Hello. Is there any probel for a few days with yo2loj script? For a few
days I receive such a return in the logs of the mikrotik
"Jun / 06/2017 13:21:00 script, error AMPR: To few RIP entries available"

Jacek,
Check your routing table. There probably is a route to 44.0.0.1 & 44.0.0.2 in your
routing table pointing towards IPIP interfaces. Delete those routes and interfaces and
insert 44.0.0.1 & 44.0.0.2 in the filters for RIP with action reject or ignore.
That should fix everything and your RIP table will be populated again after 5 min orso and
you should be golden.
If you need the exact commands for the RIP filters, let me know and I'll forward them
once I get home tonight.

I had same problem...make sure the tunnel to UCSD has the correct
endpoint that should fix it.
I also created a address list with 44.0.0.1 and 44.0.0.2 in it and used
that as the source instead of 44.0.0.1 in the firewall filter as Ruben
suggests.

Can someone explain exactly how the 44.0.0.2/32 route is causing an
issue on the tiks?
Because that route could have been removed Monday anyway, as it would no
longer be needed if the migration was completed.
Did all services and routing move to New_AMPRGW yesterday?

Lynwood,
If it gets in the RIP table, the tik script will autoadd an IPIP tunnel for it towards the
new gateway (and 44.0.0.1 to the old gw)
This renders all future RIP broadcasts from 44.0.0.2 & 44.0.0.1 non functional. From
my firewall logs where I accept and log RIP, it shows the packets from the gateways but no
RIP broadcasts untill I remove those tunnels and routes

Ruben,
I'm trying to understand how tunneling works on various OSes. Many thanks.
OK, this issue could only be solved at migration. Similar to the Cisco,
your devices use multiple tunnels; apparently linked to the subnets
routed to them. I understand standard RIPv2 considers where the
announcement was received to be it's ENCAP Gateway. This needs to be
placed in the Wiki too. *This an anomaly due to the workaround on Mikrotik.*

That's about it for the IPIP tunnel and route towards it. There is also a dynamic
route for those subnets, but those get advertised by RIP as you well know.
But I omitted that part of the config as the script will go through all RIP routes and
create a tunnel for each RIP route and a static route towards that IPIP tunnel.

Lynwood,
The philosophy about that script is quite simple:
First, there is an isolated interface (usually called uscd-gw and the
isolated virtual space is called VRF in mikrotik language) which has the
gateway ip with netmask /8 (very important) which will receive RIP and
is the base IPIP tunnel to 169.228.34.84. This VRF has a route tag, i
use 44rip for it, and will place all received RIP routes in the 44rip
routing table (this has no effect on the actual routing).
The script parses these dynamic RIP routes and does 4 things:
- creates an IPIP interface for each gateway, one endpoint being the
local IP, the other being public gateway address of the mesh tunnel.
Interfaces are called ampr-<gateway_ip> (except for 44.0.0.1 which gets
dropped by a RIP filter - we already have that tunnel from the beginning).
- creates a static route via the systems default gateway if the endpoint
is in the 44net space, thus serves a BGP routed subnet.
- creates a static route in the main routing table for the serviced
subnet via the proper IPIP tunnel
- adds the interface to a interface list so that can be used for
firewalling purposes (not very important, but useful)
Of course, it checks if gateways and subnets get added or get deleted,
and adds/removes the appropriate entries for them.
Additional to this, the user has to ensure the following:
- provide a 88.0.0.0/8 route for 44net addresses which do not fit any
tunnel (BGP announced without tunnel interfacing). This could be either
via the ucsd-gw tunnel, or via the default ISP gateway with NAT .
- If one needs access from the internet, incoming connections via
ucsd-gw need to get a connection mark and the replies a routing mark, so
they can be routed back to the ucsd-gw tunnel. For this, for this
routing mark, a default route has to be set up via 169.228.34.84.
I hope this helps to understand the inner working of the Tick script.

It is simple. When the move started, I published a workaround for using
both gateways by creating an additional gw interface and apply some
connection/packet marks on it, so that outgoing 44 to internet traffic
would go via tunnel.
Now this new route appeared and created a tunnel with the same endpoint
parameters which took precedence over the old one, being newer.
So incoming traffic via the old gateway never got its connection/packet
marks and responses never got out via tunnel (old or new, it doesn't
matter).
