Gaurav,

Generally we use 0.0.0.0 is allow all IP packets. The the statement at the last will deny the all traffic from any source which is not the IP traffic for example IPX trafic any any other.

Hi Amit,

Access-list 1-99 belongs to "IP standard access list" it won't look other traffics other than ip.

Am i correct?

Hi Gauravm,

The statements represents standard access lists. But these statements ara not complete. You have not defined any wild card mask.

Following link will help you understanding the access lists, their syntax and how these can be used:

Hi,

In standard access-list

any means 0.0.0.0 255.255.255.255.

Also if you are not mention any wildcard mask, 0.0.0.0 is assumed to be the mask.

I think in your ACE, you should mention 0.0.0.0 255.255.255.255.

I think i will some idea.

Hi,

With standard access lists, if you omit the mask from an associated IP host address ACL specification, 0.0.0.0 is assumed to be the mask.
