Hi Everyone,
At least with Mikrotik & quagga I understand that a ptmp area means Hellos are propagated by multicasts to 224.0.0.5, the neighbors form ptp relations with each other after they have found themselfs.
with my configuration, Bird doesn't send out multicasts, evenso its logging "ospf1: HELLO packet sent via eth0"
Hi BIRD supposes that PtMP interfaces are non-broadcast and send Hellos as unicast to configured neighbors. That is how it is specified in RFC 2328: On Point-to-MultiPoint networks, a router sends Hello Packets to all neighbors with which it can communicate directly. These neighbors may be discovered dynamically through a protocol such as Inverse ARP (see [Ref14]), or they may be configured. You can try to use PtP mode, that uses mulicast Hello and i think we do not limit it to one neighbor. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
