2. Create an indirect file that contains a path and the name of the firmware version
(for example indirect-cisco.txt that contains cisco\cisco-version.ros).
3. Copy this indirect file to the TFTP/SCP server’s main directory
DHCP Server
Configure the DHCP server with the following options
• DHCPv4—Option 125 (indirect file name)
• DHCPv6—Options 60 (name of configuration file plus indirect image file
name, separated by a comma)
