I have established communication between tcp client and server via IPv6 , for
that ipv6 ip generated in stm32 board. That is working alright , but the
problem is, IPv6 ip is not there in router's log, ipv4 ip i there. see below
screenshots.

But ipv6 is not in the list.
I don't know if it is lwIP's duty to show up there. Are you even seeing
other devices' IPv6 address there?
When using IPv6, I suppose you do know the difference between dhcp
(IPv4) and SLAAC.
We do not support DHCPv6, yet, so that might be a difference to other
IPv6 devices. However, this is not used as often as SLAAC and certainly
is not required to get a routable address.
Also here is the log of gnetif for lwip communication of stm32.

With the above image you can see clearly that I can communicate via IPv6 ,
but I am not getting ip6_addr[2] which is empty.
What would you expect to get there? [0] is reserved for a link-local
address but all other slots are for autoconfig addresses. One should be
enough ([1] in your case).
What is it exactly that's not working for you? Is this only a question
of "where can I find the address of my device"?
