Basic SPBM configuration example
Network requirements
Deploy an SPBM network as shown in Figure 10.
Use I-SID 1000 to extend VLAN 100 across customer sites 1, 2, and 3. Configure I-SID 1000, as shown in Table 5.
Table 5: SPBM service requirements
Item | Requirements |
|---|---|
B-VLAN | VLAN 10 |
ECT algorithm index | 3 |
Multicast replication | Tandem replication |

Configuration procedure
Configure basic SPBM parameters:
# Create VLAN 100 and B-VLAN 10.
<BEB1> system-view [BEB1] vlan 100 [BEB1-vlan100] quit [BEB1] vlan 10 [BEB1-vlan10] quit
# Configure MST region parameters on BEB 1. Make sure B-VLAN 10 is mapped to MSTI 4092.
[BEB1] stp region-configuration [BEB1-mst-region] region-name spbm [BEB1-mst-region] instance 4092 vlan 10 [BEB1-mst-region] active region-configuration [BEB1-mst-region] quit
# Enable SPBM both globally and on the provider network ports on BEB 1, and assign the provider network ports to 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 [BEB1] interface ten-gigabitethernet 1/0/3 [BEB1-Ten-GigabitEthernet1/0/3] spbm enable [BEB1-Ten-GigabitEthernet1/0/3] port link-type trunk [BEB1-Ten-GigabitEthernet1/0/3] port trunk permit vlan 10 [BEB1-Ten-GigabitEthernet1/0/3] quit
# Repeat the previous steps to configure the MST parameters and SPBM feature on all other BEBs and BCBs. (Details not shown.)
![[NOTE: ]](images/note.png)
NOTE:
On BCBs, you must enable SPBM on all the ports in the SPBM network.
Map B-VLAN 10 to ECT algorithm 3:
# Map B-VLAN 10 to ECT algorithm 3 on BEB 1.
[BEB1] spbm [BEB1-spbm] ect 3 b-vlan 10 [BEB1-spbm] quit
# Repeat the previous step to map B-VLAN 10 to ECT algorithm 3 on all other BEBs and BCBs. (Details not shown.)
Configure the Ethernet service instance for VLAN 100 on the customer edge port on BEB 1:
# Enable L2VPN.
[BEB1] l2vpn enable
# Create an SPB VSI (I-SID 1000) for VLAN 100 traffic.
[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 mode for the SPB VSI.
[BEB1-vsi-test-1000] multicast replicate-mode tandem [BEB1-vsi-test-1000] quit [BEB1-vsi-test] quit
# Create Ethernet service instance 1, assign VLAN 100 to this instance, and map the service instance to the SPB VSI.
[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 [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-Ten-GigabitEthernet1/0/2] quit [BEB1] quit
# Repeat the previous step to configure the Ethernet service instance for VLAN 100 on all other BEBs. (Details not shown.)
Verifying the configuration
Use Table 6 to verify that all the SPBM nodes have correctly established ISIS-SPB adjacencies and collected topology data, and that the BEBs have correctly established PWs.
Table 6: B-MACs of SPBM nodes
BEB | B-MAC | BCB | B-MAC |
|---|---|---|---|
BEB 1 | 0011.2200.1101 | BCB 1 | 0011.2200.1401 |
BEB 2 | 0011.2200.1201 | BCB 2 | 0011.2200.1501 |
BEB 3 | 0011.2200.1301 |
Verify the configuration on BEBs (for example, BEB 1):
# Verify that the BEB has ISIS-SPB adjacencies with all its neighbors.
