Configuring a Router Hostname and IP Domain Name
This task configures a router hostname and IP domain name.
You must configure the hostname and IP domain name of the router if they have not already been
configured. The hostname and IP domain name are required because the router assigns a fully qualified
domain name (FQDN) to the keys and certificates used by IPSec, and the FQDN is based on the
hostname and IP domain name you assign to the router. For example, a certificate named
router20.example.com is based on a router hostname of router20 and a router IP domain name of
example.com.
