Hello all,
If you may have noticed, there is a recent IPIP tunnel with a 44net gateway (which you may have seen flapping on your Mikrotik routers - 44.130.120.0/24 via 44.130.120.65).
This is a experimental setup to allow tunneling via BGP announced 44net gateways, with no real hosts there yet.
Ampr-ripd newer than 1.13 will ignore this RIP broadcast (an update will be available soon).
Our first step to make it run on Mikrotik routers (this will stop the route flapping):
Announcing the Mikrotik RIPv2 AMPR Gateway Setup Script 3.0 (21.Jan.2017) - Added support for tunnels with BGP announced 44net endpoints
If you already use v.2.x, only update ampr_gw and from the archive file and add manually the new parameter "AmprDefaultGw" to your config file (see the example file in the archive). "AmprDefaultGw" can be set to your gateway WAN interface name or the correct gateway IP for your router.

Marius,
If it's helpful for your test data, we successfully used 44.24.221.1 as a gateway for 44.24.240.0/20 about three years ago. This worked fine for encap users that did not have an extra 44.0.0.0/8 route in their table (for some reason this configuration is popular, despite breaking things). We used this gateway until it was blocked in a portal update.
Of course this is different than your test because our gateway was not contained within the advertised network.

Hi Marius...added new script and still flaps here.

Hi Leon,
You are missing the double colon in front of "global":
:global AmprDefaultGw "24.115.112.147" ;

Leon,
Do you have 2 routes in your routing table?
44.130.120.0/24 ampr-44.130.120.65 reachable
44.130.120.65 <Your Interface> reachable

Ok. I know what's wrong.
The route is created only at tunnel creation.
So you need to delete the ampr-44.130.120.65 tunnel interface.
On first run it will be recreated and it will be ok.
Also there probably will be an invalid route to 44.130.120.0/24 which has to be cleared by hand.

Hi Marius,
Thanks for the update. I've experienced the same flapping of
ampr-44.130.120.6. Deleting the tunnel and associated route fixed it for me.
