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.
