2.1. IS-IS Configuration 2.1. IS-IS Configuration
The IS-IS configuration is divided into: The IS-IS configuration is divided into two areas:
o Global parameters. * Global parameters
o Per-interface configuration (see Section 2.4). * Per-interface configuration (see Section 2.4)
Additional modules may be created to support additional parameters. Additional modules may be created to support additional parameters.
These additional modules MUST augment the ietf-isis module. These additional modules MUST augment the "ietf-isis" module.
The model includes optional features, for which the corresponding The model includes optional features for which the corresponding
configuration data nodes are also optional. As an example, the configuration data nodes are also optional. As an example, the
ability to control the administrative state of a particular IS-IS ability to control the administrative state of a particular IS-IS
instance is optional. By advertising the feature "admin-control", a instance is optional. By advertising the feature "admin-control", a
device communicates to the client that it supports the ability to device communicates to the client that it supports the ability to
shutdown a particular IS-IS instance. shut down a particular IS-IS instance.
The global configuration contains usual IS-IS parameters, such as, The global configuration contains the usual IS-IS parameters, e.g.,
lsp-mtu, lsp-lifetime, lsp-refresh, default-metric, etc. "lsp-mtu", "lsp-lifetime", "lsp-refresh", "default-metric".

Some specific parameters can be defined on a per-topology basis, both Some specific parameters can be defined on a per-topology basis, at
at the global level and at the interface level: for example, an both the global level and the interface level: for example, an
interface metric can be defined per topology. interface metric can be defined per topology.
Multiple address families (such as, IPv4 or IPv6) can also be enabled Multiple address families (such as IPv4 or IPv6) can also be enabled
within the default topology. This can be achieved using the address- within the default topology. This can be achieved using the

2.3. Per-Level Parameters 2.3. Per-Level Parameters
Some parameters allow a per-level configuration. For such Some parameters allow per-level configuration. For such parameters,

configuration applies to both levels. Corresponds to "level-all", so the configuration applies to both
levels.
o a Level-1 container: Corresponds to level-1 specific parameters. A level-1 container:
Corresponds to parameters specific to level 1.
o a Level-2 container: Corresponds to level-2 specific parameters. A level-2 container:
Corresponds to parameters specific to level 2.
