OK.  They are listed so:

$ ip addr show eth1 (some stuff x'ed out)
3: eth1: <BROADCAST,MULTICAST,UP> mtu 1600 qdisc pfifo_fast qlen 1000
    link/ether 00:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet xxx.xxx.136.50/29 brd xxx.xxx.136.55 scope global eth1
    inet xx.xxx.1.1/26 brd xx.xxx.1.63 scope global eth1:1
    inet xx.xxx.0.130/30 brd xx.xxx.0.131 scope global eth1:2
    inet6 xxxx::xxx:xxxx:xxxx:xxxx/64 scope link
       valid_lft forever preferred_lft forever 

And now that I look at "show interface" again on the zebra interface, I see
that all 3 IP addresses are listed on eth1, so my bad there.  So I removed
the config from zebra for eth1:1 and eth1:2.

However, that doesn't bring me much closer to getting OSPF and BGP working
on these two additional networks corresponding to eth1:1 and eth1:2...
(What does one call them if not a virtual interface or an alias now then?)

Thanks, Seb

There is no such thing as virtual interfaces or aliases in Linux for may
now. It was working this way on 2.2 (or 2.0?) kernels. Try to list your 
interfaces and addresses with `ip address list` and it will show you real 
interfaces - and probably the ones which quagga is seeing.
