If you cannot use auto-summary or ip summary-address then I would summurize
in the protocol that exists between R1 and R2 whatever that is , then
redistribute the summary on R2 in RIP so that R3 can get it.
Here is your case scenario using OSPF.
===================
Please note that I have changed the name of the routers.
==================
lo0---R2------10.2.4.0/24-----R4--------212.4.6.0/24------R6
OSPF 0 is running between R2 and R4.
RIP is running between R4 and R6
I have NOT put lo0 in the OSPF process.
Here is the configurations:
!r2
int lo 0
ip addr 10.255.255.255.2 255.255.255.255
router ospf 100
router-id 150.1.2.2
!
passive default
no passive fa 0/0
network 10.2.4.0 0.0.0.255 area 0
!
redistribute connected route-map lo0
!
summary-address 10.0.0.0 255.0.0.0
!
route-map lo0 permit 10
match int lo 0
!r4
router rip
version 2
!
passive default
no passive e 0/1
network 212.4.6.0
!
no auto
!
distribute-list 1 out ! this is necessary so that R4 does not send via RIP
its connected interface e0/0
!
access-list 1 permit 10.0.0.0
!
router rip
redistribute ospf 100 metric 1!r4
R4#debug ip rip
R4#
*Mar 1 02:04:14.724: RIP: sending v2 update to 224.0.0.9 via Ethernet0/1
(212.4.6.4)
*Mar 1 02:04:14.724: RIP: build update entries
*Mar 1 02:04:14.724: 10.0.0.0/8 via 0.0.0.0, metric 1, tag 0
r6#
r6#sh ip route rip
R 10.0.0.0/8 [120/1] via 212.4.6.4, 00:00:07, Ethernet0/1 ! only 1 update
is sent which is the summary desired
