<blockquote>
A distribution list is actually a misnomer and does not really belong here A distribution list is really only a command that uses route-maps or ACLs to perform filtering of routing information advertised or received within a particular routing protocol. It is not a standalone filtering mechanism similar to ACLs/route-map.

I was exactly at that link before I posed the question..<br />
it is a little bit helpful...but they don't elaborate on the difference..for instance &nbsp;Distribute list can be use the same way as the Access-group &nbsp;when applied at the Interface level..<br />
<br />
I want to know the similarities and the differences between..<br />
Access-Group and Distribute-List
</div>


<div>
Can you provide an example of the distribute list command being used at the interface level?
</div>


<div>
I meant for Interface ..<br />

Router(config-router)#<b>distribute-list 3 in fastethernet0/0</b><br />
<br />
Creates an incoming distribute list for interface FastEthernet0/0 and refers to ACL 3<br />
<br />
Router(config-router)#<b>distribute-list 4 out serial0/0/0</b><br />
<br />
Creates an outgoing distribute list for interface Serial0/0/0 and refers to ACL 4<br />
<br />
Router(config-router)#dist<wbr />ribute-lis<wbr />t 5 out ospf 1<br />
<br />
Filters updates advertised from OSPF process ID 1 into EIGRP autonomous system 10 according to ACL 5

Access-List and Distribute-List<br />
Access-Group in/out and Distribute-List in/out<br />
<br />
<br />
I have seen examples where they use an Access-List to determine the traffic to be Permitted or Denied, then you go to the interface and they use the Access-group command to alllow in/out the traffic<br />
<br />
I also have seen Distribute-List &nbsp;in /out that does pretty much the same thing. I would like to know where each command differs from other.<br />
<br />
Access-group in/out can be used at the interface level only<br />
Distribute-List in/out, at interface level &nbsp;and global config level<br />
<br />
<br />
Thank you

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
