using zadm is it possible to snapshot the zone and use that snapshot to create a new one? or how do I clone a zone?

I'm sorry I just found out dlc.openindiana.org/docs/osol/20090715/SYSADRM/html/gbwmc.html

I asked OVH for the prefix I should use with the IPv6 address they assigned me. In the mean time I managed to calculate that, in order to use 2607:5300:60:78ff:ff:ff:ff:ff as default router, I should use a /56 prefix, which poses that address exactly at the end of the range of available hosts in the 2607:5300:60:78:: network. But maybe my brain is

still too linked to IPv4... :)

warden, they want you to use a, franky, broken method. They really do want you to use /128 as your netmask and then add a static route to the gateway using your primary interface.

You *can* create a point-to-point Ethernet link.

nomad: ok, but what I cannot understand is how the heck I can use their gateway if it's outside my subnet's range of addresses... in their docs I read to add a static route to reach the gateway address (Linux examples), but I wasn't able to apply it in OmniOS

warden, I haven't had to deal with that kind of braindeath so I can't give you any further advice.

I don't *thinking* using a /56 will be a problem... unless you need to access any of those specific hosts for some reason.

but their documentation doesn't support doing that.

TGH, I'm utterly unimpressed but I'm not the customer they're looking for.

I just received their reply... I asked them if to use a /44 prefix was ok: "we cannot review the configuration you've provided, as we're unfamiliar with the software you're using"! :S

yeah, a /44 would be a bad idea.

stick with the /56.

Using /44 would mean you can't talk with anything else on their network.

Thanks, I'll surely go with the /56 prefix... and keep learning by encountering potential issues in the future! :)

warden: if you tell certain network stacks that a particular address is on-link, it will assume it's on-link and attempt to use ND/ARP to reach it

even if it's outside the range of "local" addresses where (addr&netmask) == (your_addr&netmask)

you mean that at worst I won't be able to reach and being reached from other hosts in the same /56 prefix range, don't you?

warden: you can set it up the way they're expecting with route add -interface

configure interface with a static /128

then: "route add -inet6 -interface <routeraddr>/128 <myaddr>"

then: "route add -inet6 default <routeraddr>"

and you avoid the problem with the overly-wide prefix.

sommerfeld: wow... it works, and I'm able to reach my neighbors in the same IPv6 /56 prefix range!

Thank you so much! I tried to do that but i missed the right sequence of the "-iface" parameter

we probably need another example in the man page for this config

I failed because I was adding an interface name like this: "-iface igb0" as was used to do in FreeBSD! :'(

yes, we should be able to name the interface directly instead of indirecting through one of its local addresses.

warden: I filed illumos.org/issues/16968

→ FEATURE 16968: route(8) should have an IPv6 -interface example (New)

omnios has one IPv6 related bug - dhcpd fails to start on boot if global prefix is used in config, because ip interface will take time to get global prefix. The error is: No subnet6 declaration for ixgbe0. svcadm clear is fixing it once the interface has global address:)

Great! Thank you for the precious help and the patience in examining my particular setup. My journey to learn illumos/OminOS has been wonderful so far, also because of its friendly community!

tsoome_: not unique to omnios, and not unique to dhcpd (I've run into the same issues with named and postfix on openindiana mentioning globals in config if the router is having a bad day...)
