 Infix is a Linux Network Operating System (NOS) based on [Buildroot][1],

 platforms, simplify long-term maintenance, and provide made-easy

+The CLI configure context is automatically generated from the loaded
+YANG models and their corresponding [sysrepo][2] plugins.  The following
+is brief example of how to set the IP address of an interface:

+
+ - [ietf-system][]:
+   - [infix-system][]: MotD (Message of the Day) augment
+   - [infix-system][]: user login shell augment, default: `/bin/false`
+   - [infix-system-software][]: system-state/software augment for
+     remotely querying firmware version information
+   - [infix-system-software][]: firmware upgrade with `install-bundle` RPC
+   - [infix-system][]: timezone-name deviation, replaced with IANA timezones
+   - [infix-system][]: username deviation, clarifying Linux restrictions
+   - [infix-system][]: deviations for unsupported features, e.g. RADIUS
+ - [ietf-interfaces][]:
+   - [infix-interfaces][]: deviation for `if:phys-address` to allow read-write
+   - [ietf-ip][]: augmented with IPv4LL similar to standardized IPv6LL
+   - [infix-ip][]: deviations (`not-supported`) added for IPv4 and IPv6:
+     - `/if:interfaces/if:interface/ip:ipv4/ip:address/ip:subnet/ip:netmask`
+	 - `/if:interfaces/if:interface/ip:ipv6/ip:address/ip:status`
+	 - `/if:interfaces/if:interface/ip:ipv4/ip:mtu`

+	 - `/if:interfaces/if:interface/ip:ipv4/ip:neighbor`
+     - `/if:interfaces/if:interface/ip:ipv6/ip:neighbor`
+   - [ietf-if-vlan-encapsulation][]: Linux VLAN interfaces, e.g. `eth0.10`
+   - [infix-if-bridge][]: Linux bridge interfaces with native VLAN support
+   - [infix-if-veth][]: Linux VETH pairs
+   - [infix-if-type][]: deviation for interface types, limiting number
+     to supported types only.  New identities are derived from default
+     IANA interface types, ensuring compatibility with other standard
+     models, e.g., `ieee802-ethernet-interface.yang`
+ - Configurable services:
+   - [ieee802-dot1ab-lldp][]: stripped down to an `enabled` setting
+   - [infix-services][]: support for enabling mDNS and SSDP discovery

+### Changes
+
+- The following new NETCONF interface operational status have been added:
+  - admin-status
+  - IP address origin (dhcp, static, link-layer, random, other)
+  - bridge
+  - parent-interface
+  - basic statistics (`in_octets`, `out_octets`)
+- Support for custom interface `phys-address` (MAC address)
+- The CLI admin-exec command `show interfaces` now fully uses NETCONF
+  operational data to display both available interfaces and all of their
+  IP addresses.  Displaying an individual interface will show more info.
+- The CLI admin-exec command `password encrypt` now default to SHA512
+
+### Fixes
+
+- Fix #136: IPv6 autoconf `create-global-addresses true` does not bite
+- Fix #138: Not possible to have static IP and DHCP at the same time
+- Minor fixes and updates to documentation (faulty links, references)
+- The `sync-fork.yml` workflow has finally been fixed.

+| lag[^1]  | infix-if-lag      | Bonds multiple interfaces into one, creating a link aggregate |
+| lo       | ietf-interfaces   | Software loopback interface                                   |
+| eth      | ietf-interfaces   | Physical Ethernet device/port                                 |
+| veth     | infix-if-veth     | Virtual Ethernet pair, typically one end is in a container    |
+
+## Data Plane
+
+The blocks you ctose, and how you connect them, defines your data plane.  Here we see an example of how to bridge a virtual port with a physical LAN.
+
+![Example of a 4-port switch with a link aggregate and a VETH pair to a container](img/dataplane.svg)
+
+Depending on the (optional) VLAN filtering of the bridge, the container may have full or limited connectivity with outside ports, as well as the internal CPU.
+
+In fact the virtual port connected to the bridge can be member of several VLANs, with each VLAN being an interface with an IP address inside the container.
+
+Thanks to Linux, and technologies like switchdev, that allow you to split a switching fabric into unique (isolated) ports, the full separation and virtualization of all Ethernet layer properties are possible to share with a container.  Meaning, all the building blocks used on the left hand side can also be used freely on the right hand side as well.
+
+### Bridging
+
+This is the most central part of the system.  A bridge is a switch, and a switch is a bridge.  In Linux, setting up a bridge with ports connected to physical switch fabric, means you manage the actual switch fabric!
+
+In Infix ports are by default not switch ports, unless the customer specific factory config sets it up this way.  To enable switching between ports you create a bridge and then add ports to that bridge. That's it.
+
+```
+admin@example:/> configure
+admin@example:/config/> edit interfaces interface br0
+admin@example:/config/interfaces/interface/br0/> up
+admin@example:/config/interfaces/> set interface eth0 bridge-port bridge br0
+admin@example:/config/interfaces/> set interface eth1 bridge-port bridge br0
+admin@example:/config/interfaces/> leave
+```
+
+Here we add two ports to bridge `br0`: `eth0` and `eth1`. 
+
+> **Note:** Infix has many built-in helpers controlled by convention. E.g., if you name your bridge `brN`, where `N` is a number, Infix will set the interface type automatically for you, and unlock all bridge features for you.
+
+#### VLAN Filtering Bridge
+
+By default bridges in Linux do not filter based on VLAN tags.   It can be enabled in Infix when creating a bridge by adding a port to a VLAN as a tagged or untagged member:
+
+```
+admin@example:/config/> edit interfaces interface br0 
+admin@example:/config/interfaces/interface/br0/> up
+admin@example:/config/interfaces/> set interface eth0 bridge-port bridge br0
+admin@example:/config/interfaces/> set interface eth1 bridge-port bridge br0
+admin@example:/config/interfaces/> edit interface br0
+admin@example:/config/interfaces/interface/br0/> set bridge vlans vlan 10 untagged eth0
+admin@example:/config/interfaces/interface/br0/> set bridge vlans vlan 20 untagged eth1
+```
+
+This sets `eth0` as an untagged member of VLAN 10 and `eth1` as an
+untagged member of VLAN 20.  Switching between these ports is thus
+prohibited.
+
+### VLAN Interfaces
+
+Creating a VLAN can be done in many ways. This section assumes VLAN interfaces created atop another Linux interface.  E.g., the VLAN interfaces created on top of the bridge in the picture above.
+
+A VLAN interface is basically a filtering abstraction. When you run `tcpdump` on a VLAN interface you will only see the frames matching the VLAN ID of the interface, compared to *all* the VLAN IDs if you run `tcpdump` on the parent interface.
+
+```
+admin@example:/> configure 
+admin@example:/config/> edit interfaces interface eth0.20
+admin@example:/config/interfaces/interface/eth0.20/> set encapsulation dot1q-vlan outer-tag tag-type c-vlan vlan-id 20
+admin@example:/config/interfaces/interface/eth0.20/> set parent-interface eth0
+admin@example:/config/interfaces/interface/eth0.20/> leave
+```
+
+> **Note:** If you name your VLAN interface `foo0.N`, where `N` is a number, Infix will set the interface type automatically for you.
+
+## Management Plane
+
+This section details IP Addresses And Other Per-Interface IP settings.
+
+Infix support several network interface types, each can be assigned one or more IP addresses, both IPv4 and IPv6 are supported.
+
+![IP on top of network interface examples](img/ip-iface-examples.svg)
+
+### IPv4 Address Assignment
+
+Multiple address assignment methods are available:
+
+| **Type**   | **Yang Model**    | **Description**                                                |
+|:---------- |:----------------- |:-------------------------------------------------------------- |
+| static     | ietf-ip           | Static assignment of IPv4 address, e.g., *10.0.1.1/24*         |
+| link-local | infix-ip          | Auto-assignment of IPv4 address in 169.254.x.x/16 range        |
+| dhcp       | infix-dhcp-client | Assignment of IPv4 address by DHCP server, e.g., *10.0.1.1/24* |
+
+DHCP address method is only available for *LAN* interfaces (ethernet, virtual ethernet (veth), bridge, etc.)
+
+### IPv6 Address Assignment
+
+Multiple address assignment methods are available:
+
+| **Type**         | **Yang Model** | **Description**                                                                                                                                   |
+|:---------------- |:-------------- |:------------------------------------------------------------------------------------------------------------------------------------------------- |
+| static           | ietf-ip        | Static assignment of IPv6 address, e.g., *2001:db8:0:1::1/64*                                                                                     |
+| link-local       | ietf-ip[^2]    | (RFC4862) Auto-configured link-local IPv6 address (*fe80::0* prefix + interface identifier, e.g., *fe80::ccd2:82ff:fe52:728b/64*)                 |
+| global auto-conf | ietf-ip        | (RFC4862) Auto-configured (stateless) global IPv6 address (prefix from router + interface identifier, e.g., *2001:db8:0:1:ccd2:82ff:fe52:728b/64* |
+
+Both for *link-local* and *global auto-configuration*, it is possible
+to auto-configure using a random suffix instead of the interface
+identifier.

+To illustrate IP address configuration, the examples below uses a
+switch with a single Ethernet interface (eth0) and a loopback
+interface (lo). As shown above, these examples assume *eth0* has an
+IPv6 link-local address and *lo* has static IPv4 and IPv6 addresses by
+default.

+Subject: ip: Support IP address protocol
+
+IPv4 and IPv6 addresses can be assigned a protocol value that indicates the
+provenance of the IP address. The attribute is modeled after ip route
+protocols, and essentially allows the administrator or userspace stack to
+tag addresses in some way that makes sense to the actor in question.
+Support for this feature was merged with commit 47f0bd503210 ("net: Add new
+protocol attribute to IP addresses"), for kernel 5.18.
+
+In this patch, add support for setting the protocol attribute at IP address
+addition, replacement, and listing requests.
+
+An example session with the feature in action:
+
+	# ip address add dev d 192.0.2.1/28 proto 0xab
+	# ip address show dev d
+	26: d: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
+	    link/ether 06:29:74:fd:1f:eb brd ff:ff:ff:ff:ff:ff
+	    inet 192.0.2.1/28 scope global proto 0xab d
+	       valid_lft forever preferred_lft forever
+
+	# ip address replace dev d 192.0.2.1/28 proto 0x11
+	# ip address show dev d
+	26: d: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
