Cisco ASA OSPF (Static Redistribution)

Hi

Firewalls I'm happy with, but Routing is not really my thing, so bear with me.

Here's the topology, ASA has failover ISP links and that works fine;

topologyThe ASA is set to redistribure Static

router ospf 10
 network 192.168.1.0 255.255.255.0 area 0
 log-adj-changes
 redistribute static
!
route outside 0.0.0.0 0.0.0.0 172.16.1.1 1 track 1
route backup 0.0.0.0 0.0.0.0 10.0.0.1 2

Open in new window


Why does the LAN router never get the default route?

InsideHost#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

C    192.168.1.0/24 is directly connected, FastEthernet0/0

Even if I add the two ISP networks from the ASA Like so............

\!
router ospf 10
 network 10.0.0.0 255.0.0.0 area 0
 network 172.16.0.0 255.255.0.0 area 0
 network 192.168.1.0 255.255.255.0 area 0
 log-adj-changes
 redistribute static

The default route does not get to the LAN router?

       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

In OSPF, you have to add the line "default-information originate" to get OSPF to redistribute the default route.
