If a policy does not modify the route, by default the route is dropped.
route-policy ONE
end-policy
Whereas the following policies pass all routes that they evaluate.
route-policy PASS-ALL
pass
end-policy
route-policy SET-LPREF
set local-preference 200
end-policy
Drop statements cause a route to be dropped immediately so that no further policy processing is done. Note also that a drop statement overrides any previously processed pass statements or attribute modifications. For example, the following policy drops all routes. The first pass statement is executed, but is then immediately overridden by the drop statement. The second pass statement never gets executed.
route-policy DROP-EXAMPLE
pass
drop
pass
end-policy
