While running some pings in my lab across my compound frame-relay switches,
I noticed that my ping times were very slow. This was due to the fact that
I was going through a 38.4K connection (aux to aux). When I increased the
byte count of my pings to 1500, 7 out of every 10 failed. I want to run Qos
(CAR, FRTS, etc...) and thought it would be better to do it across a faster
connection.
I tried to increase the speed of aux port to improve response times, but the
max is 38400. So instead of tunneling across the async interfaces, I
thought why not tunnel across the Ethernets of both routers. I connected
the routers via a crossover cable, changed the tunnel config to point to the
E0's and it works beautifully. 10 meg as opposed to 38.4K.
I'm sure I'm not the first to think of this, but it's just an FYI to whoever
is running this setup and experiencing the same problem I was.
HTH,
Danny

I used 12.2(1d) enterprise and got it to work.
I see one strange thing after looking closely at the configs. The way the
frame-relay routes are configured doesn't make too much sense to me. I
configured it and it is working, but I don't fully understand why the routes
are configured the way they are. It almost seems incorrect. Take a look.

Hi all,
Danny, I have upgraded my router to 12.2(23) and it works:
(config-if)#frame-relay route 211 interface ?
Serial Serial
Tunnel Tunnel interface
Regards,
Mounir

Then this is pretty weird. I basically copy pasted what was on the
internetwork expert site. Perhaps something is missing in their example?
I'll look online for more info.
Thanks, Marvin
Danny

Your IOS just has to support frame-relay switching and
tunnels. I believe the first example I saw for this
was with 11.3 IOS. You can also do it over an
ethernet/token port instead of AUX.
