Do not the rules of synchronization say:
you must have a route to the next hop
you must have the route in your routing table
Do you have both of these? Can we see the whole routing table.
Can you do a show ip bgp 11.1.1.0 for us.
Also - you do not have any external BGP peers - so who would you send the
route to anyways if it were the best?
