Omar,

I have used route maps during redistribution to do accomplish this task. I
find it simpler to reference the interfaces that I want to redistribute
since it does not require an access list.
i.e
!
interface Loopback0
 ip address 152.1.11.1 255.255.255.240
 no ip directed-broadcast
!
router ospf 1
 redistribute connected subnets route-map Loop0
!
route-map Loop0 permit 10
 match interface Loopback0
!
R1-RouterA#sh ip route conn
     1.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 1.1.1.0/24 is directly connected, Loopback99
     152.1.0.0/16 is variably subnetted, 6 subnets, 3 masks
C 152.1.11.0/28 is directly connected, Loopback0
C 152.1.10.0/24 is directly connected, Ethernet0
C 152.1.1.0/30 is directly connected, Serial0
     168.28.0.0/24 is subnetted, 1 subnets
C 168.28.179.0 is directly connected, Ethernet1

R1-RouterA#sh ip ospf d

       OSPF Router with ID (152.1.11.1) (Process ID 1)

<snip>

                Type-5 AS External Link States

Link ID ADV Router Age Seq# Checksum Tag
152.1.11.0 152.1.11.1 139 0x80000003 0xE56E 0

Folks,
I have a 4 router pod and have ospf up and running.
None of the loopback interfaces have OSPF running on it.
I decided to redistribute the loopback interface of one the backbone
routers
(Router 1) into the ospf network and used the following command....

redistribute connected metric 100 subnet

....on the surface everything seemed fine. The loopback was advertized an
EX
2.
However, when I examined the LS database, I notice that all the connected
links of (Router 1), which already had OSPF running on them, were also
being
advertized by type 5 LSAs.
The remaining routers, perfering the internal routes over external, show
the
(Router 1) connected links as internal but they do have type 5 LSAs in
their
LS database!!!!

It there any way to prevent other connected links being advertized by type
5
LSAs?
I tried route maps but it did not help.
Any suggestions?

Omar.
