What technique should be used on BGP edge routers to prevent a multi － homed autonomous system from becoming a trans it system?()
A. Advertise with a high MED value all networks that are discovered via external BGP.B. Set the no - export community attribute on all networks that are advertised externally.C. Remove the AS - Path information on all routes in the BGP table pr ior to advertising externally.D. Set the origin code to incomplete for all networks that are discovered via external BGP.E.

A router has two paths to reach another network in a different autonomous system. Neither route was generated by the local router and both routes have the same default weight an d local preference values.Which statement is true about how BGP would select the best path?（）A. To influence one route to be preferred, its default local preference value will be changed via the use of the command bgp default local - preference 50B.
