ASA redistribute EIGRP External (D EX) into OSPF

[esa_fresa]

Running ASA 9.5(3)9. I'm trying to redistribute a D EX route, 10.1.1.0, into OSPF. It's not sending this route to OSPF neighbors. Anyone know why?

access-list 1-to-2-acl standard permit 10.1.1.0 255.255.255.0

route-map 1-to-2 permit 10
 match ip address 1-to-2-acl
 match route-type external type-1 external type-2 internal local nssa-external type-1 nssa-external type-2

router ospf 1
network 192.168.1.0 255.255.255.0 area 0
area 0
log-adj-changes
redistribute eigrp 1 metric 2 metric-type 1 subnets route-map 1-to-2

#sh route
D EX     10.1.1.0 255.255.255.0

Hi Esa,

It's been a while since I've used the route-type keyword, but I think what's going on is since you're specifying a type-1 or type-2, you're actually matching on OSPF external routes which is not what you're intending.

To match on EIGRP external, try using "match route-type external" by itself.  Or just eliminate the route-type.

Also it's preferred to use prefix-lists over ACLs (if available) when dealing with routes.  See below for an example:

prefix-list PL-EIGRP-TO-OSPF permit 10.1.1.0/24 

route-map RM-EIGRP-TO-OSPF permit 10
 match ip address prefix-list PL-EIGRP-TO-OSPF
 match route-type external  (Optionally remove altogether)

router ospf 1
 redistribute eigrp 1 metric 2 metric-type 1 subnets route-map RM-EIGRP-TO-OSPF
