route-filter 172.22.135.0/8 orlonger reject;
route-filter 172.22.135.0/24 orlonger accept;
}
then reject;
}
term 2 {
from {
protocol isis;
route-filter 10.0.0.0/8 longer;
route-filter 10.0.0.0/24 longer accept;
}
then reject;
}
}
— Exhibit —
You are asked to block the 10.0.0.0/8 IS-IS routes from being redistributed into other protocols.

You still want the existing 10.0.0.0/25 IS-IS routes to continue to be redistributed. You have

redistributed.
