System: NetBSD starbuck.13thmonkey.org 1.5ZC NetBSD 1.5ZC (config.starbuck) #0: Tue Mar 26 14:02:50 CET 2002 imago@starbuck.13thmonkey.org:/usr/sources/cvs.netbsd.org/src/sys/arch/alpha/compile/config.starbuck alpha

>Description:
The rtk interface seems to have trouble with recieving multicasts needed
for IPv6 for its `ndp'.

Typical issues are :
13:22:54.034857 starbuck.13thmonkey.org > ff02::1:ff8f:abd5: icmp6: neighbor sol: who has paalhuis.13thmonkey.org
13:22:55.034793 starbuck.13thmonkey.org > ff02::1:ff8f:abd5: icmp6: neighbor sol: who has paalhuis.13thmonkey.org

but this machine who is on the _same_ network and just doesn't answer. If i 
log in onto this machine and use a `tcpdump' without the -p option it 
spontaniously reacts and the `starbuck' machine gets its response.

>How-To-Repeat:
It allways happends :(

>Fix:
There is a quick HACK to make it work .... i'm now trying this patch out 
and all seems to work fine now (thanks soda).....
