@Satya97 I have been using IPv6 since last year irregularly. Irregularly because the ONT for some reason stops responding to IPv6 responses and the LAN gateway goes blank. After getting an RPi4 and bridging, I have been using IPv6 almost flawlessly but since the past few days there is a weird issue like IPv6 stops working either on my side or BSNL side.
For anyone that wants to configure IPv6 on their device FTTH Facilitation Center.
