RouterOS 7.1beta6 - GRE Tunnel does not work with non Mikrotik devices (fix)

Mitglied: colinardo
Small advice for all users trying to create a simple GRE Tunnel to a non Mikotik device under the current beta version.

If the tunnel does not come up, disable the keepalive setting for the tunnel interface. This is a proprietary Mikrotik implementation which does not work with other common GRE tunnel implementations.

Hope this helps.

Thanks for this feedback !
Added this advice to the GRE_Tunnel_Tutorial as well.
Btw. Cisco supports a GRE keepalive too but did NOT recommend to use it, cause of some major protocol drawbacks:
