SPBM NSR configuration example

As shown in Figure 15, deploy an SPBM network to meet the following requirements:

• Use I-SID 1000 to extend VLAN 100 across customer sites 1 and 2.

• Use tandem replication for multicast in the SPBM network.

• Assign B-VLAN 10 to I-SID 1000. Map B-VLAN 10 to ECT algorithm 3.

• Enable NSR for SPBM on the BCB.

1. Configure the MST parameters and SPBM feature on BEB 1:

   # Configure MST region parameters. Make sure B-VLAN 10 is mapped to MSTI 4092.

   <BEB1> system-view
   [BEB1] vlan 10
   [BEB1-vlan10] quit
   [BEB1] stp region-configuration
   [BEB1-mst-region] instance 4092 vlan 10
   [BEB1-mst-region] region-name spbm
   [BEB1-mst-region] active region-configuration
   [BEB1-mst-region] quit
   

   # Enable SPBM both globally and on the provider network port Ten-GigabitEthernet 1/0/1. Assign the provider network port to B-VLAN 10.

   [BEB1] spbm
   [BEB1-spbm] quit
   [BEB1] interface ten-gigabitethernet 1/0/1
   [BEB1-Ten-GigabitEthernet1/0/1] spbm enable
   [BEB1-Ten-GigabitEthernet1/0/1] port link-type trunk
   [BEB1-Ten-GigabitEthernet1/0/1] port trunk permit vlan 10
   [BEB1-Ten-GigabitEthernet1/0/1] quit
   

   # Map B-VLAN 10 to ECT algorithm 3.

   [BEB1] spbm
   [BEB1-spbm] ect 3 b-vlan 10
   [BEB1-spbm] quit
   

2. Configure the MST parameters and SPBM feature on BEB 2 and the BCB in the same way you configure BEB 1. (Details not shown.)

3. Configure the customer-side settings on BEB 1:

   # Enable L2VPN.

   [BEB1] l2vpn enable
   

   # Create an SPB VSI (I-SID 1000).

   [BEB1] vsi test
   [BEB1-vsi-test] spb i-sid 1000
   

   # Assign B-VLAN 10 to the SPB VSI.

   [BEB1-vsi-test-1000] b-vlan 10
   

   # Enable tandem multicast replication for the SPB VSI.

   [BEB1-vsi-test-1000] multicast replicate-mode tandem
   [BEB1-vsi-test-1000] quit
   [BEB1-vsi-test] quit
   

   # Assign customer network port Ten-GigabitEthernet 1/0/2 to VLAN 100.

   [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 100
   

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

   [BEB1-Ten-GigabitEthernet1/0/2] service-instance 1
   [BEB1-Ten-GigabitEthernet1/0/2-srv1] encapsulation s-vid 100
   [BEB1-Ten-GigabitEthernet1/0/2-srv1] xconnect vsi test
   [BEB1-Ten-GigabitEthernet1/0/2-srv1] quit
   [BEB1] quit
   

4. Configure the customer-side settings on BEB 2 in the same way you configure BEB 1. (Details not shown.)

5. Enable NSR for SPBM on the BCB.

   <BCB> system-view
   [BCB] spbm
   [BCB-spbm] non-stop-routing
   [BCB-spbm] quit
   

1. Trigger an active/standby switchover on the BCB. (Details not shown.)

2. Verify that the BEBs are unaware of the ongoing active/standby switchover:

   # Verify that the BEB has adjacency with the BCB. This example uses BEB 1.

   <BEB1> display spbm peer
                              Peer information for SPBM
