如何判斷 wildmask
各位先進你們好: 想請教大大幫忙有一standard ACL 如下:
access-list 2 permit 10.10.0.10
access-list 2 pdeny 10.10.0.0 0.0.255.255
access-list 2 permit 10.0.0.0 0.255.255.255
interface FastEthernet 0/0
ip access-group 2 in
在第一條的ACL 我怎得知它是哪一個 wildmask. 我只知道它是一個 IP.
因為在正確答案里提到,From the 10.10.0.0 subnet, only traffic sourced from 10.10.0.10 is allowed; traffic sourced from the other 10.0.0.0 subnet also isallowed.
所以代表 10.10.0.10 的 wildmask 也是 0.0.255.255? 如何判斷?
謝謝大大指教
