Hi Andrey, You stated (if I may quote you freely) ... that if an AS number is returned, it might / should not impact routing ... And you are probably right for 99.8% .. However ... there might be situations where someone would be using a certain BGP community in RPLS for internal reference still while the actual AS number isn't used anymore. Think about a similar way as how certain routeserver filtering is implemented. import: from AS6777 action pref=85; accept ANY AND NOT <^[ASAAAA ASXXXX ASYYYYY ASZZZZZ ASWWWW]> AND NOT {0.0.0.0/0} export: to AS6777 action community .= {6777:6777, 6777:AAAAA, 6777:XXXX, 6777:YYYYY, 6777:ZZZZ, 6777:WWWW}; announce AS-<as-number> Erik Bais
