DHCPV6 message flow is not as per expectation in case of hyper-v pxe boot over ipv6

Hi Team,
I have hyper-v where I have configured new VM (Gen2) and manage to boot it over ipv6 for Pxe. The firmware of hyper-v currently doesn’t support HTTPClient and hence legacy PXEClient only for tftp transfer. I have set up the system and capture the wireshark. My DHCPv6 message flow is not as per the expectations. I am not receiving Information-Request DHCPv6 message back.
Current scope is just to understand DHCPv6 message flow along with tftp protocol message sequencing only.
Your early reply would be appreciated.
