I am missing something here In your packet capture analysis at 2:26 I don't see an hello from r1 back to R2 with active neighbor of r2 router Id. If R2 recieves hello from r1 with its own router Id, only then it will move to 2way isn it?
Here is the link to download the pcap - drive.google.com/file/d/1sLrOAARUm2l04q7iHHdAS8MnI1EraAoc/view?usp=drive_link As you see the 9th packet is a DBD from R1 to R2, Receiving a DBD packet from a neighbor in the init state can also a cause a transition to 2-way state. Here thats what happened, R2 received a DBD from R1 when R1 moved from 2way to Exstart
Well explained! These details are becoming the norm of today but many great tutors just scratch the surface.
Thank you
