Distribute-list

[fujin.huang]

Hi,

If I have a distribute-list:

CASE1:

distribute-list 1 in

access-list 1 permit 10.1.0.0 0.0.255.255

Am I right to say that this will allow 10.1.0.0/16, 10.1.1.0/24, 10.1.2.0/24, and so on. As long as the network prefix matches 10.1.x.x.

CASE2:

distribute-list 1 in

access-list 1 permit host 10.1.0.0

Am i right to say that will allow 10.1.0.0/16, 10.1.0.0/17, 10.1.0.0/18, and so on. As long as the network prefix matches 10.1.0.0

My question is if I want to allow 10.1.0.0/16 only, what should I configure?

Thanks for the help

Fujin

If you want to match exact prefix route,try to use prefix-list,like the below.And before deploying it,make sure whether the IOS support.

ip prefix-list test permit 10.1.0.0/16

router eigrp/rip/igrp [as-num]
