Now that my BGP announced 44.x range is up and running, I'd like to be
able to make it transparently accessible for tunneled networks. I just
need to double check a few things.
First, I know I'd need to run ampr-ripd on the box. I also have non-44
net addresses to use as the ipip encap endpoint. What else do I need to
do? Do I need to advertise the subnet as "tunneled" in addition to
direct in the portal? Anything else?
Reason for this is I'm likely to be running services other than Echolink
proxies, which may require peer-peer connectivity. Currently, 44.x
tunneled addresses connecting to the system would go via their local
router, which most likely involves NAT.
And on a similar note, is there a way to exclude other directly
connected subnets capable of IPIP tunneling from using a tunnel? (since
that's obviously not required!)

I advertise my /23 via 2 providers.
We then use our internal routers to break them down into subnets i require.

That
doesn't answer my question at all, seems to answer an entirely
different question, which I'm not sure is relevant.

With your other questions please contact me off list and I will be send you my config
In short nothing changed greatly in our apps.
I run tnos, aprs. Mmdvm etc on 44net as well I can duplicate the network via eoip to our
colo

If you've got it accessible to the internet at large via BGP, it'll also be
accessible from other 44 networks. Without the tunnel mesh, traffic will be
routed through amprgw at UCSD. There used to be a configuration issue that
prohibited this, but it was fixed a few years ago.
You can of course still configure the tunnel mesh if you desire. The
primary benefit of this is reduced latency to gateways not near UCSD.

This should answer your questions:

The way we do this is by importing the 44 networks learned via BGP into our
IGP and prioritizing those over routes learned via ampr-ripd. The route
filter looks something like this on Mikrotik:
/routing filter add action=accept chain=AMPR prefix=44.0.0.0/8
prefix-length=8-32
Now our route table has routes from both BGP and ampr-ripd, with lower
distance on the BGP routes. How you accomplish this will depend on your
implementation, but I hope this gives you an idea.

Depends on the routing setup at
the remote end, and for various reasons,
that's not a desirable path

Which
includes anything here! Also on today's Internet, vastly
increased available bandwidth, because of the more optimal routing.
