Hi !
Is your route active ? what is the result of "show route x.x.x.x/22 exact" ?
For advertising the /22, the route must be active. Did you generate a route corresponding to the /22 ? Exemple :
set routing-options aggregate route x.x.x.x/22
Then on your policy, you should have something like :
policy-statement SUMMARY {
from {
protocol aggregate;
route-filter x.x.x.x/22 exact;
}
then accept;
}
