ACL Access Control List

(1) effects:

IP Access-list extended to-Internet

Permit IP host 10.63..1 .1 any

Permit IP host 10.63..2 .2 any

Permit IP host 10.128.16.1 any

Permit IP host 10.128.16.2 any

Analysis:

The displayed result indicates that the vro has created an extended ACL named "to-Internet" so that:

Allow all IP traffic from the host 10.63..1 .1 To access the Internet through the router)

Allow all IP traffic from the host 10.63..2 .2 to access the Internet through the router)

Allow all IP traffic from the host 10.128.16.1 to access the Internet through the router)

Allow all IP traffic from the host 10.128.16.2 to access the Internet through the router)

 

(2) configurations required on the vro:

Router (config) # IP Access-list extended to-Internet

Router (config-ext-NaCl) # access-list 110 permit IP host 10.63.201.125 any

Router (config-ext-NaCl) # access-list 110 permit IP host 10.63.201.136 any

Router (config-ext-NaCl) # access-list 110 permit IP host 10.128.16.209 any

Router (config-ext-NaCl) # access-list 110 permit IP host 10.128.16.216 any

 

Next, apply the ACL statement to the interface (which is used according to the actual interface of the router, assuming that the ACL statement is used in interface fa0/1 ):

Router (config) # interface fa0/1
Router (config-If) # IP Access-group 110 out

 

(3) Summary: The ACL is divided into two steps. The first step is to set the ACL statement, and the second step is to apply it to the interface.
