any ideas ?

hadi

hey,

 

why am i getting this error ?

 

Rack1R2(config)#ip prefix-list TASK_5.10 deny 129.1.0.0/16 le 16
% Invalid prefix range for 129.1.0.0/16, make sure: len < ge-value <= le-value

 

i mean my len which is eq 16 is <= to my le-value which is also 16

 

 

thx,

hadi

What prefix length are you trying to match? if you want to match that specific address 129.1.0.0/16 then you dont need "le".  if you want to match range of netwoks then you le number must be greater than your mask .... /16 le 24 for example.  If you want to match that exact subnet then use 129.1.0.0/16 only.

make sure: len < ge-value <= le-value ------ OK ge-value is what is compared to <= to le ... ONLY if you are using GE and LE in the same prefix

In your case you are using only LE value which must be greater than LEN value otherwise you are trying to match /16 where you dont need LE keyword.
