Hierarchy Level


(Optional) Statically map a hostname to one or more IP addresses and aliases, and configure an International Organization for Standardization (ISO) system identifier (system ID).


If you do not statically map the hostname, the mapping is generated dynamically, based on the system configuration. For instance, if you omit the static-host-mapping hostname sysid statement, the IS-IS system ID is dynamically generated from the host portion of the ISO address configured on the loopback interface (lo0) and is mapped to the host-name statement configured at the [edit system] hierarchy level.


alias alias

Alias for the hostname.


Fully qualified hostname.

inet address

IP address. You can specify one or more IP addresses for the host.

sysid system-identifier

ISO system identifier (system ID). This is the 6-byte portion of the Intermediate System-to-Intermediate System (IS-IS) network service access point (NSAP). We recommend that you use the host’s IP address represented in binary-coded decimal (BCD) format. For example, the IP address is 2081.9716.9018 in BCD.
