Code 1 to 10 of CLV are defined in ISO 10589 (code 3 and 5 are not shown in the table), and others are
defined in RFC 1195.

Supported IS-IS Features

Multiple instances and processes
IS-IS supports multiple instances and processes. Multiple processes allow a IS-IS process to work in
concert with a group of interfaces. This means that a router can run multiple IS-IS processes, and each
process corresponds to a unique group of interfaces.
For routers supporting VPN, each IS-IS process is associated with a VPN instance. Thus, the VPN
instance is also associated with interfaces corresponding to the process.
