split-horizon solved the problem of routes coming back with a different
mask.... however, the /26 mask on all updates remains....
any ideas?

ok... so I configured it... and now it advertises all /24, /25 and /26
networks with a /26 mask :-( .....
Result: I get routes looping around: router 1 advertises a /24 route out to
router 2, router 2 send it back with a /27 mask and router 1 enters it in
its routing table as a more specific route than its local one..... This is
crazy!
I removed the secondaries and it works fine. I put them back, clear ip route
and here we go again.... this is ridiculous....
Any ideas?

well not according to my routers :-)
unless I'm doing something wrong......
{trying again)
well, u know something... you are both absolutely right....
I don't know why it didn't accept it before but it does now: I just tried it
again. (probably getting late for me :-)
I stand absolutely corrected!!!!! Thank you for insisting :-)
Now, back to the issue:
This is one solution that should work... though not very elegant. Any other
ideas? Something "cleaner"?

What do you mean it only accepts one? Using the secondary command will
allow as many secondary IP addys that the memory can handle according to
cisco.

It only accepts one :-)
I tried that already. The interface will only keep the last one you
enter.... :-(
(Besides, it would be an AWFUL waste of IP addresses.... Something that our
friend who needed more than a trillion address wouldn't appreciate :-)

Why not configure multiple secondary addresses?
