Since kernel 2.6.28 linux supports Ethernet over GRE encapsulation (http://git.kernel.org/?p=linux/kernel/g ... 22e2ec7a6b).
This new gretap interface can be used in bridges and we can create ethernet bridges between Linux and RouterOS.
Because RouterOS is Linux based, this feature is probably already in RouterOS kernel, so it should be very easy for Mikrotik developers to implement it and it will be very helpfull to make ethernet bridges between Linux and RouterOS.

No, gretap is different. Currently implemented mikrotik GRE interface can't be bridged and EoIP is mikrotik proprietary protocol.

ok so you just need to get more MikroTiks and work with EoIP

Year has passed, we have rc11 of RouterOS 6, but this feature is still not available. And it just need to make interface in winbox/webfig/command line because it is already in kernel.

Did you email support to ask for this feature? Was it promised that it will be made? Forum is not always monitored by staff. This is the first time I see this topic.

Yes, I have wrote to support...

Anyway, what was this change?

*) gre - support all protocol encapsulation, not just ip and ipv6;

Hi Normis,

I hit a request from a client for such a feature as well. It seems gretap does not exist as an interface in Mikrotik.

Could this be added as a feature request?

Thanks,

Matthew.
