[OSL | CCIE_RS] RIP v1 - v2 on one router

[Roger RPF]

Hi group,

Question regarding RIPv1 and RIPv2. Following setup

--<R1 RIPv2>---<RIPv2 R2 RIPv1>---<RIPv1 R3>--

If I have to configure RIPv2 between R1 and R2 but RIPv1 between R2 and R3.
I do the following setup on R2:

router rip
version 2
no auto-summary
network <towards R1>
network <towards R3>

interface towards R3
ip rip send version 1
ip rip receive version 1
<rest of the config>

Is there a good reason why I should configure on the interface towards R1,
on my RIPv2 connection, ip rip send version 2?
I don’t see a reason, because I’ve already configured version 2 under the
main process but maybe I’m missing something.

Can anyone give me the “absolution” in this?? **smile**

regards

Roger
