Hi
TTL 2 is when we do broadcast as well as multicast by V1(I tested) and
V2( not tested yet) respectively, and when we use neighbor statements it
goes with the TTL of 1 (Tested) ehich must be TTL of 2 or more for spoke
to spoke advertisement.
But the following blog says when neighbor statements are there, It goes
with the TTL of 255.

As you say, the TTL is 2 whether unicast, broadcast or multicast. I
have never seen the purpose documented. One benefit: it permits
spoke-to-spoke route advertisement using neighbor statements. The same
is true with EIGRP.
