I am currently trying to setup static ipv6 address with a persistent default gateway. This is on a Solaris 10 non global zone running inside a Solaris 10 global zone. My production server I am comparing against is a Solaris 10 xen instance running on a Oracle Solaris xen instance.
I have got it working but not as intended. I am dont understand why when i plumb the interface and it comes online with the assigned ip that it also created another 2 interfaces igb1:2 and igb1:3. Why does this happen?
I thought that was the job of ndp to stop auto configuration. My /etc/inet/ndpd.conf file with 644 perms.
Here are the steps I have performed in the following order.
1. created ndpd.conf file with above configuration.
2. Enabled ndp "svcadm enable ndp"
3. vi /etc/hostname6.igb1 to include the below config
addif x:y:z:1001::41/64 up
4. ifconfig igb1 inet6 plumb
5. ifconfig igb1:1 inet6 plumb
6. ifconfig igb1:1 inet6 x:y:z:1001::40/64 up
below is my ifconfig output
Code:
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
igb1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet x.y.z.41 netmask ffffff00 broadcast x.y.z.255
ether 0:21:28:75:dc:1
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
inet6 ::1/128
igb1: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2
inet6 fe80::221:28ff:fe75:dc01/10
ether 0:21:28:75:dc:1
igb1:1: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2
inet6 x:y:z:1001::41/64
igb1:2: flags=20a0841<UP,RUNNING,MULTICAST,NOLOCAL,ADDRCONF,IPv6> mtu 1500 index 2
inet6 subnet x:y:z:1001::/64
igb1:3: flags=20a0841<UP,RUNNING,MULTICAST,NOLOCAL,ADDRCONF,IPv6> mtu 1500 index 2
inet6 subnet x:y:z:1001::/64
We have this implemeneted on a production server. However, that server does not show they igb1:2 and igb1:3 interfaces. I can ping the gateway and the default route. I just dont think the :2, :3 interfaces should show up.

I don't know how you've managed to get these interfaces configured (plumbed) but, hopefully, I'll write a few things that may help. This may help you investigate **or provide additional info to us**
THIS IS FOR SOLARIS 10 ONLY
A booting Solaris operating system tries to plumb interfaces if it find files
Code:
/etc/hostname.*
** post the output of
Code:
ls -l /etc/hostname.*
**
hostname.* files contain just the hostname that the system should be seen as on that particular interface.
That host name is resolved to an ip address (usually by looking in /etc/hosts or /etc/inet/hosts for ipv6) and that ip address is used on that interface.
If you have extraneous plumbed interfaces try moving the hostname.* file(s) out of the way by renaming them (mv).
Being sysadmin professionals here never delete anything, just rename.
Reboot the system and see if it comes out with any complaints/errors.
If so, post them here.
When I restart the zone it comes up with igb1:1, igb1:2, and igb1:3. Everything works ok. But I dont think it should show the igb1:2 and igb1:3 interfaces.
So I have also tried to add the following to my /etc/hostname6.igb1 configuration.
Code:
x:y:z:1001::41
addif x:y:z:1001::41/64 up
This does now not give me two extra interfaces igb1:2 and igb1:3. However, now I cannot ping my default route. It appears I am missing the routes that get automatically populated via the first mechanism I spoke about.
My question is what am i missing to configure this to work without getting the additional interfaces? I dont see these extra interfaces in our production server. Below is the working netstat output from a working server with only one interface plumbed igb1:1.
Code:
Routing Table: IPv6
Destination/Mask Gateway Flags Ref Use If
--------------------------- --------------------------- ----- --- ------- -----
x:y:z:1004::/64 z:y:z:1004::9 U 1 41 xnf0:1
fe80::/10 fe80::216:3eff:fe45:c0c7 U 1 0 xnf0
ff00::/8 fe80::216:3eff:fe45:c0c7 U 1 0 xnf0
default x:y:z:1004::14 UG 1 4587
::1 ::1 UH 1 0 lo0

A booting Solaris 10 operating system will take it's default route for ipv6 operation from
Code:
/etc/defaultrouter6
This should contain just the ip address of the gateway to which all lan external requests should be sent (assuming there is only one route configured).
Take a look at that.
If the file doesn't exist you can create it with just the gateway ip address on the first line, left justified.
I dont have a /etc/defaultroute6 file on my working production server. My test server I am trying to get this working on I added a persistent route via.
Hello Dears ,
please I need your support I have Oracle Solaris 10 X86 server please if you can advise how can I add IP v6 on my server and if IPv6 was disabled how can i enable it also how can i add two IP (v4 and v6) on the same interface or I have to add another interface .
Thanks in... (1 Reply)
I am trying to setup an IPv6 network.
I modified the interfaces file:
/etc/network/interfaces
# The loopback network interface
auto lo
iface lo inet loopback
iface etho0 inet static
address 2620:7:a000::1
netmask 64
gateway ::ffff:c0a8:101

Hi,
I have created a bonding bond1 interface with 6 Eth , mode=4. Recently i have changed my old ipv6 to new one and tried to restart as well as reload network service.

my problem: i want to change from ipv4 to ipv6 on my home network.
On hpux i can assign only address non routable as fe80::1 fe80::3 etc to my lan0
Editing netconf-ipv6 i can assing a routable ipv6 address like
fd55:282f:3b98::/48
or
2001:470:26:307:89a0:aba1:f98b:eb3e

Hello,
I was wondering if it would be possible to run two VMs one with services for IPv4 and the other one with services for IPv6. The main physical system would be connected to a IPv6 switch.
I think it should be fine but I would like to hear out your comments. (1 Reply)
I am trying to capture the ipv6 packets through pcap utility.
For that i am redirecting the ipv6 packets to the loopback address , but the ipv6 packets are not getting redirected to tha loopback address.Instead they are taking there normal routes. (1 Reply)
Hello guyz..
did some of u have implement or making a testbed for IPv6?
if yes, can u attached the procedures and standard guidelines because i really need for my proposal..
thanx.. (2 Replies)
