Hi,
Thanks for looking! Yes, they are the same. However, I
dont see this error on the other box which does not have ipv6
negotiation on the line (set bundle enable ipv6cp). Only since
enabling ipv6 negotiation and oddly enough only after a few days did
the error start happening.
# Create clonable bundle template named B
create bundle template B
set iface idle 1800
set iface enable tcpmssfix
set ipcp disable vjcomp
set bundle enable ipv6cp
set ipcp deny vjcomp
set ipcp ranges xx.yy.zz.6/32 ippool pool1
#set ipcp nbns 127.0.0.1
# Set bundle template to use
create link template L l2tp
set l2tp disable dataseq
set link action bundle B
# Enable peer authentication
set link disable eap
set link enable pap
set link disable acfcomp
set link disable protocomp
set link disable check-magic
set link deny acfcomp
set link keep-alive 10 60
set link deny protocomp
load radius
set link mtu 1492
set link mru 1492
set link enable incoming
set link disable peer-as-calling
I also noticed that the odd time I see as a result of
ifconfig
ifconfig: ioctl(SIOCGIFAFLAG_IN6): Device not configured
ifconfig: ioctl(SIOCGIFINFO_IN6): Device not configured
The other issue I noticed was that the link local ipv6 stopped
working on a test machine.
eg
pinging the multicast address on the local link stopped working for some reason
ie ping ff02::1%ng155
stopped working on a machine I was testing just the day
before. Killing the l2tp session and having it reconnect fixed the issue.
OK, another issue I am seeing. The routing table seems to have "junk"
in it. eg
fe80::21b:21ff:fe53:ca87%ng77
link#84 UHS 0 0 16384
lo0
fe80::%ng78/64
link#85 U 0 0 1448
(H<E9><BF><BF>x~^F(<A6>l^N(<80>SL^G<A0>V (<A0>`
(^A
fe80::21b:21ff:fe53:ca87%ng78
link#85 UHS 0 0 16384
lo0
fe80::%ng79/64
I will send a you a full copy offlist
