Hi Raymond, I would anticipate that the routing information Router B is receiving is only IGRP routing info, due to the fact you made S1 not pass any EIGRP routing updates - whether they are static or dynamic with the PASSIVE-INTERFACE command.
>From the config, only IGRP is allowed to distribute routing info out of S1 on Router A. This is correctly advertising only the SUMMARY route for the network at it's class boundry, ie 172.16.0.0.
