BSNL carried out IPv6 in Bharat Fiber (FTTH) Broadband network; How to configure IPv6 on your FTTH ONT?

BSNL Broadband Network team has implemented dual stack

During those epidemic days, BSNL is aggressively adding Bharat Fiber (FTTH) customers across India. Due to its superior overall performance and assured bandwidth even at peak hours as compared to other Fiber broadband carriers, netizens started selling BSNL FTTH packages. Since the majority of current day sports are now entirely dependent on the internet during this lockdown, reliable internet access is a major issue for everyone.

With the help of TIPs, LCOs, and MSOs, among others, BSNL’s channel partners, has just achieved 1 million subscriber bases in the FTTH category. The PSU has enabled IPv6 in its Bharat Fiber (FTTH) Broadband network due to the fast exponential growth in the number of Fiber Broadband (FTTH) consumers. The deployment of IPv6 is anticipated to improve the surfing experience for BSNL FTTH users.
Before, BSNL gave its FTTH network users public IPv4 addresses. These days, there are an exponentially growing number of FTTH subscribers, thus there is a potential that the IPv4 address space may run out quickly. The BSNL Broadband Network team has made measures to solve the issue of a severe lack of IPv4 addresses.

What is BNG?

A device for terminating subscriber traffic is a BNG (Broadband Network Gateway). In essence, BNG is a router. The user can get several services (Internet, phone, and IPTV) through a single connection since it is in charge of routing inside the service network.

How can I set up my FTTH ONT to use IPv6?

Most websites today are IPv6 compatible, therefore clients that enable IPv6 in their FTTH ONT / ONU (FTTH Modem) may enjoy enhanced browsing. You can modify the WAN settings in your ONT / ONU (FTTH Modem) to activate IPv6 in your BSNL FTTH connection.

You must switch to IPv4 or IPv6 for your WAN profile’s Internet connection. It is currently set up in your ONT as IPv4.

The following describes how to configure IPv6 on Netlink, Syrotech, and Tech Next ONTs: –

Step 1:For the WAN profile built for the Internet, change the IP Protocol Mode to IPv4/IPv6. Network > Internet is the path. Choose “Staleless” IPv6 addresses and turn on DHCP PD (DHCP Prefix Delegation).

Step 2: You might also need to make additional adjustments to the LAN IP Address > IPv6 Configuration, as seen in the photo below, in addition to the modifications mentioned above. Here, you must choose the WAN profile made for the Internet to establish the LAN DNS and LAN IPv6 Prefix. (Details may be seen below).

Step 3: DHCP configuration for IPv6. In this case, you must enable DHCPv6 Mode (see below).

Step 4: Configuring the RA. In your FTTH ONT, you must now allow Router – Advertisement (RA) messages. To do this, open the RA Configuration tab and turn on each of the three options as seen in the image below. Each configured interface of an IPv6 router regularly transmits RA (Router Advertisement) messages. Your router may regulate the routing configuration for choosing the appropriate network interface to connect to its neighboring network elements via RA messages.

I’m done now. Your BSNL FTTH ONT has been successfully setup for IPv6. You may now check the IPv6 Connection Information section of the Status page on your BSNL FTTH ONT to see if it has an IPv6 address. As indicated in the image below, IPv6 addresses, IPv6 Prefixes, and IPv6 DNS are also allocated.

Your router could also provide IPv6 to your computer or laptop. Simply choose the IPv6 option for your Network Adapter if you are having trouble receiving an IPv6 address for your computer. (As shown in the illustration below).

Now, you can observe from the Connection Details (as seen below) that IPv6 addresses and IPv6 DNS are allocated separately from IPv4 addresses.

Check IPv6 now by going to https://test-ipv6.com/ (As shown in the illustration below). You can also find your IP address by performing a Google search for “What is my ip.”

You may also determine if you have an IPv6 address by going to the IPv6-only website http://42.be/. If IPv6 has been setup correctly, you might see the screen below.

Below is a fast reference for some of the most common FTTH ONTs’ IPv6 Configuration Guides.

  • Setting BSNL IPv6 Genexus Platinum 4410
  • Setting BSNL IPv6 on a Huawei EG8141A5
  • Setting BSNL IPv6 on the TP Link Archer XR500v
  • Setting BSNL IPv6 in Alphion 1143 Black
  • NGN ONT Setting for BSNL IPv6
  • Setting BSNL IPv6 in Netlink / Syrotech

You are still not receiving an IPv6 address on your BSNL FTTH (Bharat Fiber) connection.

Only their Juniper BNGs have IPv6 deployed at this time by BSNL. Customers who are currently linked exclusively through Juniper BNGs may receive IPv6 addresses. You may still receive an IPv4 address until BSNL upgrades your BNG server to IPv6 if you are not receiving IPv6, this indicates that you are not connected to Juniper BNG.
