CCNA -Access Control List- Named -Part-5

0

Named access list can be Standard or Extended Access list. With named access control list we will use name I/O number. Named ACL starts with ip command. With named ACL we will block 10.0.0.2 to gaining access on 40.0.0.2. Lets configure on Router1

Access Control List-Extended

router1(config)#ip access-list extended sales
router1(config-ext-nacl)#deny ip host 10.0.0.2 40.0.0.2  0.0.0.0

router1(config-ext-nacl)#permit ip any any

router1(config-ext-nacl)#exit

router1(config)#int fastEthernet 1/0

router1(config)#ip access-group sales out

now check from  pc-10.0.0.2 it will be destination host unreachable …………………

Thanks
