit
   [BEB1-vsi-test] quit
   

   # Assign customer network port Ten-GigabitEthernet 1/0/1 to VLAN 100.

   [BEB1] interface ten-gigabitethernet 1/0/1
   [BEB1-Ten-GigabitEthernet1/0/1] port link-type trunk
   [BEB1-Ten-GigabitEthernet1/0/1] port trunk permit vlan 100
   

   # Configure Ethernet service instance 1 to match VLAN 100, and map the service instance to the SPB VSI.

   [BEB1-Ten-GigabitEthernet1/0/1] service-instance 1
   [BEB1-Ten-GigabitEthernet1/0/1-srv1] encapsulation s-vid 100
   [BEB1-Ten-GigabitEthernet1/0/1-srv1] xconnect vsi test
   [BEB1-Ten-GigabitEthernet1/0/1-srv1] quit
   [BEB1-Ten-GigabitEthernet1/0/1] quit
   

2. Repeat the previous steps to configure the MST parameters and SPBM feature on BEB 2 and BEB 3. (Details not shown.)

3. Configure the BCB:

   # Create B-VLAN 3001.

   <BCB> system-view
   [BCB] vlan 3001
   [BCB-vlan3001] quit
   

   # Configure MST region parameters on the BCB. Make sure B-VLAN 3001 is mapped to MSTI 4092

   [BCB] stp region-configuration
   [BCB-mst-region] region-name spb
   [BCB-mst-region] instance 4092 vlan 3001
   [BCB-mst-region] active region-configuration
   [BCB-mst-region] quit
   

   # Enable SPBM both globally and on the provider network ports on the BCB. Assign the provider network ports to B-VLAN 3001.

   [BCB] spbm
   [BCB-spbm] quit
   [BCB] interface ten-gigabitethernet 1/0/1
   [BCB-Ten-GigabitEthernet1/0/1] port link-type trunk
   [BCB-Ten-GigabitEthernet1/0/1] port trunk permit vlan 3001
   [BCB-Ten-GigabitEthernet1/0/1] spbm enable
   [BCB-Ten-GigabitEthernet1/0/1] quit
   [BCB] interface ten-gigabitethernet 1/0/2
   [BCB-Ten-GigabitEthernet1/0/2] port link-type trunk
   [BCB-Ten-GigabitEthernet1/0/2] port trunk permit vlan 3001
   [BCB-Ten-GigabitEthernet1/0/2] spbm enable
   [BCB-Ten-GigabitEthernet1/0/2] quit
   

Verify the configuration on BEBs (for example, BEB 1).

1. Verify that the BEB has ISIS-SPB adjacency with its neighbor.

   [BEB1] display spbm peer
                              Peer information for SPBM
                              -------------------------
    System ID         Port                        Circuit ID    State    Holdtime

2. Verify that the BEB has established tunnels to other BEBs.

   [BEB1] display l2vpn vsi name test verbose
   VSI Name: test
     VSI Index               : 1
     VSI State               : Up

   The output shows that a multicast tunnel has been established for tandem multicast replication.
