SPBM configuration examples
This section provides configuration examples to configure basic SPBM and IS-IS infrastructure.
Examples and network illustrations in this document may illustrate only one of the supported platforms. Unless otherwise noted, the concept illustrated applies to all supported platforms.
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.
IS-IS SPBM global
The following sections show the steps required to configure the global IS-IS SPBM parameters in this example.

IS-IS SPBM Interface Configuration
The following figure shows the IS-IS area information and interfaces in the network.
IS-IS SPBM interface
The following sections show the steps required to configure the IS-IS SPBM interfaces in this example.
SwitchC
