Matthew,
Is there a reason why you chose NOT to put a static route in RtrB as the
author indicated? I think what he was trying to point out is that if you
specify the static that matches the RIP interface's mask and set the
next hop to RtrB's e0, then there is no need to use the REDISTRIBUTE
static command since RIP also "owns" e0's MAJOR network.
An even better scenario to explain RIPv1's behavior is to mock up this

Exercise 2, Page 739 - OSPF to RIPv1.
The only way I can get this to work is change the mask on RB E1 to /28
(as
in part 1.), although the solution clearly states no need!
N.B. RB E1 is my S1/1
RB E0 is my S1/0
The ints on the left are loopbacks with IP OSPF NETWORK PONT_TO_POINT
RB routing table -
Gateway of last resort is not set
172.16.0.0/16 is variably subnetted, 10 subnets, 3 masks

A Debug IP Rip on RB shows :

03:43:24: RIP: build update entries - suppressing null update
Relevant config on B is :

!
interface Serial1/1

router ospf 1

!
router rip
redistribute ospf 1 metric 2
passive-interface S1/0
network 172.16.0.0
Any ideas?
