I have the topology below:
On the network
10.11.9.0/24 (Area 3), I want to allow only traffic to the Internet.
How would I go about this as I was thinking denying traffic to all my network and allow it for everything else.
Here are the commands I entered in R2, but they do not seem to work:
access-list 100 deny ip any 10.111.0.0 0.0.240.255 access-list 100 permit ip any any ! interface GigabitEthernet0/0 ip access-group 100 out !
These commands don't seem to work, but could it because of another reason like OSPF?
Should I be allowing everything to the ISP and denying everything else? How would I go about this?
