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
InsideHost#

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?

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

O    172.16.0.0/16 [110/20] via 192.168.1.2, 00:00:55, FastEthernet0/0
O    10.0.0.0/8 [110/20] via 192.168.1.2, 00:01:11, FastEthernet0/0
C    192.168.1.0/24 is directly connected, FastEthernet0/0

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