Hehehehe... Well, now that we know the underlying problem, let's go back to the lab and uncover what went wrong here (nothing wrong with the lab). :)
Task 7.6 "6) Create a loopback interface on R8 to use the subnet of 8.8.8.1 /24. Enable OSPF between R7 and R8 (150.50.5.64) and on the newly created loopback interface on R8. Make the loopback interface a point-to-point OSPF network. Have R8 redistribute the Ethernet (150.50.4.0) subnet into OSPF. Ensure that all BGP speakers in AS200 have subnets 8.8.8.0 and 150.50.4.0 in their BGP tables. Subnet 150.50.5.64 should not be in any routers BGP table. You are not allowed to use the "network" command or "redistribute connected" command under BGP." So you're following the basic parts there, except you're running into redistribution logic problems along the way... On R8, type in: Router ospf 100 no redistribute connected subnets redistribute connected route-map Conn subnets access-list 1 permit 150.50.4.0 0.0.0.255 route-map Conn permit 10 match ip address 1 And see what happens next!
