Are the 20 different neighbours on separate ifnets i.e. separate distinct interfaces as FreeBSD's ifconfig(8) reports them? If so, we have a problem. XORP in particular uses a single raw socket where possible to deal with the raw-ip needs of a routing protocol, usually OSPF. If there is a hard-coded limit of this kind then this is obviously going to break OSPF when configured with more than 20 peers with distinct and separate ifnet paths. I'm curious about why you have 20 ifnets. Do you really have this many physical interfaces, or are you using vlans / some kind of VPN encapsulation? Regards, BMS
