As far as I understand it, these are equivalent.  In any case,
I also tried the 'official' RedHat way of creating an ifcfg-eth0:1
and doing ifup eth0:1.  Quagga still does the same thing.

In fact, it's actually worse than I initially thought.  Sometimes,
all the OSPF routes disappear and never come back when I 
bring up eth0:1 or do the ip addr add, but restarting
ospfd gets them back.  I'm not in a position to look at the
logs right now, but ospfd moans something about not being
able to find an ASBR for certain routes.

I'll post exact logs later.

Later,
