NetBSD, ipv6, and linode

[Michael Parson <mparson%bl.org@localhost>]

While I've got some free time over the holidays, I thought I'd go ahead
and finally try to get my NetBSD/Linode going with its assigned IPv6.

Linode tells me that my IPv6 IP is 2600:3c00::f03c:91ff:feae:c95d/64 and
my default gateway should be fe80::1.

I've tried bringing this up with static entries in /etc/ifconfig.wm0 by
appending the line:

inet6 2600:3c00::f03c:91ff:feae:c95d prefixlen 64 alias

And by adding 'defaultroute6=fe80::1' to /etc/rc.conf.

No errors, but I can't seem to ping6 or traceroute6 anywhere.

I've tried configuring it via SLAAC as per the NetBSD ipv6 page by
setting the appropriate option in /etc/rc.conf:

ip6mode=autohost

and adding '!rtsol wm0' to /etc/ifconfig.wm0

Again, I get an IP, an ipv6 default route (which I can ping6), but can't
ping6 something like say, google.com, or netbsd.org:

$ ping6 netbsd.org
PING6(56=40+8+8 bytes) 2600:3c00::f03c:91ff:feae:c95d -->
2001:470:a085:999::80
^C
--- netbsd.org ping6 statistics ---
2 packets transmitted, 0 packets received, 100.0% packet loss

I know next to nothing about ipv6 other than what I've read in the FAQs,
so, any pointers to additional debugging would be appreciated.

Thanks.
