Title: Area 0 interface in OSPF db as Type 5 LSA??
Unless I'm reading this wrong, distribute lists *out* can be used on
an ASBR:
http://www.cisco.com/warp/public/104/9.html#Q9
In my situation, I'm trying to filter an external LSA from entering
into OSPF on the ASBR.
Anyway, as suggested by Roy, I used a route-map while
redistributing EIGRP into OSPF, and that did the trick.
Here's the config:
router ospf 1
summary-address 170.10.26.0 255.255.255.0
summary-address 170.10.1.0 255.255.255.0
redistribute eigrp 1 subnets route-map redis
network 170.10.1.0 0.0.0.255 area 0
network 170.10.2.0 0.0.0.255 area 0
default-metric 64
distribute-list 3 in
!
access-list 1 permit 170.10.2.0 0.0.0.255 <deny ospf demand circuit>
access-list 1 permit 170.10.1.0 0.0.0.255 <deny serial interface>
route-map redis deny 10
match ip address 1
!
route-map redis permit 20
Thank you all for your input.
Cheers,
Aaron

Distribute lists out don't work in OSPF....only distribute lists in
work on the Router they are configured on. However they will only stop
the route from entering the routing table, the LSA will still appear
and be forwarded............
The Type 5 is there because you have the same interface under the the
EIGRP process which is being redistributed and will appear as a type
5......

After redistributing OSPF/EIGRP, my serial interface (OSPF Area 0)
shows up as a Type 5 LSA.
What am I missing?
Distribute lists into OSPF don't seem to work.
