+ * All topologies have the following properties:
+ * - The System-ID is 0000.0000.000X, where X is the node number (in hex);
+ * - The Router-ID is 10.0.255.X, where X is the node number;
+ * - The default link metric is 10;
+ * - When SR is enabled, Adj-SIDs and Prefix-SIDs are generated automatically;
+ * - When SR is enabled, the default SRGB is [16000-23999] (can be overridden).
