/60 Prefix delegation from ISP, now what?
-
Hi all,
Maybe I am crazy, isn't the point of prefix delegation to have your LAN hosts obtain addressing from the ISP? I have a /60 assigned from my ISP and now wish to "delegate" this block across my LAN. I am using VLANs and with these to remain in place an put the designator for each in the first space of the /64 range. Since a /64 is 16 networks of 0-9 and a-f I started with 1.
I am not able to assign a static IPv6 address to my VLAN, but am able to request prefix delegation. Quite generously my ISP says sure you can have 16 /60's, but this obviously don't fix the spec of what I am trying to do. Simply put I want 6 of my /64 assigned as 1 too each VLAN. How do I tell pfSense to do this or am I just going about this all wrong?
This is how it looks (but I don't want 16 /60's):

The point of PD is for your isp to give your router a prefix so it can hand out addresses and route traffic. With a /60, you have 4 bits, which is 0x0-0xf of prefix id, 16 subnets.
Please post your wan, lan and dhcpv6 settings. No need to post all subnets, just one subnet.
-
The /60 prefix means you have been assigned a block of 2^68 addresses, comprised of 16 /64 blocks. You configure your router to use one or more of those /64 blocks to provided addresses to your local network(s). In pfSense, on the LAN interface tab, you can select which of the 16 to use in the IPv6 Prefix ID box. You do this for each interface, including VLANs that you have.

Screen captures seem okay. There are not multiple /60 prefixes. You are seeing the /64 after the 4 bit id is appended. I don't use VLAN, so have no comment on it. You might want to disable all except wan and lan interfaces to reduce clutter in the log while you sort this out.
Please post Services / DHCPv6 Server & RA / LAN / DHCPv6 Server and Services / DHCPv6 Server & RA / LAN /RA.
Also, take note of the time, then in interfaces / wan, click save then apply. After that, post the system and dhcp logs.
What client are you using? If windows, use ipconfig /release6 and ipconfig /renew6, then ipconfig /all to see status.
Also, run ipv6-test.com and test-ipv6.com. There should be firewall rules to pass icmp4 and icmp6 echo-request.

No, ifconfig doesn't lie or play tricks with the prefix lengths no matter how the addresses are configured. Those /60s are really assigned to the VLAN interfaces and that means there are multiple broadcast domains using the same /60 prefix which is 2605:6001:XXXX:5600:: . That configuration can not work, the prefixes on the VLAN interfaces should be /64 when inspected by ifconfig.

I was thinking that when I originally posted, then I edited the post after I looked at the number of bits. It looks like there is only one /60 but pfsense is just appending the additional 4 bits for each lan. I've never looked at ifconfig with more than one lan before. I don't have a multiple lan config running to look at.
Edit, just looked at ifconfig on my single lan system and it only shows the /64. Dunno what's happening in OP's system. I think he should disable the extra interfaces and make sure he can get it working properly with a single lan first.

This zero represents my 16 /64 networks, 0-9, a-fUnless I a misunderstanding how the delegation works (I read rfc3769), they are providing, but more than I am asking for, IMHO. With the Prefix ID
3.1. Number and Length of Delegated Prefixes
The prefix delegation mechanism should allow for delegation of
prefixes of lengths between /48 and /64, inclusively. Other lengths
should also be supported. The mechanism should allow for delegation
of more than one prefix to the customer.So my question is reduced to how should pfSense configure and route for the /64 nets. Something is funky here, I am not not certain where yet.
-
When you request a /60, the prefix id is 4 bits, 0x0 through 0xf. In the lan config, you chose a prefix id for the each lan. The prefix for the lan is isp prefix /60 + prefix id = /64. In the dhcpv6 server, you have always have 64 bits, :: through ::fff:fff:fff:fff. Just use ::1000 to ::2000. Try that and report back.

I shut down this virtual, moved it to the VLAN and modified the DHCPv6 range tp the requested ::1000 - ::2000 and got the last address in the scope as expected

Are the firewall allow lan to any rules enabled? I'm about ready to suggest that you reset to factory defaults and start over. Normally when I do an installation from scratch, I select the WAN and LAN settings for the tracked PD and it just works.

Can you post a screen capture of gateway and interface status?
Can you also post the output of ps aux | grep dhc?
It should look like this:

Good call on the new deployment, but I am still not yet working like I'd expect. The hard part is I am not "sure" what should be happening, haha. I am deploying IPv6 to learn about all of this and I've done a lot of reading but I'd expect that both DHCPv6 and RA are both pretty much automatic on pfSense.
For today I need to rip this out, so I can work. I am dropping back to only 1 VLAN with IPv6 and will see what I can sniff when I have some free time today.
-
I recommend making only the required changes to defaults to get it working, then have your way with it.
When I do a fresh installation, after the initial setup, all I have to change to get ipv6 working is to set the wan configuration, the lan configuration and dhcpv6. It literally takes a few minutes.
On the dashboard, enable interface and gateway status so you can confirm that the gateways are working.
WAN: ipv4: DHCP, ipv6: DHCP6. The DHCP6 client settings depend on your ISP. Try setting /60 and prefix hint.
LAN: ipv4: static, ipv6, tracking WAN.
dhcpv6: enable range ::1000 to ::2000.
It doesn't hurt to reboot at this stage, but interface / wan save, apply or status interface wan release, renew should accomplish the same thing.
That's all you should have to do to get dhcp and dhcp6 leases on your lan. If you set up unbound, you will see the same dhc* processes that I posted above.
If you're using a windows client, ipconfig /release, ipconfig /renew, ipconfig /release6, ipconfig /renew6 will result in leases. (Or disable and enable the adapter should do the same thing.)
If you want to verify everything with ipv6-test.com, also enable allow firewall rules in pfsense for icmp4 and icmp6 echo-request, as well as virtual machine monitoring ipv6 echo-request on the windows client.
Later, you may want to enable the setting wan / do not allow PD release. That will make it more likely that your prefix stays the same.

Hey, looks good. Glad you got it working. Since I'm not using vlans or have even played with them, hopefully someone else will jump in.
I appreciate the level-set to go back to a base image, I needed to remember I was troubleshooting and to follow the KISS principle.
I have the VLAN up now, just waiting until the end of my shift to move back to my switch. My understanding of VLANs and IPv6 is probably not what is should be, but I am reading rfc4554 https://tools.ietf.org/html/rfc4554 to sort that out. The introduction seems to indicate this should "just work" in the following
If such a site wishes to introduce IPv6, it may do so by deploying a
parallel IPv6 routing infrastructure (which is likely to be a
different platform to the site's main infrastructure equipment, i.e.,
one that supports IPv6 where the existing equipment does not), and
then using VLAN technology to "overlay" IPv6 links onto existing IPv4
links. This can be achieved without needing any changes to the IPv4
configuration. The VLANs don't need to differentiate between IPv4
and IPv6; the deployment is just dual-stack, as Ethernet is without
VLANs.The IPv4 default route to the VLAN is provided by one (IPv4) router,
while the IPv6 default route to the VLAN is provided by a different
(IPv6) router. The IPv6 router can provide native IPv6 connectivity
to the whole site with just a single physical interface, thanks to
VLAN tagging and trunking, as described below.The IPv6 connectivity to the enterprise may or may not enter the site
via the same physical link as the IPv4 traffic, and may be native or
tunneled from the external provider to the IPv6 routing equipment.I guess I'll have to see what I get. I need to move this link back over to the switched network first and test and make sure things remain the same for connectivity of IPv4 and IPv6 on LAN then move to my VLAN which supplies the tagging. I'd thought this would just work in ESX, but I'd need a pfsense interface per VLAN for that to be the case.
