A show bgp policy route-policy command also exists, which runs all routes in the RIB past the named policy
as if the RIB were an outbound BGP policy. This command then displays what each route looked like before
it was modified and after it was modified, as shown in the following example:
show rpl route-policy test2
route-policy test2
if (destination in (10.0.0.0/8 ge 8 le 32)) then
set med 333
