Re: Filter list and access list?

 A prefix list is used to filter prefixes...

A filter list is used in BGP to call an as-path access list and filter
based on AS Path information.

They're both methods of filtering, just different pieces in different
places.

  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
