Synchronization states that a BGP router with synchronization enabled will not advertise iBGP-learned routes to other eBGP peers if it is not able to validate those routes in its IGP.
> Assuming that IGP has a route to iBGP-learned routes, the router will announce the iBGP routes to eBGP peers (thus you'll have to redistribute BGP into IGP to have it working).
> Otherwise the router treats the route as not being synchronized with IGP and does not advertise it.
The best practice is to disable synchronization but have all routers in the network running BGP, and accordingly full meshed (or use a RR or Confederation) accordingly routing loop and back holes are prevented
