IPv6 link-local routes disappear in 6.2-RC1

[Daniel Dvořák]

Hi all,

 

I want back ipv6 link-local routes back, do you know how to do that ? I hope this significant change will be in release document for 6.2. I did not change rc.conf since release FreeBSD 6.1 in May06.

 

This is STABLE RELENG_6, kernel from 28.8.2006 and it is OKAY:

 

server1# uname -a

server1# netstat -rn

This is still STABLE RELENG_6, but it shows as 6.2-PRERELEASE, kernel from 2.10.2006 and it is still OKAY:

This is STABLE RELENG_6_2, 6.2-RC1, kernel from 18.11.2006 and it is NOT okay:

 

server3# uname -a

How can I get backs link-local routes in RELENG_6_2 and which changes in code it causes or brings about.

 

I appeal our documentation maintenaner to write some lines about this strange from my point of view change.

 

Bye
