hogelan is simple vxlan implementation using Linux tap interface.
ID : https://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-00
hogelan includes "vxland" and "vxlanctl" commands. vxland, is vxlan daemon, forwards packet to VXLAN Overlay Network. vxlanctl is command for controlling vxlan. You can create/destroy vxlan tunnel interface using vxlanctl. And configure access list about ARP/ND/MAC. It can work on Linux Only.
hogelan is experimental implementation. if you'd like to use simple vxlan implementation, please see http://github.com/upa/vxlan/
% git clone git://github.com/upa/hogelan.git
% cd hogelan
% make
% make install
Multicast Address and Interface are configured in /usr/local/etc/vxlan.conf . vxland can work with IPv4 and IPv6.
# vxlan.conf
multicast_address 239.0.0.1
multicast_interface eth0
vxland is daemon for forwarding packet.
- start : /etc/init.d/vxlan start
- stop : /etc/init.d/vxlan stop
Other configurations is installed by vxlanctl.
vxlanctl is command tool for configuring vxlan. you can create/destroy vxlan tunnel interface, and install Access list. All Access List affect as Out Bound Filter per VNI. if you want to use vlan, create vlan interface using vconfig.
### Usage ####
% vxlanctl --help
Usage :
vxlanctl [commands]
commands: (VNI is hex)
create <VNI> add vxlan interface
destroy <VNI> delete vxlan interface
acl <VNI> mac [deny|permit] <Mac Addr> Source Mac Address Filter
acl <VNI> arp [deny|permit] <v4Addr> ARP Target Address Filter
acl <VNI> ns [deny|permit] <v6Addr> NS Target Address Filter
acl <VNI> ra [deny|permit] RA Filter
acl <VNI> rs [deny|permit] RS FIlter
### Create vxlan interface ####
% vxlanctl create 0
created
%
% ifconfig vxlan0
vxlan0 Link encap:Ethernet HWaddr 06:b3:1a:45:86:9a

### using with 802.1q vlan ####
% vconfig add vxlan0 100
Added VLAN with VID == 100 to IF -:vxlan0:-
% ifconfig vxlan0.100 up
% ifconfig vxlan0.100
vxlan0.100 Link encap:Ethernet HWaddr 06:b3:1a:45:86:9a
inet6 addr: fe80::4b3:1aff:fe45:869a/64 Scope:Link

- Per VLAN Access List
- Per VLAN Forwarding Database (it is Per VNI FDB now)
- show command of vxlanctl
