I have the following network configuration:
# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 178.63.21.204 netmask ffffffc0 broadcast 178.63.21.255
ether 0:1b:21:5d:8e:5a
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252
index 1
inet6 ::1/128
# netstat -nr
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ---------- ---------
default 178.63.21.193 UG 1 3

Destination/Mask Gateway Flags Ref Use If
--------------------------- --------------------------- ----- --- ------- -----

When I do the following:
# ifconfig e1000g0:1 plumb
# ifconfig eth1000g0:1 178.63.21.249/26 broadcast + up
I loss my network connectivity. The IP "178.63.21.249" is a second IP address
from my hosting service that I should use. Why do I loss my network
connectivity at all? I need then to reboot the whole server to be able to
re-login at 178.63.21.204.
I have the same problem if I configure this second IP address in a zone. If I
start the zone I loss my network connectivity. I can't anymore ping the server.
My OS is:
# cat /etc/release
