Michael,
EIGRP will not advertise a network that it is not routing
through EIGRP. Advertising networks via EIGRP that you're not routing
through EIGRP defeats EIGRP's loop prevention mechanisms.
Therefore, unless 150.1.30.0 appears as an EIGRP route in the IP
routing table, the feasible distance will be inaccessible, hence you
will not advertise it to any EIGRP neighbors.

Subject: CyscoExpert EIGRP Zero-Successor Problem
I understand that this lab is designed to introduce such problems, what
is brothering me is why this would happen.
Router R2(E) is redistributing ospf routes into eigrp. Router E has a
full eigrp table with tags and successors.
Router R4(C) is a eigrp neighbor to R2(E) via tunnel, the neighbor
relationship over the tunnel seems healthy. Router C has a full eigrp
top table with tags, but the redistributed routes show up as
zero-successors.
Even with redistribution, I don't understand why with a directly
connected eigrp neighbor E, that C would have zero-successors.
I'm sure my answer is in the flowing displays, but I don't see it.
Tried looking up eigrp zero successor troubleshooting on tac, but
couldn't find a link. Doesn't seem to be a common problem.
TIA!
