15.3 Getting the configuration with TFTP
Once the Telindus 1031 Router has obtained an IP address, it is reachable over its LAN interface. Now
you can start a TMA or a Telnet session on the Telindus 1031 Router and configure it.
Alternatively the Telindus 1031 Router can retrieve its complete configuration without any user interven-
tion. As long as the previously obtained IP addresses are not stored in non-volatile memory, the Telindus
1031 Router tries to get a complete configuration file from a TFTP server.
The configuration file and TFTP
The Trivial File Transfer Protocol is typically used in combination with BootP to obtain the configuration
of a device from a TFTP server. The configuration file on this TFTP can be in a binary or an ASCII format.
How to build such files is explained in
15.4 - Creating configuration files on page 347 .
Getting the configuration file with TFTP
The Telindus 1031 Router asks for its configuration file as follows:
Phase Description
1 The Telindus 1031 Router sends a DNS request on the interface for which it received an
IP address. This request is a local broadcast message.
If it sent over the WAN link, the peer router should have an IP helper address for the DNS
server.
If no reply is received within 10 seconds, this phase is repeated once more.
2 If a DNS reply is received, it contains the domain name. The Telindus 1031 Router only
uses the hostname part of the domain name:
hostname.domain.toplevel_domain .
