Anybody have tested the Lab#2 from the book CCIE Security Practice Labs by Yusuf Bhaiji? There is an ospf redundancy configuration using HSRP and GRE tunnels. The objective was to create only one adjacency at a time between two OSPF neighbors. The testing was successful until such the time when I redistributed the BGP into OSPF on the two routers. Initially the route to the network outside the AS gets failed over, but when I try to bring up again the interface on the Priority router, the route to the AS no longer comes up. I had to do a "clear ip bgp *" on the other router just to restore the connection.
If any body has done this please help to figure out. Thanks a lot!
I can send the crude network diagram for the asking.
