         L3 networks types include:

         The FABNet networks are internal IP internets that span the
-        FABRIC testbed.  Adding a new L3 network to your FABRIC slice creates
-        an isolated network at a single site.  FABRIC issues each isolated
-        L3 network with an IP subnet (either IPv4 or IPv6) and a gateway used
-        to route traffic to the FABNet internet.
-
-        Like the public Internet, all FABNet networks can send traffic to all
-        other FABnet networks of the same type. In other words, FABNet networks
-        can be used to communicate between your slices and slices owned by
-        other users.
-
-        An exception will be raised if the set interfaces is not from a single
-        FABRIC site.  If you want to use L3 networks to connect slices that
-        are distributed across many site, you need to create a separate L3
-        network for each site.

-        It is important to note that by all nodes come with a default gateway
-        on a management network that use used to access your nodes (i.e. to
-        accept ssh connections).  To use an L3 dataplane network, you will need
-        to add routes to your nodes that selectively route traffic across the
-        new dataplane network. You must be careful to maintain the default
-        gateway settings if you want to be able to access the node using the
