Hi,
my question:
i have a router, which is connected to two different areas -100 and 200.
Now i want taht a certain loopbackadress is propageted to both areas.
i tried with two ospf prozeßes and configured the lo-interface in both prozeßes
on withe area 100 - the other with area 200.
i had no problem to configure this - but the lo-address was only propagated into one area ?
How can i achive this ??
Any idea ?
Thanks for an answer !

For 2 areas to communicate they have to go through area 0 which is the bacbone area. Do you have bacbone are configured ?

What we want to do is the following:
Our router has two ospf processes and we want to put one loopback-interface into both processes
looks similarly to this:
int loopback0
ip address 1.1.1.1 255.255.255.255
router ospf 1
network 1.1.1.1 0.0.0.0 area 0
router ospf 2
network 1.1.1.1 0.0.0.0 area 0
! works if one process is defined with "redistribute connected subnets"
! but this should not be necessary, right?
The reason for this is that we connect two autonomous MP-BGP-systems (carrier-to-carrier) both via OSPF over this router and need one tdp-router-id which is propagated into both networks.
Any suggestions how we should design it right?

What wrong with redistribute connected subnets? If you are worrying about unecessary type 5 generation then do it with a route-map. If you are running the latest IOS code which has a fix for CSCdp72526 then this will be automatically taken care of, no need for a route-map.
The configuration you mentioned will not work because the interface can only be configured in one ospf process and in one area.

Hi,
how would you configure getting one loopback-address (=one tdp router-id for both) into two different ospf systems?
Sample would be fine,
