Alexandre,
The summary command applies to routes as they being redistributed into OSPF
so therefore that command should be on the vienna router. To summarize on
the madrid router(assuming you didn't use the summary command on vienna
already) use the OSPF range command on the madrid router.
viena
router ospf 10
area 1 nssa
area 4 virtual-link 10.10.6.6
redistribute rip metric 1200 metric-type 1 subnets tag 8 route-map
summary-address 16.0.0.0 255.0.0.0
OR
madrid
router ospf 10
area 1 nssa no-redistribution default-information-originate
no-summary
area 0 range 16.0.0.0 255.0.0.0
redistribute eigrp 25 metric 1100 subnets
network 10.10.5.0 0.0.0.255 area 1
network 10.10.10.0 0.0.0.255 area 1
network 10.10.20.0 0.0.0.255 area 0
neighbor 10.10.10.3

Keith
