Configuration hierarchy
An overview of the configuration hierarchy and the related commands.
vRouter configuration is organized as a hierarchy of configuration statements, with a hierarchical tree of nodes similar to the directory structure on a UNIX file system. Three kinds of statements exist:
- Configuration nodes. These nodes can be either:
- Single nodes (just one instance can be created; for example, the rip protocol node)
- Multinodes (more than one instance can be created; for example, address nodes)
- Attribute statements. These statements set the values or characteristics for parameters within a node.
From a system perspective, a configuration node is different from a simple configuration attribute statement. A configuration attribute statement takes the form attribute value, as in the following example.
protocol-version v2
A configuration node always has an enclosing pair of braces, which may be empty, as in the following example,
service {
https{}
}
or nonempty, as in the following example.
ssh {
allow-root
}
