Description (partial)


Missing routes in the routing table.
Missing paths in the router border table, which is visible using show command
    show ip ospf border


Router may stay without external and inter area routes under
these very specific conditions
 - router is configured with command ispf
 - router has connectivity to area 0 via virtual-link
 - non-zero area provides better path to same of the ABRs in area 0,
   therefore we can see in 'show ip ospf border' paths with flag transit
