JN0-104 Exam - Question 43


You are creating a new routing policy on your Junos device. You are currently receiving multiple routes within the 10.10.10.0/24 subnet from the same upstream

BGP neighbor. Your policy should only allow the 10.10.10.0/24 route and reject all other routes within that /24 range. Referring to the exhibit, which route filter match type would satisfy this requirement?

Show Answer
Correct Answer: C

To allow only the 10.10.10.0/24 route and reject all other routes within that /24 range in your routing policy, you should use the 'exact' route filter match type. The 'exact' match type ensures that only the specific route 10.10.10.0/24 is accepted, and any other routes within that range will be rejected. This matches the requirement perfectly.

To allow only the 10.10.10.0/24 route and reject all other routes within that /24 range in your routing policy, you would need to use the "exact" route filter match type. The "exact" match type in a route filter allows you to specify an exact prefix match. In this case, you want to match only the specific route 10.10.10.0/24 and reject any other routes within that subnet. Therefore, the correct route filter match type to satisfy this requirement is: C. exact

[cont.] to allow only the 10.10.10.0/24 route and reject all other routes within that /24 range, if the term in the routing policy ends with "then reject", it would effectively reject any route that does not match the exact prefix 10.10.10.0/24. Any other routes within the 10.10.10.0/24 subnet would be rejected. So, regardless of the route filter match type used in the term, if the term ends with "then reject", it will reject any route that does not match the specified conditions, in this case, any route outside the 10.10.10.0/24 prefix.
