Example: Rejecting Routes from Specific Hosts

Reject a range of routes from specific hosts, and accept all other routes:



[edit]
policy-options {


policy-statement hosts-only {


from {
route-filter 10.125.0.0/16 upto /31 reject;
route-filter 0/0;
}


then accept; 
}


}

You do not use the through match type in most routing policy configurations. You should think of through as a tool to group a contiguous set of exact matches. For example, instead of specifying four exact matches:



from route-filter 0.0.0.0/1 exact
from route-filter 0.0.0.0/2 exact
from route-filter 0.0.0.0/3 exact
from route-filter 0.0.0.0/4 exact

You could represent them with the following single match:



from route-filter 0.0.0.0/1 through 0.0.0.0/4
