SPBM Configuration Examples
This section provides configuration examples to configure basic SPBM and IS-IS infrastructure.
Examples and network illustrations in this document may not include your specific platform. Unless otherwise noted, the concept illustrated applies to all supported platforms. For information about high-level feature support, see Fabric Engine and VOSS Feature Support Matrix.
Basic SPBM configuration example
The following figure shows a sample greenfield deployment for SPBM.
 
            
Note
For migration purposes, SPBM can coexist with existing SMLT configurations.
Ethernet and MLT configuration
The following sections show the steps required to configure the Ethernet and MLT interfaces in this example.
SwitchC
PORT CONFIGURATION - PHASE 1 interface GigabitEthernet 1/30 encapsulation dot1q exit
SwitchG
PORT CONFIGURATION - PHASE 1 interface GigabitEthernet 1/5 encapsulation dot1q exit MLT CONFIGURATION mlt 1 enable mlt 1 member 1/21-1/22 mlt 1 encapsulation dot1q
SwitchD
MLT CONFIGURATION mlt 1 enable mlt 1 member 1/20,1/30 mlt 1 encapsulation dot1q
IS-IS SPBM global configuration
The following figure shows the IS-IS area information added to the network.

The following sections show the steps required to configure the global IS-IS SPBM parameters in this example.
SwitchC

IS-IS SPBM Interface Configuration
The following figure shows the IS-IS area information and interfaces in the network.
 
The following sections show the steps required to configure the IS-IS SPBM interfaces in this example.
SwitchC
PORT CONFIGURATION - PHASE II interface GigabitEthernet 1/30 isis isis spbm 1 isis enable exit
SwitchG
PORT CONFIGURATION - PHASE II interface GigabitEthernet 1/5 isis isis spbm 1 isis enable exit MLT INTERFACE CONFIGURATION interface mlt 1 isis isis spbm 1 isis enable exit
SwitchD
MLT INTERFACE CONFIGURATION interface mlt 1 isis isis spbm 1 isis enable exit
Verify SPBM Operations
The following sections show the output from verifying the sample IS-IS SPBM configuration.
