I modified one of my simulations for EIGRP Stub. I did it for both IPv4 and IPv6. Flat-1 connects to the real world for TFTP Redirection.
You will see the routers on the right side have 4 types of stubs. iosv12 and iosv14 were removed for this. Each stub router connects to two routers. You can see the stub types in sh ip protocols and sh ip eigrp neighbors detail. Each router has a loopback 172.20.x.x.
I used EIGRP Named protocol. EIGRP Router-ID for IPv4 is 172.22.4.x and EIGRP Router-ID for IPv6 is 172.22.6.x. X is iosv-x. You will notice in the sh ip route and sh ipv6 route some of the loopbacks are missing. Check the actual router and you will see it in the routing table.
