GVRP stands for GARP (Generic Attribute Registration Protocol) VLAN Registration Protocol. This project is a Layer 2 network protocol, for automatic configuration of switches in a VLAN network. Each VLAN switch is configured with the VLANs it is part of. GVRP will spread this information and configure the needed VLANs. So to add a switch to a VLAN, only 1 switch needs to be reconfigured. This is not the case within a standard VLAN, where all switches might need reconfiguration. gvrpcd implements end-node GVRP functionality as a user-space daemon. It generates periodically GVRP "JOIN" packets with information about VLANs that server has defined on given NIC, or more generically - that it wants to be able to connect to. This is especially useful for Linux-based routers or firewalls that use lots of VLANs. As new VLANs show up, or old ones are deleted, switch automatically reconfigures port VLANs membership. Compilation: simply run "make". Youll need libnet library header files. For usage help, see gvrpcd -h. You may want to run gvrpcd as daemon (gvrpcd -d) or (like me) as foreground process controlled by init. My example inittab entry (Debian): gvrp:23:respawn:/usr/local/sbin/gvrpcd -i eth0 -t 3 Format of VLAN config file (-f option) is compatible with kernels /proc/net/vlan/config file: two lines of file header (ignored), and in following lines VLAN configuration (one line per VLAN): < interface description (ignored) > | < VLAN ID > | < interface > Notice two spaces after VLAN ID. Example: --- CUT HERE --- blahblahignore blahblahignore blah | 123 | eth0 blah | 124 | eth0 --- CUT HERE ---.
