[Xorp-users] Problem with export policy OSPF

[Jens Dackenberg]

Hi!

I have an issue regarding the route export policy for OSPF. What I have in
my setup is 4 routers that are connected as following:

[ R1 ]  ------BGP----- [R2] ---- [HOST]
   |
   |
 OSPF
   |
   |
[ R3 ]
   |
   |
 OSPF
   |
   |
[ R4 ]

R1 is in ospf area 0, redistributes between BGP and OSPF  (loopback address
1.1.0.1)
R2 is running BGP and redistributes "connected" to BGP  (loopback address
1.1.10.1)
R4 is in ospf area 1   (loopback address 1.1.3.3)
R3 is ABR       (loopback address 1.1.3.1)

My problem is that the loopback address of R1 is not visible at R4 when
enabling BGP-TO-OSPF redistribution in R1.
Is there somebody that can help me sort this out? :-)


My configurations are as following:
