summary always creates a route to null0. If you did the configuration different than the solution it doesn't matter. All that matters is results.

I dont know how to continue my troubleshooting. Whats next step? This what I have found: 1) ASA1 config looks ok. Redistributing ospf routes, but only 6.6.2.0 and default: router eigrp 89 no auto-summary network 10.1.1.0 255.255.255.0 network 10.17.17.0 255.255.255.0 redistribute ospf 1 metric 1 1 1 1 1 route-map O2E route-map O2E permit 10 match ip address O2E access-list O2E standard permit host 0.0.0.0 access-list O2E standard permit 6.6.2.0 255.255.255.255 2) ASA1 ospf database contains a 0.0.0.0 Type-5 from 192.1.49.31 3) BUT! ASA1 routing table contains this default route: D* 0.0.0.0 0.0.0.0 is a summary, 0:53:07, Null0 4) R8 contains the 6.6.2.0-route which proves that redistribution works. But there is no default route! R8#sh ip route | beg resort Gateway of last resort is not set 6.0.0.0/8 is variably subnetted, 2 subnets, 2 masks D EX 6.6.2.0/24 [170/2560002816] via 10.1.1.1, 00:46:06, FastEthernet0/1 C 6.6.99.8/32 is directly connected, Loopback0 10.0.0.0/24 is subnetted, 2 subnets D 10.17.17.0 [90/28416] via 10.1.1.1, 00:53:36, FastEthernet0/1 C 10.1.1.0 is directly connected, FastEthernet0/1 5) R9 (on DMZ) gets its summary default-route as expected. R9#sh ip route | beg resort Gateway of last resort is 10.17.17.10 to network 0.0.0.0 10.0.0.0/24 is subnetted, 1 subnets C 10.17.17.0 is directly connected, FastEthernet0/1 D* 0.0.0.0/0 [90/28416] via 10.17.17.10, 00:44:25, FastEthernet0/1 That null0-route in ASA1 confuses me. Where does it come from? Can someone point me into the right direction, not primary to find the solution, but more to teach me how to think. what is next step of logic in troubleshooting a situation like this? Thanks!
