Hello,
while analyzing the routing table on my Mikrotik router, I noticed
that there are 2 gateways for 44.136.0.0/21:
114.198.116.219
203.5.58.162
The encap file has both as well:
route addprivate 44.136/21 encap 203.5.58.162
route addprivate 44.136/21 encap 114.198.116.219
I have tried to create 2 routes for some of my networks via the
portal, but the portal complains with the words "The network overlaps
an existing entry".
I'm now interested to know, if these 2 routes are intended to
co-exist? If yes, how can one create those entries via the portal.
If no, which one is correct and why are there 2 entries?

Hi Marc,
No, there should not be two entries for one route and the portal should not allow this to
happen, so I will look into how it occurred and amend the code as necessary.
Thanks,
Chris

are these 2 entries for a single route or 2 separate routes to a single
destination? It seems to me they are actually separate redundant routes to
the same /21. should redundant routes not be allowed? It would seem quite
the reverse that redundancy being useful and importaint these ought to be
allowed to stand so long as they are valid routes to the specified /21.

No they shouldn't both be allowed. There isn't a way to dynamically choose the
route based on whether one or the other connection is up. Packets sent to the
down route are simply lost.

No, because of a fundamental difference. The SMTP protocol is a
higher-level one which uses TCP connections which of course have a status
of succeeded or not, so if a connection specified by an MX record does
not succeed (is refused, etc) the mailer can try an alternate.
IP is much lower level and has no such status: packets are not
acknowledged at the IP level so there may be no notification that a packet
has not reached its destination. There is no way at the IP level to
tell that a particular route isn't working and to therefore try another.
There are proposed mechanisms to allow a choice of routes (RSPF, OSPF,
etc), but none of them have been implemented on AMPRNet and the existing
encap scheme doesn't allow for them (yet).

Is there a workaround to this, that would allow a remote site to
access net44 directly via it's Internet connection, but fall back on a
Microwave link if its Internet failed?
The only solution that I've been able to think of that would work in a
timely manner is using an OpenVPN server to handle all my net44
routing. This allows me to use OpenVPN's routing mechanisms to create
more advanced networks, but requires a colo machine with costs me
about $15 a month.
So far I've been able to get net44 routed into my colo machine
(44.4.36.1) and connect up my iPhone and MacBook Pro to that subnet as
VPN clients. Routing between those three machines and out to the rest
of net44 seems to be working (mostly). I'm a bit stalled out right
now until I get my microwave gear in the mail.
Any cheaper solutions out there??

As far as I'm aware, only through BGP. If you have access to a core cisco router, you
can do something like
sh ip bgp 1.2.3.4
and see the multiple routes for an address (if they have some).

You can also use a BGP LookingGlass server via the web and there are
MANY of them out there:

I personally find Hurricane Electric's UI the easiest to use, it
supports IPv6, etc.

ok, multiple static routes to the same place I can see why not. We do have
dynamic routing available to us though via RIP. Would RIP or another
routing protocol not handle this in the case of the route being unreliable
and drop that route? Why must routes be persistent rather than dynamic?
In a larger sense and I realize we're not there yet it would seem that
rather than having to know the routes to all other 44net hosts from boot it
would be much easier to have each area (for instance each /16 or maybe in
some cases each /24) to have a designated router (say at .1) or possibly
use multicast to discover one's local router. thus the initial config is
simplified as it has a single route to the 44net gateway for it's area from
which it may discover via dynamic routing other routes. no more need to
manually distribute and update a routing table. This seems to be something
to work towards.
