Hello,
In the defrouter_addreq function in
"/net/bsd_tcpip/current/src/sys/netinet6/nd6_rtr.c" it will do a
rtrequest for the IPv6 link-local address of the chosen default router
(from router advertisements). However, I'm getting a 351 (ENETUNREACH)
error code from rtrequest. I'm wondering if maybe the ifa_ifwithnet
function (/net/bsd_tcpip/current/src/sys/net/if.c) doesn't handle IPv6
addresses properly and is causing ifa_ifwithroute to return NULL.
The interface is pre-programmed with the link local address:
fe80::80:72ff:fe00:62. I've verified this with the ioctl SIOCGIFCONF
command (it actually reports fe80:1::80:72ff:fe00:62, but that's because
FreeBSD temporarily adds an interface index after the prefix)
The router's link local address is: fe80::21f:5bff:fe00:a5cd
My debugging environment is limited for about the next week, so I'm
unable to step through the code. I've been using diag_printf(), which
is only getting me so far. I was hoping to hear if someone has gotten
this working (i.e. an IPv6 connection that uses the default gateway
determined from router advertisements), and what I might need to do to
get this to work.
Thanks,
Shaun Louie

Solved: I had programmed an all ones netmask for the link-local
interface address.
