Configuring a second interface to use the same IP stack:

First, check to	ensure that both devices can be	detected:


  ; ls '#l0'
  ; ls '#l1'


If the device cannot be	detected, you will see:


  ; ls '#l2'
  ls: #l2: no free devices


Next, bind the device to a new IP stack	 in  /net.alt,	then
use ipconfig to	add the	address:


  ; bind -b '#l1' /net.alt
  ; bind -b '#I1' /net.alt
  ; ip/ipconfig	-x /net.alt -g 198.51.100.1 ether /net.alt/ether1 add 198.51.100.2 255.255.255.0


Replace	 198.51.100.1  with  your  actual  default  gateway,
198.51.100.2 with your public IP address, 255.255.255.0	with
your subnet mask.

If configured properly,	/net.alt/iproute should	show  routes
similar	to these:


  ; cat	/net.alt/iproute
  0.0.0.0	  /96  198.51.100.1 4	 none	0 198.51.100.0 /120
  0.0.0.0	  /96  198.51.100.1 4	 none	0 198.51.100.2 /128


From another machine, ping the IP address 198.51.100.2:


  another% ip/ping 198.51.100.2


Then, on the machine with 198.51.100.2,	verify	with  snoopy
that packets are received on the correct interface with	cor-
rect ethernet and correct IP address:
