Thx for all your help guys I found the same thing out in my test lab at
home.

You guys are correct. I continued to try and find a doc that supported my
understanding only to find that I was wrong.
We setup a lab environment with the following setup.
E1 = 192.168.1.1 /24
S0/0 = 10.1.1.1 /8
Router Rip
Network 10.0.0.0
Debug ip rip
The debug trace shows RIP updates only being sent out the S0/0 port.
Sorry for misleading anyone, but as it was stated earlier, you learn
something new every day!

That's what I thought. I'll try doing a test at home on my
setup and see
what it yields.

If anyone has a router to do debugs on, please check this.
The Cisco
documentation says that it only sends out RIP updates on
the networks (and
thus, interfaces) indicated as part of router rip, which
makes perfect
sense
to me.
from
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/np1_c
/1cprt1/1crip.htm
comes
RIP sends updates to the interfaces in the specified
networks. If an
interface's network is not specified, it will not be
advertised in any RIP
update.
So, I believe James is correct, based on the
documentation.

My understanding is that when you enable RIP, it will
broadcast the
route
table out all interfaces where IP is running. The
network statement is
used
to designate which networks are added to the route
table.
Example:
E1 = 10.1.1.1 /8
E2 = 11.1.1.1 /8
E3 = 192.168.1.1 /24
Router rip
Network 10.0.0.0
Network 11.0.0.0
The route table will contain the 10.0.0.0 /8 and
11.0.0.0 /8 networks
and
NOT the 192.168.1.1 /24 network. However the route
table will be
broadcast
out all 3 Ethernet ports. If you do not want the table
broadcast out a
certain port, then you have to use the passive-interface
command.

Subject: RIP Updates [7:2270]
I'm currently having a discussion with a fellow
employee
who passed the
CCIE Written about a year ago. Has no plans to take the
lab,
but that's
neither here no there. He claims that when RIP is
enabled on
a router it
floods it's updates out all interfaces on the router by
default. I was of
the impression that the updates are only broadcast out
interfaces that have
ip addresses in the same major network as the network
command when
configuring RIP.
For example:
A router with four interfaces (addresses made up)
E0 130.10.12.1
E1 130.10.13.1
S0 130.10.20.1
S1 170.23.15.1
To0 no ip address, but up for bridging.
If I configure RIP as:
router rip
network 130.10.0.0
then E0,E1,and S0 will send Rip updates out those
interfaces, but S1, and
To0
