There's certainly a bunch of NBMA network media out there. The problem is abusing the routing table next hop as a way to specify the remote tunnel endpoint. This should be an attribute of the gif interface, configured outside of the routing infrastructure. Or, perhaps treated like ARP for ethernet; it's just an accident that the "MAC" address for a multi-point NBMA tunnel is an IPv4/IPv6 address. louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
