Hi Dietmar,
I'll work next week on /etc/pve/networks.cfg,
I have take time to polish the configs file, I'll would to have some feedback
before coding.
1) add transportzone in /etc/network/interface.
only on physical interfaces (eth/bond), not tagged interfaces.
This is only an hint, not used by ifupdown.
1 transportzone can be set only on 1 interface.
/etc/network/interfaces
-----------------------
auto eth|bond
transportzone zone1
2) add a new /etc/pve/networks.cfg configuration, with 2 main sections
/etc/pve/networks.cfg
a) the transportzones (with plugins),
where we can define if a transport zone is a vlan, vxlan,... with differents
attributes specific to the plugin.
some examples:
#transportzones
vlan: zone1
vlan-aware 1|0 (qinq)
allowedid: 1 - 4096
vxlanmulticast: zone2
vxlan-svcnodeip 225.20.1.1
allowedid: 1-16millions
vxlanunicast: zone3
vxlan_remoteip proxmoxip1,proxmoxip2,proxmoxip3,....
allowedid: 1-16millions
vxlanfrr: zone4
vrf:
l3vni: id
l3vnihwaddres: macaddress
allowedid: 1-16millions
b) the networks/bridge/switchs,
where the attributes are common.
(basicaly, this is a bridge config with vlan/vxlan id)
#network
switch : mynetwork1
transportzone zone1
networkid: (vlan/vxlan-id)
switch: mynetwork2
transportzone zone4
networkid: (vlan/vxlan-id)
address: cidr
hwaddress: 44:39:39:FF:40:10
3)
After that, I think we need a new daemon, to generate /etc/network/interfaces
locally
on each node, do ifupdown2 reload on change,.... maybe do we need to manage
that on a separate config ? /etc/network/interfaces.d/networks.cfg ?
(or maybe reuse pvestatd ?)
I'm not sure for the generate interfaces name, as we have 16characters limit:
auto vxlanmynetwork1
auto vmbrmynetwork1
maybe use an id by switch, to be able to do something like
/etc/pve/networks.cfg
switch : vnet1
name mynetwork1
/etc/network/interfaces
auto vxlanvnet1
auto vmbrvnet1
(can't use the vxlanid in name, as we have 16millions characters)
What do you think about this ?
