  • 1.  What is difference between prefix-list-filter and prefix-list?

    Hi Please see the below. What is difference between prefix-list-filter and prefix-list ? Thank you

     

    set policy-options policy-statement IMPORT_P term 10 from prefix-list-filter RFC orlonger
    set policy-options policy-statement IMPORT_P term 10 then reject

     

    set policy-options policy-statement IMPORT_P term 10 from prefix-list RFC orlonger
    set policy-options policy-statement IMPORT_P term 10 then reject

     

     

    When I type in router "C1# set policy-options policy-statement IMPORT_P term 10 from ?"

    I got the below:

    > prefix-list List of prefix-lists of routes to match
    > prefix-list-filter List of prefix-list-filters to match

     

    Anyone can explain it? Thank you

    Hi,

     

    In short using prefix-list is an exact match of prefixes in the prefix-list while prefix-list-filter allows further filtering such as 'orlonger'.

    set policy-options policy-statement IMPORT_P term 10 from prefix-list-filter RFC orlonger

set policy-options policy-statement IMPORT_P term 10 from prefix-list RFC orlonger   --> Results in syntax error

     

    Cheers,

    Ashvin
