Prefix list issue

Hi all,

What means of ip prefix-list cisco seq 10 permit 0.0.0.0/0 le 19

The address range is (1.0.0.0 - x.255.224.0) ?

Re: Prefix list issue

HI,

It should match anything network with subnet mask less than or equal to 19 bits.

Re: Prefix list issue

Hi,

ip prefix-list XYZ permit A.B.C.D/24 le

/24 will check to match the prefix and Mask will check the mask of the prefix. So if you have configured as,

ip prefix-list xyz seq 5 permit 210.177.168.0/24 le 32, it matches all the prefix with 210.177.168. (3 octects) and the mask can be anything le 32.

ip prefix-list xyz seq 5 permit 210.177.168.0/24 le 32

=> anythin frm 210.177.168.1 - 210.177.168.255 will be permitted.
