By disabling split horizon which happens by default in frame-relay
interfaces for RIP (
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/iprrp_r/ip2_i1g.htm#wp1040887)
it does not mean that this interface will not participate in sending and
receiving updates. It just means that you will be able to announce a route
out the same interface that you received it (which is helpful in hub and
spoke environments).
The no ip directed-broadcast command I dont see how it would be helpful in
this case since it works for forwarding broadcasts received in one interface
to another interface, also RIP version 2 does not use broadcast but the
multicast address 224.0.0.9.
Now the problem here is that a passive interface just means that it will not
be sending updates out, however if the network command encompasses this
interface we will be sending this route out the interfaces that are
participating in sending updates.
My recommendation to just announce the route of the serial 0/0/0 interface
would be to use a distribute list out the serial 0/0/0 interface under the
RIP process. this way you will only be permitting the update to contain the
network of the serial 0/0/0 interface.
Router rip
distribute list 1 out serial0/0/0
access-list 1 permit 7.7.100.0 0.0.0.255
Just my two cents
