Hi,

please help me to define a filter for the below statement,

Damp all routes below than 152.152/16 from R1 more aggressivley ?

I tried to configure on router and below is my configs ,

-set policy-options policy-statement damp1 term 1 from route-filter 152.152.0.0/1 prefix-length-range /1-/15 damping aggressive

-set policy-options damping aggressive half-life 20
-set policy-options damping aggressive suppress 2500

but it shows message like this

root@R6# commit check
[edit policy-options policy-statement damp1 term 1 from route-filter 152.152.0.0/1 prefix-length-range /1-/15]
'152.152.0.0/1'
Policy: prefix length 1 is too short for prefix 152.152.0.0, ignoring excess host bits
configuration check succeeds

So, please help ,
thanks,
r@thore

I think you have a typo:

Try this:

Thanks   

LeahLynch,

But it's not working same message it shows but really want to damp routes from /1-/15 of 152.152./16 because statement is "damp routes below then 152.152./16".

Is that true the below than /16 means /1-/15 or /17-/32 ? First of all we have to solve this query.

Waiting for more responses.

"Damp below /16" means damp all routes with mask lengths from 17 to 32.

Trust me 

On a more pedant note - "below" in this context means not "mask length less than /16" but rather "more specific than /16".

thanks Alex,

I really have confusion in the statement , so according to previous discussion can we assume the same for above keyword like,

Damp all routes above then 152.152./16 ?

So its filter ranges from /1 - /15 . Is it so ?

And if it so then how can we define its filter because when i define its filter it prompts a message which i already pasted,

root@R6# commit check
--- [edit policy-options policy-statement damp1 term 1 from route-filter
---152.152.0.0/1 prefix-length-range /1-/15]
---'152.152.0.0/1'
---Policy: prefix length 1 is too short for prefix 152.152.0.0,ignoring excess host bits

Thanks in advance.

No. The correct range is /17 - /32.

The config would be "route-filter 152.152/16 prefix-length-range 17-32"
