Sadly, I thought of the too after I sent my first message. No change. Here
is my current "ip addr show" for eth0:
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state
UP qlen 1000
link/ether 00:50:56:XX:XX:XX brd ff:ff:ff:ff:ff:ff
inet 192.168.200.111/24 brd 192.168.200.255 scope global eth0
inet 172.35.24.54/22 brd 172.35.27.255 scope global eth0:2
inet 10.111.111.1/24 brd 10.111.111.255 scope global eth0
inet 192.168.200.54/24 scope global secondary eth0:0
inet6 fd00:200:0:1::1/64 scope global
valid_lft forever preferred_lft forever
inet6 fe80::250:56ff:fe8f:XXXX/64 scope link
valid_lft forever preferred_lft forever
Interestingly, ifconfig does NOT show 10.111.111.1. (It is there and
working, I can ping that address.) I wonder if the ISC DHCP server does
not recognize addresses added by iproute2?
