vxlan-netmap
netmap is a framework for high speed packet I/O. about netmap, please see http://info.iet.unipi.it/~luigi/netmap/ . this implementation is vxlan gateway using netmap I/O.
./vxlan-netmap
usage of vxlan-netmap
-o : overlay interface name
-i : internal interface name
-s : source vtep address
-v : vni-vlan-mcastaddr mapping
ethtool -K ixgbe0 rxvlan off txvlan off
ethtool -K ixgbe1 rxvlan off txvlan off
gcc -g vxlan-netmap.c -o vxlan-netmap -lpthread
sudo ./vxlan-netmap -o ixgbe0 -i ixgbe1 -s 10.0.1.2 -v 1-10-239.0.0.10 -v 2-20-239.0.0.20
Packets including vlan id from a internal interface are encapsulated with a VNI which is configured by -v options, and transmited to vxlan overlay network from an overlay interface. specifying vlan id 0 means untaged packet.
Todo
- show commands
- strip vlan tag in overlay networks
