That's normal. ifconfig knows nothing about addresses added using "ip
addr add". You can make it visible to ifconfig by adding label:

ip addr add dev eth1 ... label eth1:my-label

Just stop using ifconfig/route and keep using the ip command.
ifconfig/route have been deprecated for a decade now and I know old
habits die hard but at some point you just have to move on otherwise you
might end up like those admins who stopped learning in the 80s and now
haunt discussion forums mostly contributing snark and negativity because
they've come to hate their jobs.

I guess I have to say "never mind!" I don't know what the problem was
yesterday, but it loads just fine today, even when the named config and the
virtual ip don't match! But for your edamacation, ifconfig does NOT show the
address although ip addr does:
