Re: Filter list and access list?

It is to avoid blocking traffic from another int/network because it is only checking the src IP addr?

I'm not entirely sure about this though...

Item c, really??

Don't understand why a standard acl would be placed close to the destination as possible when the spource ip is what is configured in the acl. Thot the best practice with filtering was to place the acl as close to the source as possible, regardless of acl type.

Re: Filter list and access list?

Raj,

a) In Standard ACL, filtering is based on source IP address.
where as in extended ACL, filtering is bases on Source IP
address, Destination IP address, Protocol Type, Source Port
Number & Destination Port Number.

b) Standard ACL are used to block particular host or sub
network. where as Extended ACL is used to block particular
services.

c)Standard ACL is implemented as possible closer to
destination. where as Extended ACL is implemented as
possible closer to source.

d) Standard ACL is created from 1 - 99 & extended range 1300
- 1999. where as Extended ACL is created from 100 - 199 &
extended range 2000 - 2699.

e) In Standard ACL, two communication will be blocked, where
as in Extended ACL, one way communication will be blocked.

f) In Standard ACL, all services will be blocked. Where as
in Extended ACL, particular services wil be blocked.

g) A filter list is used within routing protocols to filter specific
prefixes
