The loopback interfaces on R4 with the IP addresses of 10.4.4.4/32, 10.4.4.5/32, and 10.4.4.6/32 are not appearing in the routing table of R5.
Why are the interfaces missing?

Neighbors must be in the same subnet
K values
AS numbers
Authentication method and key strings
Here, we see that R4 is configured for EIGRP AS 2, when it should be AS 1.
