[cisco-voip] Can we resolve tftp option 150 via a DNS lookup

[FrogOnDSCP46EF]

Have anyone tried DNS server instead of Array to achieve redundancy?

Let's say we've 2 x TFTP server for redundancy purpose.
TFTP1 - 1.1.1.1
TFTP2- 1.1.1.2

normally TFTP redundancy is achieved by creating Array in DHCP. Put both
TFTP server ip address in the DHCP.
array: 10.1.1.1 10.1.1.2

Instead of putting those IP address in the array in DHCP config can I put
one DNS like name?

Array: tftp1tftp2 or tftp.cisco.com
In DNS - tftp.cisco.com has 2 hosts associated to it e.g. 10.1.1.1 and
10.1.1.2--

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.


Smile, you'll save someone else's day!
