Hello All. I hope you are doing fine. Just a question regards Router Mikrotik Rb2011il-rm. Do it support IPv6? I was looking this specification here: https://mikrotik.com/product/RB2011iL-RM
But I couldn’t find it.
And by the way, what I have to do is a LAN (intranet) with IPv6 support and NAT to IPv4 (public IP gives by ISP).
IPv6 is a software feature, not a hardware feature.
RouterOS does support it, so any router running RouterOS will have it too.
Start with this: https://wiki.mikrotik.com/wiki/Manual:IPv6
You will need to enable IPv6 package first.
Thanks for the quick response. But what happens with Ethernet’s MTU. Must it increase? because now the IP headers increase from 8 bytes to 32 bytes so the payload size decrease if the MTU is 15000. Must I increase it? and more it will increase if I want to use GRE and IPsec
The IPv6 MTU is also 1500. This just means that the max payload per packet is reduced.
The IPv4 header is 20 bytes, and the IPv6 header is 40 bytes, so the difference is 20 bytes of payload reduction per packet.
As for the IPv6 support in RouterOS, there have been a few threads recently about the bare bones nature of ROS’s IPv6 support.
In my personal view, the state of the union with IPv6 support in RouterOS is as follows:
Does it work? Yep.
Does it work well? Sure.
Does it have feature parity with the IPv4 feature set? Nowhere near it.
Does it have many new features related to IPv6 that aren’t relevant in IPv4? A few basic ones that are required for the thing to work at all, but don’t expect anything fancy.
Does Mikrotik appear to have a strong stance about IPv6? Not really. They support it, and they do actively fix bugs in IPv6 but there’s been nothing I’ve seen at MUMs, in the newsletters, or in their official participation on the forums that leads me to believe that IPv6 is any kind of a priority.
Well summarized Zerobyte. MikroTik users, continue to post questions about IPv6 support. The best way to ensure MikroTik begins to become more forward thinking about IPv6 is to continue to show them that a growing segment of their user base are interested in or in need of IPv6 features.
