By setting 'auto', the zero address or the empty string as source
address (option ipaddr, option ip6addr), vxlan will choose one
dynamically. This helps in setups where a wan ip or prefix changes.
This corresponse to setting up an vxlan tunnel with:
proto vxlan6:
# ip link add vx0 type vxlan id ID local :: ...
proto vxlan:
# ip link add vx0 type vxlan id ID local 0.0.0.0 ...
While it is possible to not specify a source ip at all, the kernel will
default to setting up a ipv4 tunnel. The kernel will take any hint from
source and peer ips to figure out, what tunnel type to use. To make sure
we setup an ipv6 tunnel for proto vxlan6, this workaround is needed.
This will not change the behaviour of currently working configurations.
However this will allow former broken configurations, namely those not
specifying both a source address and tunnel interface, to setup a
tunnel interface. Previously those configurations weren't reporting an
error and were stueck in a setup loop like in Bug FS#3426.
This change lifts the currently very strict behaviour and should fix the
following bug:

You shouldn't need the overhead of GRE just to add multicast
capability on a point-to-point interface (for instance, you might
want to run mDNS over IPsec transport connections, and Avahi
requires IFF_MULTICAST be set on interfaces, even point-to-point
ones).

This package provides the necessary files to translate `config dsa_vlan`
and `config dsa_port` sections of `/etc/config/network` into appropriate
bridge vlan filter rules.
The approach of the configuration is to bridge all DSA ports into a logical
bridge device, called "switch0" by default, and to set VLAN port membership,
tagging state and PVID as specified by UCI on each port and on the switch
bridge device itself, allowing logical interfaces to reference port VLAN
groups by using "switch0.N" as ifname, where N denotes the VLAN ID.

Similar to wireguard, vxlan can configure multiple peers or add specific
entries to the fdb for a single mac address.
While you can still use peeraddr/peer6addr option within the proto
vxlan/vxlan6 section to not break existing configurations, this patch
allows to add multiple sections that conigure fdb entries via the bridge
command. As such, the bridge command is now a dependency of the vxlan
package. (To be honest without the bridge command available, vxlan isn't
very much fun to use or debug at all)
Field names are taken direclty from the bridge command.
Example with all supported parameters, since this hasn't been documented so
far:
config interface 'vx0'
option proto 'vxlan6' # use vxlan over ipv6
# main options
option ip6addr '2001:db8::1' # listen address
option tunlink 'wan6' # optional if listen address given
option peer6addr '2001:db8::2' # now optional
option port '8472' # this is the standard port under linux
option vid '42' # VXLAN Network Identifier to use
option mtu '1430' # vxlan6 has 70 bytes overhead
# extra options
option rxcsum '0' # allow receiving packets without checksum
option txcsum '0' # send packets without checksum
option ttl '16' # specifies the TTL value for outgoing packets
option tos '0' # specifies the TOS value for outgoing packets
option macaddr '11:22:33:44:55:66' # optional, manually specify mac
# default is a random address
Single peer with head-end replication. Corresponds to the following call
to bridge:
$ bridge fdb append 00:00:00:00:00:00 dev vx0 dst 2001:db8::3
config vxlan_peer
option vxlan 'vx0'
option dst '2001:db8::3' # always required
For multiple peers, this section can be repeated for each dst address.
It's possible to specify a multicast address as destination. Useful when
multicast routing is available or within one lan segment:
config vxlan_peer
option vxlan 'vx0'
option dst 'ff02::1337' # multicast group to join.
# all bum traffic will be send there
option via 'eth1' # for multicast, an outgoing interface needs
# to be specified
All available peer options for completeness:
config vxlan_peer
option vxlan 'vx0' # the interface to configure
option lladdr 'aa:bb:cc:dd:ee:ff' # specific mac,
option dst '2001:db8::4' # connected to this peer
option via 'eth0.1' # use this interface only
option port '4789' # use different port for this peer
option vni '23' # override vni for this peer
option src_vni '123' # see man 3 bridge

vxlan can be configured without a peer address. This is used to prepare
an interface and add peers later.
