[pve-devel] [PATCH pve-docs 0/1] vxlan l3 routing

>>Another way, could be make somekind of template on each local host. (as we only need to duplicate them for each vlan/vxlan). 

for vlan, 
---------
keep using an vmbr a template

auto vmbr0
iface vmbr0 inet manual
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0



Maybe it could be possible to reuse ifupdown2 native template too ?

%for v in [1,2]:
  auto vmbr0v${v}
  iface vmbr0v${v}
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

%endfor

not sure if we could define the vlan/vxlan id in a list/variable somewhere, an simply reuse them.


/etc/pve/interfaces.vlanlist 

$mylist=[1,2]

then in
/etc/network/interfaces

include /etc/pve/interfaces.vlanlist 

%for v in $mylist:
  auto vmbr0v${v}
  iface vmbr0v${v}
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0
%endfor


or for vxlan


%for v in $mylist:

auto vxlan${v}
iface vxlan${v} inet manual
      vxlan-local-tunnelip 192.168.0.1
      bridge-learning off
      bridge-arp-nd-suppress on
      bridge-unicast-flood off
      bridge-multicast-flood off

auto vmbrvx${v}
iface vmbrvx${v}
        bridge-ports vxlan${v}
        bridge-stp off
        bridge-fd 0

%endfor

Another way, could be make somekind of template on each local host. (as we only need to duplicate them for each vlan/vxlan). 

I need to check, they have a concept of "transport zone", seem to be an abstraction between distributed switch and physical host.(and some kind of vrf/vlan isolation)

IMHO this looks like a hack - I wonder how VMware associates the global net to 
local devices on the host?

Yes. Would be great if you work on that.
