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: santi...@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."
