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 interfaces will not. Is this correct? I've been looking through some of
my books and on CCO and from what I gather RIP broadcasts a RIP Request
Message on each RIP-enabled interface and receives a RIP Response message
from a neighboring RIP router that includes that routers routing table. Are
the RIP-enabled interfaces those interfaces in the same major network as the
network command? Would a router running RIP on the far side of a connection
on S1 send a request if it's network was specified in that routers RIP
process causing the local router to send an update out the S1 interface? If
anyone knows or can point me to the appropriate place for the information
I'd appreciate it.
