Hello all: I'm using FreeBSD-4.8-RELEASE. (I've tested the same thing using a KAME snap, so I CCs to them :) I've got two routers sending RAs on the same link, so the host is configured with two IPv6 prefix on the same NIC. Watching the routing table I only see one default IPv6 route. When I try to ping the global IPv6 address of one router, if I'm lucky and the router is the same router which I've got installed on the default route, it will answer. The problem is that the host doesn't seem to realize that it is on two links at the same time, so it always sends packets to the default router.... For example, if there's only one RA, the autoconfiguration process ends up with a link-route like this: 2001:720:410:1001::/64 link#2 UC fxp0 On the other hand, when there are 2 RAs on the same link, this route doesn't exist ! Is this behaviour right ? I've observed the same thing on Linux... -- JFRH
