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.

Re: BGP Prefix List Question [7:47117]
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. -- Eng.

Re: BGP Prefix List Question [7:47117]
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! Dain.
