Hi Nigel,
here are the configs of the router:
R1 (NSSA ABR):
router ospf 1
router-id 100.100.100.100
area 1 nssa default-information-originate
network 11.11.11.11 0.0.0.0 area 0
network 192.168.0.1 0.0.0.0 area 1
R2 (NSSA ASBR):
router ospf 1
router-id 1.1.1.1
area 1 nssa
redistribute rip subnets route-map RIP-TO-OSPF
network 192.168.0.2 0.0.0.0 area 1
!
router rip
redistribute ospf 1 route-map OSPF-TO-RIP
network 10.0.0.0
ip prefix-list OSPF-TO-RIP seq 10 permit 11.11.11.0/24 le 32
ip prefix-list OSPF-TO-RIP seq 20 permit 192.168.0.0/24 le 32
!
ip prefix-list RIP-TO-OSPF seq 10 permit 10.1.0.0/16 le 32
ip prefix-list RIP-TO-OSPF seq 20 permit 200.200.200.0/24 le 32
!
route-map OSPF-TO-RIP permit 10
match ip address prefix-list OSPF-TO-RIP
set metric 10
!
route-map RIP-TO-OSPF permit 10
match ip address prefix-list RIP-TO-OSPF
set metric 100
set metric-type type-2
R3 (RIP only):
router rip
network 10.0.0.0
I also tried the command you told me, but it doesn't also work.
The IOS version which I use on the boxes is 12.0-7T. Maybe a bug ?
What di you think ?
