RE: forming RIPv2 adjacency in unicast?

Also, here is a great doc that explains how NAT inside/outside source
translation works

Hi Salah,

Let's put the next scenario:

            R1 [fa0/0] ---- [Fa0/0] R2

Lo0 R1: 1.1.1.1 /32
Fa0/0 R1: 12.12.12.1/24

Lo0 R2: 2.2.2.2/32
FA0/0 R2: 12.12.12.2/24

On R1:

int fa0/0
 ip nat outside
ip nat outside source static udp 2.2.2.2 520 224.0.0.9 520 ip route 2.2.2.2
255.255.255.255 fa0/0 12.12.12.2

On R2:

int fa0/0
 ip nat outside
ip nat outside source static udp 1.1.1.1 520 224.0.0.9 520 ip route 1.1.1.1
255.255.255.255 fa0/0 12.12.12.1

Try this, it works. I'm sure there is another way to do it, but this one
goes good.

This is one of the most weird things I've seen. You have to use NAT to
translate the multicast address into a unicast address.

how u would do it without neighbor command?

by default RIPv2 to multicast group , the only command will change this
behavior to unicast is neighbor command :-) ,
