Fellows,

The questions says:

4.10. IGP Redistribution
. Mutually redistribute between RIP and OSPF on R3 and R4.
. Routers in the OSPF domain should see two summary routes for the
networks learned from BB3.
. Do not overlap any address space when creating these summaries.
. The summaries should have a cumulative metric throughout the OSPF
domain, while the route to VLAN 43 should always be seen with a metric
of 100 throughout the OSPF domain.

My solution was:

router ospf 1
 summary-address 30.0.0.0 255.252.0.0
 summary-address 31.0.0.0 255.252.0.0
 redistribute rip subnets route-map RIP->OSPF
!
router rip
 redistribute ospf 1 metric 1
 !
ip prefix-list RIP->OSPF seq 5 permit 30.0.0.0/24
ip prefix-list RIP->OSPF seq 10 permit 30.1.0.0/24
ip prefix-list RIP->OSPF seq 15 permit 30.2.0.0/24
ip prefix-list RIP->OSPF seq 20 permit 30.3.0.0/24
ip prefix-list RIP->OSPF seq 25 permit 31.0.0.0/24
ip prefix-list RIP->OSPF seq 30 permit 31.2.0.0/24
ip prefix-list RIP->OSPF seq 35 permit 31.1.0.0/24
ip prefix-list RIP->OSPF seq 40 permit 31.3.0.0/24
!
ip prefix-list VLAN43 seq 5 permit 204.12.1.0/24
!
route-map RIP->OSPF permit 10
 match ip address prefix-list RIP->OSPF
 set metric-type 1
route-map RIP->OSPF permit 20
 match ip address prefix-list VLAN43
 set metric-type type-2
 set metric 100

It did not work. The route to 204.12.1.0/24 was being received as E1 and cumulative metric. The workbook solution inverted the logic:

router ospf 1
 summary-address 30.0.0.0 255.252.0.0
 summary-address 31.0.0.0 255.252.0.0
 redistribute rip subnets route-map RIP->OSPF
!
router rip
 redistribute ospf 1 metric 1
 !
ip prefix-list VLAN43 seq 5 permit 204.12.1.0/24
!
route-map RIP->OSPF permit 10
 match ip address prefix-list VLAN43
 set metric 100
route-map RIP->OSPF permit 20
 set metric-type type-1

So I ask: What4s wrong in my solution? I did not get the point. As far as my knowledge goes it should work as well.

Thanks in advance.
