Hi,

As per my understanding the ACLs should be like this, please correct me if i`m wrong.

for Vlan2 :

access-list 122 permit ip 10.133.9.96 0.0.0.31 10.133.0.0 0.0.0.63

access-list 122 permit ip 10.133.9.64 0.0.0.3110.133.0.0 0.0.0.63

access-list 122 deny ip any any

For Vlan 11 :

access-list 131 permit ip 10.133.0.0 0.0.0.63 10.133.9.64 0.0.0.31

access-list 131 permit ip 10.133.9.96 0.0.0.31 10.133.9.64 0.0.0.31 log

access-list 131 deny ip any any

For Vlan 12 :

access-list 132 permit ip 10.133.0.0 0.0.0.63 10.133.9.96 0.0.0.31

access-list 132 permit ip 10.133.9.64 0.0.0.31 10.133.9.96 0.0.0.31 log

access-list 132 deny ip any any
