First, gifs must be supported in your kernel (enable "pseudo-device
gif" in your kernel config).
src_addr is the address of your NIC's interface while dest_addr is the
remote side or the other end of the tunnel IP address. For example, if pc1
is one end of your tunnel and pc2 is the other end, then:
if in pc1, you have:
xl0: 1.1.1.1
gif0:
if in pc2, you have:
de0: 1.1.2.1
gif0:
on pc1, do the following:
pc1# ifconfig gif0 1.1.1.1 1.1.2.1
on pc2, do the following:
pc2# ifconfig gif0 1.1.2.1 1.1.1.1
You can also man gifconfig .
I haven't tried using gif interfaces for IP-in-IP tunneling. I've
only used them for IPv6 in IPv4 tunneling, but you can test it.
Also, I'm not really knowledgeable in lvs. I'm still in the reading stage
so I can't really comment on how you can make gifs work with lvs.
HTH,
