what is the diffrence between acl and distribution list?

Hello,

is this an exam question ? Have a look at this thread, which provides an excellent explanation:

Difference between ACL , Distribution list and route map

It's not exam que.. well we can also filter the traffic using acl asn same acl we have to apply on distibution list then what is the purpose of using acl.

Hello,

not really sure what you are asking: the distribution list uses an ACL the same way a route map uses an ACL. The distribution list is basically just a container for the ACL, by itself it has no function, the same as an empty route map.

Is this what you are asking ?

Hello

An ACL are control lists  that can specify prefixes ( that is routes or subnets of routes)  via ip protocol suite or independently( tcp/udp/icmp) on either source or source and destination addressing

With these acl;s you can grant/deny access on a interface either ingress( inbound) or egress outbound)or both and you can also use them in conjunction with other stanza' like

Class-maps( for Quality of service, control plane policing)

Route-maps can use acls for policy basing routing or with IGP/EGP routing protocols to filter or advertise routes

Distribute-lists again  can be used in routing protocols to match on the acls themselves or to use route-maps which in-turn can be made to match on these acls and/or other criteria to obtain the necessary filtering etc.. you which to implement.

I have only given a very small summary on the above, if you wish to delve further  I would suggest checking the cisco cco documentation to find a more granular explanation
