RIP updates

I had a set of 4 routers arranged in a ring, each router linked by serial connections with 2 others. This was set in packet tracer. I also added a couple of switches etc.
Each individual link was fine and I implemented RIP2 on all 4 routers. The last of the 4 routers never updated its routing tables though and never got a single network in its table from RIP in spite of being directly connected to two other routers that were verifiably sending out RIP updates on the interfaces facing the 4th router.
Another oddity was that the debug on the first router was showing one network 16 hops away.
PS what is the unit that the time between rip updates is expressed in?

What is the unit? Well RIP updates every 30 seconds full routing table, is that what you mean? -

Router 1
s0/0 10.0.0.1/8
s0/1 40.0.0.2/8
Fa1/0 11.0.0.1/8
Router 2
s0/0 10.0.0.2/8
s0/1 20.0.0.1/8
Router 3
s0/0 20.0.0.2/8
s0/1 30.0.0.1/8
Fa1/0 12.0.0.1/8
Router 4
s0/0 30.0.0.2/8
s0/1 40.0.0.1/8
router rip
version 2
network - all networks added to all routers
All individual links up up and destinations pingable on routers 1-3.
Router 4 doesn't learn but can function using static routes.Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win.

hostname(config-router)#timers basic ?
<0-4294967295> Interval between updates

Look at the output of 'show ip protocols', you should find timer info in the output. Now change the timers using the 'timers basic' command then reissue the show command.

Cheers Mike, incidently i'm going to chalk up the rip oddities to packet tracer as when I put in a new router and set it up as before it converged immediately.Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win.
