Description Alexander Kläser

Currently it is not possible to assign multiple IPv4 addresses to VLANs, Bonds, or Bridges. This is due to limitations in the naming convention of UCR. For physical devices, additional IPv4 addresses are assigned as suffix of the interface name, e.g. ethX_Y.

A possible solution could be a mapping similar to IPv6 addresses, i.e.:

  ethX/ipv6/<identifier>/...

Could be done together with Bug #32648.

Virtual-interfaces are deprecated, as they only work for IPv4 and not for IPv6.
Linux supports adding additional IP addresses to interfaces since a very long time by using "ip addr add ... dev ...".
(Even Debian has no special support for multiple IP addresses and just recommends to no longer use "iface ... inet static" but "iface ... inet manual" and to configure all addresses by hand through /etc/network/interfaces.)

For UCS this can be done through UCR:

xargs -d '\n' ucr set <<'__UCR__'
interfaces/eth0/options/1=up ip addr add 1.2.3.4/24 dev $IFACE
interfaces/eth0/options/2=down ip addr del 1.2.3.4/24 dev $IFACE
__UCR__

For bridges, VLANs and bonding interfaces this can even be done through the UMC "basic settings" module by adding the "up ... / down ..." part into the "Additional bridge/vlan/bonding options" text fields.
