Hi all ......
I have configure a small scenario of three routers as the following :
(192.168.2.0) (192.168.3.0)
R1 (s1 = .2)
(.1 = s0 ) R2 ( s1 =.1)
(.2 = s0) R3
R1 : 2507
R2 : 2501
R3 : 2507
configure ripv1 on all of them
now i did the following :
R3#debug ip rip
R3#clear ip route *
RIP: sending general request on Serial0 to 0.0.0.0
RIP: sending general request on Serial0 to 224.0.0.9
RIP: received v1 update from 192.168.3.1 on Serial0
192.168.2.0 in 1 hops
RIP: sending v1 update to 0.0.0.0 via Serial0 (192.168.3.2) - suppressing null update
when i do it on R2 i got this :
R2#debug ip rip
R2#clear ip route *
RIP: sending general request on Serial0 to 255.255.255.255

Questions :
1.In R3 Why when clearing routing table it request updated from 0.0.0.0 ( what is this address)
2. In R3 & R2 why they request updates from the multicast address while only using ripV1
