Re: BGP Prefix List Question [7:47117]

Easy enough

ge = greater than or equal to

le = less than or equal to

10 is greater than or equal to 1,2,3,4,5,6,7,8,9,10

10 is less than or equal to 15,14,13,12,11,10

in your example, you are stating that you want to permit subnets of
11.11.11.0/24 with some value. If you were to say ge 26 le 30 then this
would permit any subnet of 11.11.11.0 with a subnet mask of /26, /27, /28,
/29, or /30

It takes a little study to get the idea. the command reference on CCO is
worth spending some time with. Even better is to set up a couple of routers,
put a whole bunch of different subnets on one of them, and filter the routes
to the other router using a prefix list. after a while spent looking at the
routing tables, you will get the idea.

 Could someone explain to me what the ge and le options are used for in
a
 prefix list statement?
 Example: ip prefix-list MYLIST permit 11.11.11.0/24 ge le

 Thanks!

I have developed a method.

I draw a generic rule like this:

lenge-value---le-value---32

For the command  ip prefix-list MYLIST permit prefix/24 ge 25  I put  that
values on the rule:

len=24
ge=25 (values greater than 25 marked with *)
le= not present

2425***32

So the command ip prefix-list MYLIST permit prefix/24 ge 25 match the
prefix length from 25 to 32.


For the command  ip prefix-list MYLIST permit prefix/24 le 28  I put  the
values on the rule:

len=24
ge= not present
le= 28 (values lower than 28 marked with *)

24***2832

So the command ip prefix-list MYLIST permit prefix/24  le 28 match the
prefix length from 24 to 28.

===
Finally for the command  ip prefix-list MYLIST permit prefix/24 ge 25 le
28. I put  the values on the rule:
len=24
ge=25
le=28

24--25***28--32

So the command ip prefix-list MYLIST permit prefix/24  ge 25 le 28 match
the prefix from 25 to 28.

Ok...I understand. The book I have here did not explain it very well. I will
definately play around with it in the lab to get a better idea. Thanks!
