Hi Routing & Switching Community,
As we can notice in our backbone networks today, service providers mostly go with ISIS than OSPF for reasons that have been well explained in previous posts which I will provide below :

Have you ever thought the easy migration to IPv6 from IPv4 using ISIS in the backbone compared to OSPF can also be one of the reasons service providers prefer IS-IS to OSPF ?
Kindly share your thoughts.
