Hi Juan,

 On top of Truman's suggestion, I'd say you might want to think about
different 'default' behaviors between IOS and JUNOS; such as
sending/receiving communities. Unlike IOS, JUNOS will send the
community information on bgp updates by default, so if you'd like to
'keep your communities to yourself', you should have your BGP-OUT
policy as follows:

##
policy-options {
    policy-statement BGP-OUT {
        term dont-send-communities {
            then {
                community delete all;
                next term;
            }
        }
        term local-pref {
            from {
                prefix-list BGP-OUT;
            }
            then {
                local-preference 104;
                accept;
            }
        }
        term default {
            then accept;
        }
    }
    community all members *:*;
}

As a registered Juniper customer, you should also have access to I2J
translator tool, available via the following URL:
