we resolve tftp option 150 via a DNS lookup<br></font><br></div><div><div></div><div class="Wj3C7c">
<div></div>Have anyone tried DNS server instead of Array to achieve
redundancy?<br><br>Let's say we've 2 x TFTP server for redundancy
purpose.<br>TFTP1 - <a href="http://1.1.1.1" target="_blank">1.1.1.1</a><br>TFTP2- <a href="http://1.1.1.2" target="_blank">1.1.1.2</a><br><br>normally TFTP redundancy is achieved by
creating Array in DHCP. Put both TFTP server ip address in the DHCP.<br>array:
<a href="http://10.1.1.1" target="_blank">10.1.1.1</a> <a href="http://10.1.1.2" target="_blank">10.1.1.2</a><br><br>Instead of putting those IP address
in the array in DHCP config can I put one DNS like name?<br><br>Array:
tftp1tftp2 or <a href="http://tftp.cisco.com" target="_blank">tftp.cisco.com</a><br>In DNS - <a href="http://tftp.cisco.com" target="_blank">tftp.cisco.com</a> has 2 hosts associated to it
e.g. <a href="http://10.1.1.1" target="_blank">10.1.1.1</a> and 10.1.1.2-- <br><br>The DHCP RFC
tells that ICMP is the one which finds out TFTPS erver's subnet but no mention
about DNS address for option 150.<br><br><br>Smile, you'll save someone else's
