In my opinion you are much better off using VSWITCH's.   It is one layer
less in the path length and you don't have to have a host to perform
routing.   The vswitch also supports layer 2 routing rather than layer 3
(more efficient).

Guest Lan/VSwitch/VLAN






Hi All,

I know this is a broad question, but I am trying to understand some
things.

We currently are using CTC connections for our network access to our
Linux Instances running under VM.  We were told that CTC's were doing it
the hard way.  So I am trying to figure out what the other way is.

We have Z/VM 5.1 running on an IFL and an OSA-Express card.  What
should we be using instead of CTC's for network connection, VGuest,
VSwitch VLAN?  I'm confused as to what each actually does.

Any help would be appreciated.

Thanks
Gene
