Hi, I have network with RA server and I need to set up my Mikrotik box to accept and set ip address over RA packets. In linux and freebsd is it defaut behavior, but I have problem to set up this on Router OS.

I upgrade my RB532A to 5.0beta6 and still have problem, how to set up this. I need to set up my ether1.

Thank you for advice.

IPv6 address from RA is set only to hosts. Address on Router must be set manually.

Very bad information for me
What about in the future? Is any hope to have full ipv6 support in RouterOS?
This is simple think -

ISP (RA) - ether0 (configured by RA) - ether1 (configured as RA daemon with prefix routed by ISP) - home network
When ISP change prefix (on ether0), so I have to change ether0 address by hand

Anyway, thank you for you response.

This is not a Mikrotik limitation. Such behavior is defined in RFC. Until RFC is not changed, behavior will be as it is right now.

Hi, thank you for response, may I ask you, which section of which RFC do you mean?

Thank you

RFC4862 Section 1

The autoconfiguration process specified in this document applies only
to hosts and not routers. Since host autoconfiguration uses
information advertised by routers, routers will need to be configured
by some other means.

Oh, thank you very much. I was a little bit confused, because FreeBSD based routers (and some linux based) have RA accept enabled by default. This make sense in most cases (yes, ve confingure routers by hand, bgp, etc.), but not for home and end users with home routers. They (We ) get wire from ISP and if ISP make change, they have to change it by hand (i dubt about bgp for end user and DHCP6 isnt wide supported).

Chm, what about checkbox for decision - Yes, I want to use RA

RA is only for end users (hosts), for routers it is unusable because you still need address block for hosts behind a router and there is no NAT in IPv6 where you can hide private network behind one global IP address.

Ummm, yes, probably.....

So if we talk about end router (home user) lets try imagine following situation:

ISP RA server (give address to home router)
HOME router
home network

If ISP changes IP prefix, it has to change routa to new address. So home network is untouched, home router changes its address automatically over RA - no manual work for end user. Is it bad idea?

We talk about end user, of course.

Thank you

There is support for prefix delegation in DHCPv6 (RFC3633). And more info about CPE router requirements is in draft-ietf-v6ops-ipv6-cpe-router. Quite complex stuff compared to IPv4. On the other hand, with IPv4 it was just getting one address from DHCP and then NATing it, i.e. as simple as possible.

try imagone situation... have RB411 like bridge only, all interfaces bridged. and I need to get IPv6 adress fo it. It is a router or it is a host? will be RA usable in this case for me ?
