When creating a prefix-set for a route policy to be used in BGP would the following be functionally equivalent?  Thanks!

 

192.168.0.0/16 ge 17

192.168.0.0/16 le 32

192.168.0.0/16 ge 17 le 32

They are not all functionally equivalent.

 

> 192.168.0.0/16 ge 17

prefix matches 192.168.0.0/16 and prefix-length is greater than 16

 

> 192.168.0.0/16 le 32

prefix matches 192.168.0.0/16 and prefix-length is greater than 15

 

> 192.168.0.0/16 ge 17 le 32

Functionally equivalent to the first one

Awesome!  Thanks!  I was  having difficulty with the "le 32".  I didn't realize that it was including the prefix length.  Thank you again!
