EIGRP for IPv4 need to match the subnet mask ,K value , AS number, MTU between routers for forming neighbor relationship .
however I saw the question like follwing
Q.How will EIGRPv6 react if there is an IPv6 subnet mask mismatch between the Global Unicast addresses on a poin-to-point link ?
the answer is that EIGRPv6 will form a neighbor relationship .
so I wanna know the neighboring about EIGRPv6 .
Neighboring relationship on EIGRPv6 routers , What factor do i need to match ?

Hi,
IPv6 IGPs form neighborships with the link-local address so they don't care about the global unicast address mismatch.
Apart from that AS, K values and authentication must match to form a neighborship like in IPv4.

Hi,
just to add something:
2. not anymore on latest IOS.
3. yes if you have no IPv4 address on the device then you'll have to specify a router-id
