Question
Click the Exhibit button. user@router# show policy-options policy-statement isis-export { term 1 { from { 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; } } 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 applied an export policy as shown in the exhibit, however, the 10.0.0.0/8 routes are still being redistributed. What is causing the problem?
