I've actually done something like this in a lab. I wrote about it on the
list a few months back. I am e-mailing you the configs in a separate
message. ( too big for Paul to let through to the list ) but a relevant
excerpt follows:
Router A
interface Tunnel0
ip address 172.17.1.1 255.255.0.0
tunnel source Serial0
tunnel destination 192.168.101.1
Router B
interface Tunnel0
ip address 172.17.2.2 255.255.0.0
tunnel source Serial1
tunnel destination 192.168.102.1
the tunnel destinations on either router are the outside ( internet, if you
will ) IP addresses of the serial interfaces. These are on entirely
different networks, as would likely be the case in a real world situation
or why would you need the tunnel the first place? Duh! ) The tunnel itself
does have to be on the same subnet, as you can see from both router tunnel
interface addresses.
You will see when you get the configs.

Subject: EIGRP over OSPF and BGP
Hi, all!
By the way, thanks to all who wrote me about where to find a cabinet... got
some good leads out of it!
Y'all know how I love to post messages addressing weird situation and
problems? Usually, it intrigues Chuck L., causing hiim to suspend his
studies while he investigates what the heck I wrote about;)
Anyways, I got another one:
Given:
EIGRP 1 RTRA OSPF RTB BGP RTR C OSPF RTRD EIGRP1
I want RTRD and RTRA to become EIGRP peers and do the exchange routing
update thing. Granted, they are not directly connected, and do not share a
common subnet. If I set up a GRE tunnel between D and A, the picture then
becomes:
EIGRP1 RTRA <---tunnel---> RTRD EIGRP1
The tunnel becomes the common network, and therefore, EIGRP should be able
to work. Only thing I am not sure about is the source interfaces for this
tunnel will be different at each end (that is, each source interface will be
in a different subnet). I don't have my rack online to test this out, so
would appreciate any comments.
Thoughts, anyone?
