A I understand it I can use the usesrc option of the ifconfig command and a vni
interface to configure the default source address used for a network interface
with multiple IP addresses in OpenSolaris/Solaris 10.
And in my understanding to use this feature I must configure the desired IP
address twice - once for the "physical interface" (bge0, bge0:1 or something
like this) and once for the vni interface.
e.g.
(bash):[EMAIL PROTECTED]:/root # ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1
inet 127.0.0.1 netmask ff000000
vni0: flags=20010100c0<RUNNING,NOARP,NOXMIT,IPv4,VIRTUAL> mtu 0 index 2
inet 192.168.178.202 netmask ffffff00
bge0: flags=1004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4> mtu 1500 index 3
inet 192.168.178.101 netmask ffffff00 broadcast 192.168.178.255
ether 0:c0:9f:f4:6a:3c
bge0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 192.168.178.202 netmask ffffff00 broadcast 192.168.178.255
bge0:2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 192.168.178.245 netmask ffffff00 broadcast 192.168.178.255
In this example I want to use the IP address 192.168.178.202 as default source
address for outbound IP traffic on the bge0 interface.
Now a
ifconfig bge0 usesrc vni0
should do it.
It this a correct usage of this feature?
Another question:
If I use the same network adapter for other networks and for zones - which
source IP address is then used for outbound traffic from inside the zone or if
I connect to other networks via this network adapter?
e.g. which source IP address is used after issuing
ifconfig bge0 usesrc vni0:1
in this example?
(bash):[EMAIL PROTECTED]:/root # ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1
inet 127.0.0.1 netmask ff000000
lo0:1: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1

inet 127.0.0.1 netmask ff000000
lo0:2: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1
zone testzone004
inet 127.0.0.1 netmask ff000000
vni0: flags=20010100c1<UP,RUNNING,NOARP,NOXMIT,IPv4,VIRTUAL> mtu 0 index 2
inet 192.168.199.1 netmask ffffff00
vni0:1: flags=20010100c0<RUNNING,NOARP,NOXMIT,IPv4,VIRTUAL> mtu 0 index 2
