inspired by this article, I decided to implement IPMP + IPv6 in Solaris 10.
It worked for me only this way:
1. Setup
Code:
# cat /etc/hostname*
10.23.10.113/24 broadcast + group data failover up <- hostname.e1000g0
0.0.0.0/24 broadcast + group data -failover deprecated up standby <- hostname.nxge3
group data -failover up <- hostname6.e1000g0
group data -failover up <- hostname6.nxge3
2. Testing
Code:
# if_mpadm -d e1000g0
Offline failed as there is no other functional interface available in the multipathing group for failing over the network access.
3. Fixing (I guess you can just pick random free IP)
Code:
# ifconfig nxge3 10.23.10.114/24 broadcast + group data -failover deprecated standby up
4. Again testing
Code:
# if_mpadm -d e1000g0
It works!
5. Even more - plubing back 0.0.0.0 on this NIC
Code:
# ifconfig nxge3 0.0.0.0/24 broadcast + group data -failover deprecated standby up
# if_mpadm -d e1000g0
And it magically again works!
How could it be? Why it didn`t work, when I plumbed it with 0.0.0.0 IP originally? And worked after I plumbed some real IP, and also worked when I reverted it back to 0.0.0.0?
root# cat /etc/default/mpathd
#
#pragma ident "@(#)mpathd.dfl 1.2 00/07/17 SMI"
#
# Time taken by mpathd to detect a NIC failure in ms. The minimum time
# that can be specified is 100 ms.
#
FAILURE_DETECTION_TIME=10000
#
# Failback is enabled by default. To disable failback turn off this option
#
FAILBACK=yes
#
# By default only interfaces configured as part of multipathing groups
# are tracked. Turn off this option to track all network interfaces
# on the system
#
TRACK_INTERFACES_ONLY_WITH_GROUPS=yes
When I do simple nslookup it does not generate any query for IPV6 (AAAA). But sometimes I see DNS query for both A and AAAA are generated. What decides this? The reason I do not want AAAA query is in most of the cases AAAA records are absent. Hence, if one DNS server fails, the clients keeps... (1 Reply)
I want to find out the DHCPv6 server's ip address in the network. I went through the lease files but could find only duid/server-id and not the IPv6 address of the dhcp server. And I couldn't find any commands to get that information. Is there a way to get the DHCPv6 server's IPv6 address?

Hello all,
I am trying to receive (tcp/udp/sctp) traffic from all IPs and, eventually, all ports of an IPv6 address block using as few sockets as possible short of implementing my own network stack.
One possible solution was to associate an IP block to an interface then bind to that... (6 Replies)
Hi All,
Would anyone know how to modify the below, so only the IPv6 address (red) is printed, please?
(in other words, what's between inet6 and the / sign)
ipv6=`/sbin/ifconfig lo0:5 inet6 | grep 'inet6'`
print $ipv6
Currently the output of the above script is:

Hi,
Am using FreeBSD7.4/i386
During IPv6 configuration, I added the following in rc.conf as

Is my proceeding right??
