AS out of range

Dear All, I don't want to advertise my network to some 1317xx, and I found the following error: /usr/local/etc/bird.conf, line 14: Value 1317xx out of range (0-65535) Does bird have AS limitation on bgp community filtering? Thank you Best regards, David S. ------------------------------------------------ e. david@zeromail.us w. pnyet.web.id p. 087881216110
