Hello, Ondrej! There was something wrong with my previous test. So I did new one. Answering your questions: 1) Where interface is broadcast and mode is ptmp - bird does not send any packet (checked with tcpdump) but with "debug all" there are messages "<TRACE> main_ospf: HELLO packet sent via em0" every tick. 2) Yes, if neighbors are configured ptmp works as expected. Without neighbors configured it even does not learn neighbors from incoming packets. 3) I read FreeBSD related post, but 1.6.3 is official port for FreeBSD and it includes patch: +#if (defined __OpenBSD__) || (defined __DragonFly__) || (defined __FreeBSD__ && (__FreeBSD_version >= 1100030)) + /* Different BSDs have different expectations of ip_len endianity */ ip->ip_len = htons(ip->ip_len); #endif 4) There really are no problems with mode == broadcast * Hello To which address it sends the Hello packet? To the first learned neighbor? What you see in logs if you enable 'debug all' for OSPF? What is shown by 'show ospf neighbors'? Note that BIRD expect that you specify neighbors in 'neighbors' section for NBMA or PTMP modes, but it would learn neighbors from received Hello packets. * * There were people reporting problems in FreeBSD 11 due to API change, but that would affect also broadcast mode: https://www.mail-archive.com/bird-users@network.cz/msg01542.html -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago at crfreenet.org <http://trubka.network.cz/mailman/listinfo/bird-users>) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so." -- С уважением, Борис Коваленко
